Peak irradiance and total dose per pass sound like the same thing until a process actually needs one specifically and not the other — and the F500x2A is a useful case study in why that distinction matters. 590 mW/cm² Per Head — the Ceiling for Dual-UVA Configurations The Incure CDM™ / CDM™ Compact + F500x2A pairs either belt platform with two F500 UVA lamp heads in series — no UVC lamp head — delivering 590 mW/cm² at 365 nm per head, the highest per-lamp-head intensity of any dual-UVA configuration on the CDM™ fleet, ahead of the F400x2A's 490 mW/cm² and the F200x2A's 350 mW/cm² per head. For photoinitiator systems with a minimum irradiance threshold, or formulations that need above-threshold intensity to initiate the radical chain without extended exposure time, that peak intensity is the deciding spec. Doubling the F500x2AC at Every Belt Speed The single-assembly F500x2AC delivers 1,480 mJ/cm² UVA at 6 ft/min. The F500x2A places two F500 UVA heads in series on the same conveyor platform, doubling that to 2,960 mJ/cm² UVA at 6 ft/min — the same relationship the F400x2A and F200x2A hold to their respective single-assembly counterparts, just at the F500's higher per-head intensity. Where It Falls Short of the F400x2A — and Why Despite the higher per-head intensity, the F500x2A delivers less total energy per pass than the F400x2A at any given belt speed — 2,960 mJ/cm² versus 5,260 mJ/cm² UVA at 6 ft/min — because the F500's aperture is shorter in the belt-travel direction, so a part spends less total time under the beam even at higher instantaneous intensity. If total dose per pass is the primary requirement, the F400x2A is the correct configuration; if peak irradiance is what a formulation's photoinitiator system actually needs, the F500x2A is the right one despite the lower total-energy number. Sorting out whether a process needs peak intensity or total dose — they're not the same requirement — is worth confirming against the adhesive's actual photoinitiator data. Email Us with your formulation's specification and Incure can help match the configuration. A quick way to settle the question in practice: if a formulation cures reliably at a lower peak intensity given enough total exposure time, total dose is the governing variable and the F400x2A is likely the better fit. If cure quality drops sharply below a specific peak irradiance regardless of how much total time is allowed, the formulation has a genuine minimum-intensity threshold, and the F500x2A's higher per-head output is the configuration built to clear it. UVA-Only, Available on Both Platforms No UVC lamp head means no UVC ventilation or PPE overhead. The F500x2A is available on both the standard CDM™ (polypropylene belt) and CDM™ Compact (stainless-steel wire belt), sharing the same 3.0–6.5 inch curing height range and 5-inch maximum part width on either chassis. A mounting stand is not available for F500 configurations on either platform. Lamp head replacement is planned at the 1,000-hour threshold per head, and belt speed adjustment remains the only process control — no…

Choosing between a polypropylene and a stainless-steel conveyor belt shouldn't also mean choosing between lamp options — and on the CDM™ fleet, one arc configuration specifically avoids that trade-off. 40% More Intensity Than the F200x2AC The Incure CDM™ / CDM™ Compact + F400x2AC pairs either belt platform with a single F400x2AC lamp assembly — one UVA lamp head and one UVC lamp head, shipped as one unit — delivering 490 mW/cm² at 365 nm, 40% more peak irradiance than the F200x2AC's 350 mW/cm², in the same single-assembly broadband format. At 6 ft/min the dose rises from 2,250 mJ/cm² UVA (F200x2AC) to 2,630 mJ/cm² UVA, a 17% dose increase that translates directly into a proportional belt speed gain for a process already curing successfully at the lower intensity. The First Configuration on Both Belt Materials The F400x2AC is the first F-series configuration available on both the standard CDM™ (9-inch polypropylene belt) and the CDM™ Compact (9-inch stainless-steel wire belt) — the F100 and F200 heads are exclusive to the standard CDM™. That gives a line the choice of belt platform at order time without giving up broadband arc curing: polypropylene for general UV adhesive and coating work, or stainless-steel wire for processes where solvent exposure, elevated temperature, or washdown compliance rules out a polymer belt. The lamp head itself is identical on both platforms — only the conveyor chassis and part number prefix (CDM- versus CDMC-) differ. Highest Single-Assembly Dose in the Broadband Lineup Among every x2AC single-assembly broadband configuration on the fleet, the F400x2AC delivers the highest curing energy per pass at any given belt speed — 2,630 mJ/cm² UVA at 6 ft/min against 2,250 for the F200x2AC and 1,050 for the F100x2AC. At the slowest setting, 1.5 ft/min, it reaches 10,500 mJ/cm² UVA, supporting deeply pigmented or thick-layer formulations; at 12 ft/min, 1,320 mJ/cm² UVA supports high-throughput lines with a lower cure threshold. Working out which belt material actually fits a process, before locking in a lamp configuration that's available on both, is worth a direct conversation. Email Us with your process chemistry and Incure can help confirm. One Assembly, One Maintenance Cycle The UVA and UVC lamp heads replace as a single assembly rather than individually, planned at the 1,000-hour threshold. Maximum part width is 5 inches on either platform, with the same 3.0–6.5 inch curing height range on both. No external PLC/RS-232 control port is available on this arc configuration — belt speed adjustment is the only process control; for integration requiring external signals, an LED head from the Incure M-Series™ UV Focused Beam Curing Systems line is the alternative on this same chassis. This is one option in the broader Incure CDM™ UV Conveyor lineup — choosing belt material and lamp configuration together, rather than sequentially, avoids a mismatch discovered after ordering. The Part-Width Trade-Off That Comes With F400 Intensity Moving up to the F400x2AC's intensity tier means accepting a narrower process envelope than the F100/F200 lineup: maximum part width is 5 inches rather than 8,…

Some UV adhesive formulations don't fail to cure because the process is misconfigured — they fail because the pigment loading or bond thickness absorbs dose faster than any single-assembly lamp can deliver it. The Highest-Energy F400 Configuration on the Fleet The Incure CDM™ / CDM™ Compact + F400x2A pairs either belt platform with two F400 UVA lamp heads in series — no UVC lamp head — delivering 490 mW/cm² per head at 365 nm across a maximum 5-inch part width. At the slowest belt setting, 1.5 ft/min, that configuration accumulates 21,000 mJ/cm² UVA — the highest curing energy of any F400 configuration on either the standard CDM™ or the stainless-belt CDM™ Compact. At 6 ft/min it's still 5,260 mJ/cm² UVA, and at 12 ft/min, 2,640 mJ/cm² UVA. Exactly Double the F400x2AC, at Every Speed The single-assembly F400x2AC delivers 2,630 mJ/cm² UVA at 6 ft/min from one lamp assembly. The F400x2A places two of the same F400 UVA heads in series on the identical conveyor platform, so each part accumulates dose from both heads in one belt run — precisely double the F400x2AC's dose at every belt speed, with no change to part width, curing height, or system footprint beyond the second lamp head. For a process already running at target speed on the F400x2AC but not reaching full cure depth, the F400x2A is the direct step up on the same chassis. UVA-Only, Available on Either Belt Platform No UVC lamp head means no UVC ventilation, shielding, or PPE overhead beyond standard UV safety practice — a real advantage where UVC exposure management adds process complexity a UVA-only formulation doesn't require. The F400x2A is available on both the standard CDM™ (9-inch polypropylene belt) and the CDM™ Compact (9-inch stainless-steel wire belt), sharing the identical 3.0–6.5 inch curing height range on either chassis. If your adhesive's qualification data specifies broadband UVA + UVC exposure, the F400x2AC is the correct configuration instead. Confirming whether a formulation's pigment loading or bond thickness actually requires this level of dose — rather than defaulting to the highest-energy option available — is worth a direct check. Email Us with your cure depth requirements and Incure can help size the right configuration. A practical way to make that call is running a step-down test: cure a representative batch at the F400x2A's dose level, confirm full cure through the deepest point in the bondline, then repeat at the F400x2AC's single-head dose and check whether cure quality actually degrades. If the single-assembly configuration still passes, the dual-head F400x2A is available headroom rather than a requirement — useful to know before committing capital to the higher-tier configuration by default. Maintenance Across Two Heads Both lamp heads should be replaced on the same maintenance cycle, planned at the 1,000-hour threshold per head, to avoid one head degrading ahead of the other and skewing dose uniformity across the two exposure zones. As with every arc configuration on this fleet, belt speed adjustment is the only process control — no external PLC/RS-232 port is…

Throughput gains on a UV conveyor line usually come from one of two places: a faster belt, or more available irradiance per pass — and stepping up a single lamp assembly is often the simpler of the two to implement. 46% More Peak Irradiance, Same Belt Platform The Incure CDM™ + F200x2AC pairs the CDM™ 9-inch polypropylene belt conveyor with a single 600W F200x2AC lamp assembly — one UVA tube and one UVC tube, shipped as one unit. It delivers 350 mW/cm² at 365 nm, a 46% increase over the entry-level F100x2AC's 240 mW/cm², from the same broadband single-assembly format on the identical conveyor chassis. At 6 ft/min the dose increases from 1,050 mJ/cm² UVA (F100x2AC) to 2,250 mJ/cm² UVA — more than double the energy per pass at the same belt speed. Throughput Gain Without a Chassis Change That intensity difference directly shortens the minimum belt dwell time needed to reach cure threshold. A part that needs 6 ft/min with the F100x2AC to reach full cure can typically run at approximately 8–9 ft/min with the F200x2AC while maintaining the same UV dose — a real throughput gain from a lamp assembly swap on the same CDM™ conveyor, with no change to belt width or the rest of the platform. Full Broadband Compatibility in One Assembly The F200x2AC's single lamp assembly delivers simultaneous UVA and UVC exposure in one belt pass — no secondary lamp source or second conveyor stage required for adhesives specifying broadband arc-lamp cure. If a process is qualified under UVA-only exposure instead, the F200x2A (two UVA heads, no UVC) is the correct alternative rather than this single-assembly broadband configuration; the two aren't interchangeable once a qualification specifies one or the other. Figuring out whether the intensity jump from F100x2AC to F200x2AC is enough to hit a target belt speed — or whether the process needs to go further — is worth working through before ordering. Email Us with your current cure schedule and Incure can help size the right configuration. Dose Range and What Comes Next At 1.5 ft/min the F200x2AC accumulates 9,000 mJ/cm² UVA, supporting deeply pigmented formulations or thick adhesive layers that need extended exposure; at 12 ft/min the dose is 1,130 mJ/cm² UVA for high-throughput lines with a low cure threshold. If a process needs more intensity still, the F400x2AC steps up 40% further in the same single-assembly broadband format on the same conveyor chassis. As with every arc configuration on this platform, there's no external PLC/RS-232 control port — belt speed is the only process control, and an LED configuration such as the Incure M-Series™ UV Focused Beam Curing Systems head is the alternative where external control integration is required. This configuration sits within the broader Incure CDM™ UV Conveyor lineup — sizing a lamp configuration correctly the first time avoids a second equipment change later. Confirming the Throughput Estimate in Production The approximately 8–9 ft/min figure for matching the F100x2AC's dose at F200x2AC intensity is a reasonable starting estimate, but it's…

Deeply pigmented adhesives and thick bond layers both do the same thing to a UV cure schedule: they absorb dose before it reaches the depth that still needs to react, and the only real fix is more available energy per pass. The Ceiling Configuration for UVA-Only Arc Curing The Incure CDM™ + F200x2A pairs the CDM™ 9-inch polypropylene belt conveyor with two 600W F200 UVA lamp heads mounted in series, with no UVC tube. At 6 ft/min it delivers 4,500 mJ/cm² UVA — more than any other arc configuration on the CDM™ fleet at the same belt speed, including the F100x2AC (1,050), F100x2A (2,100), and F200x2AC (2,250). At the slowest setting, 1.5 ft/min, dose reaches 18,000 mJ/cm² UVA, giving formulations that need extended or high-energy exposure the widest dose headroom available on this platform. Doubling the F200x2AC at Every Belt Speed The F200x2AC delivers 2,250 mJ/cm² UVA at 6 ft/min from a single 600W lamp assembly. The F200x2A mounts two of the same 600W heads in series — each part passes under both in one belt run, accumulating exactly double the dose at every point across the speed range, from 18,000 mJ/cm² at 1.5 ft/min up to 2,260 mJ/cm² at 12 ft/min. In practice that means the F200x2A can run roughly twice the belt speed of the F200x2AC for an equivalent dose target, or hold the same speed with a full 2× safety margin built into every production run. UVA-Only by Design No UVC tube means no UVC ventilation or PPE overhead — this configuration is the right fit specifically when a process is qualified under UVA-only arc lamp exposure and the goal is maximum available UVA energy, not broadband coverage. If a formulation's qualification data specifies UVA + UVC together, the F200x2AC single-assembly configuration is the correct alternative; broadband qualification data doesn't transfer to this UVA-only configuration without re-validation. Working out whether maximum UVA dose or broadband coverage is what a specific adhesive actually needs is worth confirming directly — Email Us with your formulation's qualification data and Incure can help match the configuration. Maintenance and Uniformity Both lamp heads should be replaced on the same maintenance cycle — planned at the 1,000-hour threshold per head — to keep dose uniform across the two exposure zones rather than letting one head degrade ahead of the other. Dynamic uniformity at 2.0 inches is 0.82, consistent across the F-series arc lineup on this platform. As with every arc configuration on the CDM™, there's no external PLC/RS-232 port; for process integration requiring external control signals, an LED configuration on the same chassis is the alternative — see the Incure L-Series™ UV LED Flood Lamps family for the LED heads available on this platform. This is one configuration within the broader Incure CDM™ UV Conveyor lineup — matching maximum available dose to what a formulation actually requires avoids over- or under-specifying the lamp configuration. The Same Chassis Handles the Whole Range Because every F100/F200 arc configuration on the CDM™ shares the same 9-inch…

Not every UV adhesive process was formulated for LED wavelengths or UVA-only exposure — a lot of production adhesive chemistry was developed against mercury-arc lamps, UVC included, and the CDM™ + F100x2AC is built for exactly that qualification. One Assembly, Two Wavelength Ranges The Incure CDM™ + F100x2AC pairs the CDM™ 9-inch polypropylene belt conveyor with a single F100x2AC lamp assembly — one 400W UVA tube (365 nm peak) and one UVC tube (254 nm), both mounted in one overhead unit shipped and installed as a single part. Many adhesives originally developed for arc-lamp spot curing use photoinitiators that respond to both UVA and UVC; the F100x2AC delivers that broadband spectrum in one part number rather than requiring a separate UVC source layered onto a UVA-only system. Full 9-Inch Belt Coverage The F100x2AC illuminates the complete 9-inch belt width in a single overhead pass — meaningfully wider than the M-Series focused-beam configurations available on the same CDM™ platform, which cure 1-inch (M51) or 2-inch (M62) strips matched to narrow bond lines. When the assembly footprint or adhesive pattern spans the full part width and precise beam targeting on a narrow line isn't the goal, the F100x2AC's flood coverage is the more direct fit than a focused-beam configuration. Entry-Level Intensity, With a Clear Upgrade Path At 6 ft/min the F100x2AC delivers 1,050 mJ/cm² UVA (1,000 mJ/cm² UVV) per pass — enough for many mercury-arc compatible UV adhesives running at standard production speeds. When a process needs more — faster belt speeds, thicker bondlines, or pigmented coatings that absorb more of the incident dose — the F200x2AC delivers 350 mW/cm² at 365 nm on the identical 9-inch belt width and conveyor platform, a direct step up with no chassis change required. Confirming whether your adhesive's qualification data actually calls for UVC alongside UVA — rather than assuming broadband is always the safer choice — is worth doing before ordering. Email Us with your process specification and Incure can help confirm. Replacement and Control Notes The UVA and UVC tubes ship and replace as a single assembly — individual tube replacement isn't supported, and both are planned for replacement at the 1,000-hour threshold or when measured intensity drops below process minimum. There's no external PLC/RS-232 control port on this configuration; belt speed is the only process control available. For integration requiring external control signals, an LED configuration on this same chassis is the alternative — see the Incure M-Series™ UV Focused Beam Curing Systems whose beam heads also run on the CDM™. This is one entry point into the Incure CDM™ UV Conveyor family — whether broadband or UVA-only, LED or arc, matching configuration to actual qualification data is the first step before ordering. A Sensible Starting Point for a New Line For a newly commissioned process with adhesive qualification data still being finalized, the F100x2AC's combination of full belt-width coverage, broadband spectral compatibility, and the lowest capital cost in the arc lineup makes it a reasonable default to commission a line with…

When a conveyor process is already running at target throughput but isn't quite reaching full cure, the instinct is to slow the belt down — the CDM™ + F100x2A exists so that isn't the only option. Two Heads, Double the Dose, Same Speed The Incure CDM™ + F100x2A pairs the CDM™ 9-inch polypropylene belt conveyor with two 400W F100 UVA lamp heads mounted in series along the belt. Each part passes under both heads in a single pass, accumulating dose from each consecutively — the result is 2,100 mJ/cm² UVA at 6 ft/min, exactly double what the single-assembly F100x2AC delivers at the same belt speed. That doubled dose holds across the full speed range: at 12 ft/min the F100x2A still delivers 1,060 mJ/cm² UVA, matching what the F100x2AC achieves at half that speed. UVA-Only, No UVC Compliance Layer The F100x2A configuration uses two UVA lamp heads only — there's no UVC tube. Facilities that haven't installed UVC-rated exhaust ventilation, or that run under a process qualification specified as UVA-only arc lamp exposure, get the full doubled-dose benefit without introducing a UVC handling requirement. If an adhesive's SDS or qualification data specifies mercury-arc exposure that includes UVC, the F100x2AC single-assembly configuration is the correct choice instead — the two configurations aren't interchangeable once UVC is part of the qualification. Where the Extra Dose Actually Helps Doubled UVA dose isn't just a safety margin on paper — it directly supports deeper bondline cure, UV-absorbing or pigmented formulations that need more energy to reach full conversion through the material depth, or a belt speed increase for the same dose target a single head can only hit at half the throughput. For a line running at process minimum with a single F100 head and looking for either more margin or more speed, the F100x2A is the direct next step on the same conveyor platform. Working out whether a UVA-only or broadband configuration fits your adhesive's actual qualification data is worth confirming before ordering — Email Us with your process specification and Incure can help match the right configuration. No External Control, and What That Means Like the rest of the F-series arc configurations on the CDM™, the F100x2A has no external PLC or RS-232 control port — belt speed adjustment is the only process control available. For process integration that requires external control signals, an LED configuration on the same conveyor chassis is the alternative path — see the Incure L-Series™ UV LED Flood Lamps family that includes the CDM™-compatible L64 and L88 heads. Bulb replacement is planned at the 1,000-hour threshold per head, and both heads should be replaced on the same maintenance cycle to keep dose uniform across the two exposure zones. This configuration is one of several Incure lamp-head options on the Incure CDM™ UV Conveyor platform — matching lamp configuration to both your adhesive's dose requirement and your line's control needs takes a look at the whole process. A Straightforward Upgrade Path Because the F100x2A shares its conveyor chassis and…

A polypropylene conveyor belt works fine for most UV curing lines right up until the process itself rules polypropylene out — solvent exposure, elevated part temperature, or a belt-material compatibility requirement that no amount of process tuning solves. A Different Belt, the Same Lamp Heads The Incure CDM™ Compact is a UV conveyor belt chassis built on a 9-inch stainless-steel wire belt rather than the standard CDM™'s polypropylene belt, for curing processes where polypropylene isn't suitable. It runs the identical F400 and F500 high-intensity mercury-arc lamp heads available on the standard CDM™, in x2AC single-assembly broadband or x2A dual-lamp UVA-only configurations, with no change to curing performance between the two chassis. The chassis ships without a lamp head — belt speed adjusts from 1.5 to 12.0 ft/min either way. Same Curing Envelope, Different Footprint Curing height (3.0–6.5 inches) and belt speed range match the standard CDM™ running the same F400 or F500 head exactly, so an existing F400/F500 cure schedule qualified on one platform transfers directly to the other without re-validation. What changes is the chassis itself: at 76 × 37 × 34 cm, the CDM™ Compact is meaningfully smaller than the standard CDM™'s 137 × 36 × 41 cm footprint — a real advantage for a line dedicated to F400 or F500 curing that doesn't need the standard chassis's full 12-configuration compatibility range. Scoped Deliberately, Not a Downgrade The CDM™ Compact is not a smaller version of the full CDM™ line — it's scoped specifically to the two highest-intensity F-Series™ configurations. For UV LED lamp heads, or the wider F100/F200 arc configurations, the standard CDM™ is the correct platform; the Compact chassis doesn't support them. That trade-off is deliberate: a line that only ever needs F400 or F500 intensity gains a smaller footprint and a non-polymer belt without losing anything it was actually going to use. Confirming whether stainless-steel wire or polypropylene is the right belt material for a given process, before committing to a chassis, is worth a direct conversation — Email Us with your process chemistry and Incure can advise. Maximum Part Width and Ordering Maximum part width on the CDM™ Compact is up to 5 inches, and lamp head configuration — F400x2AC, F400x2A, F500x2AC, or F500x2A — is selected at order under the CDMC- part number prefix. A mounting stand is available as an optional accessory for F400 configurations, though not for F500. Because chassis and lamp head are ordered as separate line items, confirming both the belt material and the exact lamp configuration up front avoids a mismatch between what the line actually needs and what ships. Matching belt material, lamp head, and cure schedule takes a full look at the whole Incure conveyor platform, not just the chassis spec sheet. See the Incure CDM™ UV Conveyor family this chassis belongs to, review the Incure F-Series™ UV Arc Flood Lamps that power the F400/F500 configurations, and confirm your team's Incure Vison™ eyewear is rated for whichever lamp head you specify. Power, Cooling, and Footprint Detail…

Not every adhesive formulation was built around a UVA-optimised lamp, and forcing one onto a process it wasn't qualified against is how a cure schedule quietly stops matching the datasheet. Full Broadband Where the Metal Halide Lamp Concentrates The Incure 282047, part of the Incure UV Curing Replacement Bulbs lineup, is a 400W short arc mercury lamp for the F-Series™ UV arc flood curing systems, delivering the complete mercury line spectrum — 254 nm, 313 nm, 365 nm, and 405 nm — where the factory-standard metal halide lamp (282021) concentrates output specifically in the UVA band. Use the 282047 when the adhesive formulation specifies broadband UV activation, requires UVC for surface treatment, or was originally qualified against a mercury arc spectrum rather than metal halide. Like-for-Like Replacement, No Re-Qualification Spectral output, arc geometry, and wattage all match what an F-Series™ system running a mercury-arc process was originally characterised against. Installing the 282047 as a direct replacement maintains the irradiance profile the existing cure schedule depends on — any deviation in lamp type, wattage, or arc geometry changes that profile at the curing area and invalidates the current process validation. This is the straightforward swap-the-lamp, keep-the-schedule option for mercury-qualified lines. Arc Geometry Built for the F-Series™ Reflector The F-Series™ lamp housing is designed around a short arc point source. A longer or more diffuse arc spreads emission across a wider zone, reducing how efficiently the reflector can redirect that output back to the curing area — the practical effect is a lower average intensity even at the same rated wattage. The 282047's arc geometry matches what the F-Series™ reflector optics were designed for, delivering full rated intensity at the specified working distance rather than a degraded average across an oversized arc. Confirming whether a given adhesive's SDS or qualification data calls for broadband exposure or UVA-only is worth doing before ordering replacement lamps in volume — Email Us with your formulation details and Incure can confirm the right lamp type. UVC Handling Requirements Apply Here Because the 282047 produces genuine UVC radiation at 254 nm, it must be operated only within the shielded F-Series™ lamp housing with all guards in place — this is not optional, unlike with the UVC-free metal halide alternative. Rated lamp life is approximately 2,000 hours, with output degrading progressively before failure; allow 2–3 minutes of warm-up before each cure cycle and a minimum 30-minute cooldown before handling. Dispose of spent mercury-containing lamps per local hazardous waste regulations. Whichever lamp type an F-Series™ line runs, UV shielding and eye protection rated for that lamp's actual output belong in the same review. See the full Incure F-Series™ UV Arc Flood Lamps this bulb powers, and confirm your team's Incure Vison™ eyewear is rated for broadband mercury arc output — UVC exposure needs different protection than UVA-only sources. Shielding Matters More With UVC in the Mix Because the 282047 emits genuine UVC radiation, the physical shielding around an F-Series™ station running this lamp carries more weight than it does…

An irradiance spec on a datasheet is only as good as the light source it was measured with — change the lamp and the number on the page stops describing what's actually happening at the curing area. The Reference Lamp for F-Series™ Performance Data The Incure 282021, one model in the Incure UV Curing Replacement Bulbs lineup, is the factory-installed 400W metal halide lamp for the F-Series™ UV arc flood curing systems, including the F100 and F400. Every published F-Series™ irradiance rating — 225 mW/cm² for the F100, 490 mW/cm² for the F400 — was measured and characterised against this specific lamp. Installing the 282021 as a replacement delivers the rated intensity the datasheet specifies; substituting a different lamp type changes the spectral distribution and means the published specification can no longer be relied on without a new irradiance measurement. Metal Halide Dopants Shift Output Toward UVA A standard 400W mercury arc distributes output across 254 nm, 313 nm, 365 nm, and 405 nm. Most UV adhesive photoinitiators absorb in the 365–400 nm band — output at 254 nm and 313 nm heats the assembly without advancing the cure. Metal halide dopants shift the 282021's arc output into the UVA range, so more of the 400W reaches the bond line as usable curing energy. In practice that means shorter cure times and lower part temperatures than an equivalent-wattage mercury arc lamp delivers for the same UVA-formulated adhesive. No UVC Emission The mercury-arc alternative (282047) produces genuine UVC radiation at 254 nm, which triggers UVC-rated ventilation and extended PPE requirements in regulated facilities. The 282021 produces none — the same F-Series™ cure performance without that additional compliance layer. Where facility or process rules can't accommodate UVC, or where the ventilation overhead isn't justified for a UVA-qualified adhesive, the 282021 is the standard choice, not an exception. If your F-Series™ cure schedule was originally qualified against a mercury-arc lamp rather than metal halide, switching lamp types changes the spectral input enough to require re-qualification — Email Us to confirm which lamp your process was validated against before ordering. Warm-Up Time and Replacement Interval Rated lamp life is approximately 2,000 hours under standard conditions, with output loss progressive rather than sudden — schedule replacement at the rated interval based on cumulative hours instead of waiting for visible failure. Allow 2–3 minutes of warm-up before starting a cure cycle so the arc reaches full operating temperature and irradiance stabilises; after shutoff, allow a minimum 30-minute cooldown before handling, and never touch the quartz envelope with bare hands. A flood lamp is only one variable in curing-area intensity — reflector condition, working distance, and eye protection all shift the delivered dose from the same rated Incure lamp. Review the Incure F-Series™ UV Arc Flood Lamps this bulb powers, and confirm your team's Incure Vison™ eyewear is rated for F-Series™ output. Two Systems, One Lamp The 282021 is the compatible replacement lamp for both the F100 and F400 flood curing systems — the same part number…
