When reflector flexibility isn’t the requirement and raw output is, trading the F400’s optional focused beam for a straight intensity increase in the same handheld form is the more direct fix.
Maximum Output in the Portable Handheld Form Factor
The Incure F500 is a portable, high-intensity UV arc flood curing lamp delivering 590 mW/cm² UVA — 20% more than the F400 — in the same portable handheld form factor, from a 600W metal halide lamp against the F400’s 400W. The F400 offers an optional focused reflector for narrow bond lines; the F500 trades that flexibility for maximum output across the full 5″×5″ parabolic beam instead. When cure time is the bottleneck and the standard flood geometry already fits the joint, the F500 is the highest-output portable in the F-Series™.
20% More Intensity in an Identical Handheld
The F400 delivers 490 mW/cm² at 2.0 inches from its 400W lamp; the F500 delivers 590 mW/cm² from a 600W lamp in an identical portable housing. At the same working distance, that roughly 100 mW/cm² difference translates directly into shorter required exposure time for a given UV dose — with no fixture change and no new process qualification beyond re-timing the exposure.
Confirming whether output or reflector flexibility matters more for a given handheld application is worth checking before choosing between the F400 and F500. Email Us with the process details and Incure can help confirm the right fit.
Shorter Cure Cycles on the Production Floor
UV dose is intensity multiplied by time, so a 20% higher output translates to a proportionally shorter exposure time for the same delivered dose. Production environments where operators hand-cure at pace — potting fills, edge seals, fixture bonding — finish faster per part as a direct result. The F500 is built for lines where throughput, not reflector geometry, is the actual bottleneck.
590 mW/cm² UVA at 2.0 Inches
The 600W metal halide arc lamp delivers broadband UVA (315–400 nm), UVB (280–315 nm), and visible output to 420 nm — 590 mW/cm² at 2.0-inch working distance, 270 mW/cm² at 3.0 inches, across the full 5″×5″ parabolic curing area. Lamp life is rated at roughly 2,000 hours, forced-air cooled, auto-ranging 100–120/200–240 VAC input for domestic and international use. The removable, self-contained handheld lamp head weighs 3.15 lb.
No Focused-Reflector Option — a Deliberate Tradeoff
Unlike the F400, the F500 doesn’t offer a focused-reflector accessory — its parabolic reflector is the only configuration available. For processes that need a narrower, higher-irradiance beam to avoid over-exposing adjacent components, the F400’s optional focused reflector fills that gap instead. The F500’s design commits fully to maximum flood output rather than splitting the difference between output and beam-geometry flexibility.
Where the F500 Sits in the F-Series™ Range
The F500 is the highest-intensity handheld in the Incure F-Series™ UV Arc Flood Lamps lineup, above both the F400 portable and the bench-mount F100/F200/F200P models at the same 5″×5″ footprint tier. Choosing the F500 over the F400 comes down to whether the process ever needs the focused-reflector option — if it doesn’t, the F500’s higher baseline output is the more direct route to shorter cure cycles.
Handheld Safety Considerations
UV protective goggles ship with the unit. Because the F500 is handheld and moves with the operator rather than staying fixed at a bench station, eyewear rated to the Incure Vison™ UV eye protection specification is the operator’s primary protection, and consistent handling practice matters more than on a fixed-position bench lamp.
The Lightweight Head Matters as Much as the Output
At 3.15 lb, the F500’s removable, self-contained handheld lamp head is light enough for extended hand-held use without operator fatigue becoming a factor across a full shift of potting fills, edge seals, or fixture bonding. That’s not incidental to the intensity story: a higher-output lamp only shortens cure cycles in practice if the operator can hold it steady and consistently positioned at the qualified working distance for every part, and a lighter head makes that consistency easier to maintain over hundreds of repetitions than a bulkier unit would, even one with identical optical output.
Standardizing on the F500 Across a High-Throughput Floor
For a facility running many hand-cure stations where reflector flexibility genuinely isn’t needed, standardizing on the F500 rather than mixing F400 and F500 units simplifies spare-parts inventory and operator training — every handheld lamp on the floor behaves identically, with the same output, the same roughly 2,000-hour lamp life, and the same physical form factor. That consistency is worth weighing against the F400’s added reflector flexibility on lines where every station’s bond geometry is similar enough that the focused-reflector option would rarely get used anyway.
Verifying Output as the Lamp Ages
Peak UVA intensity is measured at the specified working distance with the lamp at operating temperature; actual intensity drifts with lamp age, ambient temperature, and working distance, so cure cycles qualified early in the roughly 2,000-hour lamp life should be re-verified as the bulb approaches replacement.
