Some UV cure schedules aren’t limited by chemistry — they’re limited by how many watts of the right wavelength can actually reach the bond line before the fixture cycle moves on.
Twice the Wattage, Concentrated Where It Counts
The Incure 282068, part of the Incure UV Curing Replacement Bulbs lineup, is a 200W UVA-optimised short arc mercury lamp for the S20™, doubling the wattage of the standard 100W broadband lamp (282008) while concentrating that output specifically in the 315–400 nm band where UV adhesives absorb. The result is higher irradiance at the cure point through the same lightguide configuration — useful when extended lightguide runs introduce transmission losses that push the 100W lamp’s delivered intensity below the activation threshold, or when the cure schedule is time-constrained and needs more available energy per second.
No Output Wasted Outside the Photoinitiator’s Absorption Band
Standard UV adhesive photoinitiators absorb in the 365–400 nm UVA range. The 100W broadband lamp spreads a portion of its output across 254 nm and 313 nm — energy that heats the assembly without advancing the cure for a UVA-formulated adhesive. The 282068’s UVA-transmitting, UVC-filtering quartz envelope concentrates the full 200W in the band the adhesive actually uses, so none of the added wattage over the 100W lamp goes toward wavelengths the formulation can’t absorb.
Removing UVC From the Process Entirely
The 100W broadband lamp’s 254 nm output is genuine UVC radiation, which triggers UVC-specific ventilation and extended operator PPE requirements in some jurisdictions. The 282068 suppresses sub-280 nm output by design — the same S20™ curing performance without that facility compliance layer. Where process or facility rules can’t accommodate UVC emission, or where the added ventilation and PPE overhead isn’t justified for a UVA-only adhesive, the 282068 is the correct lamp rather than a downgrade.
Deciding between the broadband 282008 and the UVA-concentrated 282068 comes down to what your adhesive’s photoinitiator system actually needs — Email Us with your formulation’s cure wavelength and Incure can confirm the right lamp.
Same Replacement Discipline as Every S20™ Lamp
Rated life is approximately 1,000 hours under standard conditions, with output degrading progressively before failure — schedule replacement on a fixed interval rather than waiting for the lamp to stop. At 200W, the envelope runs hotter than the 100W lamp, so the minimum 30-minute cooldown before handling matters even more here; never touch the quartz envelope with bare hands, and dispose of spent lamps per local hazardous waste regulations.
Matching lightguide length and configuration to whichever S20™ lamp you run keeps delivered irradiance predictable across the whole system. Review the Incure S20™ UV Arc Spot Lamp this lamp powers, and confirm your team’s Incure Vison™ eyewear is rated for this output level.
When Broadband Is Still the Right Answer
The 282068’s UVA concentration is a genuine advantage for UVA-formulated adhesives, but it isn’t a universal upgrade. If a process was originally qualified against the standard broadband 282008, switching to the 282068 changes the spectral input at the cure point even though both lamps fit the same S20™ housing — that’s a re-qualification event, not a drop-in swap. Formulations that rely on 254 nm or 313 nm activation, or processes that specifically call for UVC exposure ahead of bonding, need the broadband lamp regardless of the throughput or compliance advantages the UVA-concentrated option offers elsewhere.
Cooldown and Handling Discipline
Because the 282068 runs at 200W in an envelope originally sized for the same footprint as the 100W lamp, heat dissipation after shutoff takes longer than a quick visual check might suggest — the quartz envelope can remain hot well past the point where the lamp appears to have cooled by eye. Treating the minimum 30-minute cooldown as a hard floor rather than a rough guideline avoids both burn risk and the premature envelope stress that handling a still-hot lamp can introduce, which shortens service life independent of duty cycle.
A Reasonable Decision Framework
For a facility weighing the 282068 against the standard 282008, three questions in sequence usually settle it: is the current adhesive’s photoinitiator system genuinely UVA-only, or does it need 254/313 nm activation the 282068 suppresses? Is the process time-constrained or lightguide-length-constrained enough that the intensity increase would produce a measurable throughput or reliability gain? And can the facility accommodate the higher operating temperature and correspondingly longer cooldown period at 200W versus 100W? Answering all three affirmatively makes the 282068 a straightforward upgrade; answering any of them negatively is a reason to stay with the broadband lamp instead.
Lightguide Compatibility Carries Over
Like the standard broadband lamp, the 282068 is compatible with the full Incure LLG-Series lightguide range in any configuration — a lamp upgrade doesn’t require a parallel lightguide change. Because the 282068’s higher output is most valuable specifically at extended lightguide lengths where transmission losses are greatest, pairing it with a lightguide review makes sense: a longer lightguide run gains the most from the intensity increase, while a short, direct lightguide may see less practical benefit from the upgrade relative to its cost.
