A bench-mount lamp is stuck at the bench — but a repair station, a fixture on a moving line, or an assembly that can’t be brought to a fixed lamp all need the UV source to come to the part instead.
A Portable Lamp That Switches Between Flood and Focused Beam
The Incure F400 is a portable handheld UV arc flood curing lamp delivering 490 mW/cm² UVA in a unit built to go to the part rather than the other way around — with the ability to switch between a standard 5″×5″ flood beam and an optional 5″×3″ focused beam without changing lamps. The bench-mount F100 and F200 cover a larger curing area but are fixed at the bench; the F500 delivers more raw intensity but has no focused-reflector option. The F400 is the only F-Series™ portable that combines meaningful output with switchable beam geometry.
Portable Where Bench-Mount Equipment Cannot Go
The F100 and F200 deliver UV only at the bench — the part has to come to the lamp. The F400 reverses that relationship: carry the lamp to the assembly fixture, the repair station, or directly along the production line. Parts cure in place without repositioning fixtures or moving assemblies mid-build, which matters on lines where the bonded joint is inconvenient or impossible to bring to a fixed lamp position.
Confirming whether a portable or bench-mount lamp actually fits a given workflow is worth checking before ordering. Email Us with the process layout and Incure can help confirm the right F-Series™ configuration.
The Only F-Series™ Handheld With a Focused Reflector Option
The optional 5″×3″ focused reflector concentrates output to 240 mW/cm² at 3.0 inches — 20% higher than the standard parabolic reflector at the same working distance — for narrow bond lines, edge seals, and joints where a full 5″×5″ flood beam would expose adjacent components unnecessarily. No other F-Series™ handheld, including the higher-output F500, offers this switchable option.
490 mW/cm² Across a 5″×5″ Area at 2.0 Inches
The 400W metal halide arc lamp delivers broadband UVA (315–400 nm), UVB (280–315 nm), and visible output to 420 nm — 490 mW/cm² at 2.0-inch working distance with the standard parabolic reflector, dropping to 200 mW/cm² at 3.0 inches; the optional focused reflector holds 240 mW/cm² at that same 3.0-inch distance instead. Lamp life is rated at roughly 2,000 hours, forced-air cooled, auto-ranging 100–120/200–240 VAC input for both domestic and international use.
Choosing Between the Flood and Focused Configurations
The standard parabolic reflector delivers full output across the complete 5″×5″ curing area, appropriate when the whole footprint needs UV exposure. The focused reflector trades curing area for higher irradiance in a narrower zone — the right call when adjacent components, coatings, or plastics near the bond line shouldn’t receive UV exposure. Because the reflector is a specified accessory rather than a field-adjustable setting, confirm which geometry the process needs at time of order.
Where the F400 Sits in the F-Series™ Range
The F400 is one of two portable handhelds in the Incure F-Series™ UV Arc Flood Lamps lineup, alongside the higher-output F500. Both share the 5″×5″ standard curing area and forced-air cooling, but only the F400 offers the focused-reflector option — the F500 trades that flexibility for a straight intensity increase in the same handheld form.
Shielding and Safety Equipment
UV protective goggles ship with the unit. Because the F400 is handheld rather than bench-mounted, Incure Perimeter™ UV shields — designed for the F-Series™ stand configurations — aren’t applicable here; operator eyewear rated to the Incure Vison™ UV eye protection specification is the primary protection during handheld operation.
Handheld Operation Puts More Weight on Operator Technique
Unlike a bench-mount lamp with a fixed working distance built into the mounting hardware, a handheld unit’s actual working distance depends on how the operator holds it against or above the part — a real source of cure-time variability that a bench-mount configuration doesn’t share. Because output falls off meaningfully between 2.0 and 3.0 inches (from 490 mW/cm² down to 200 mW/cm² on the standard reflector), training operators to maintain a consistent working distance matters more with the F400 than it would with a fixed-mount F100 or F200, particularly on processes qualified against a specific dose at a specific distance.
Repair and Field-Style Applications the Bench-Mounts Can’t Reach
Because the F400 goes to the part rather than the part coming to a bench, it fits use cases the F100, F200, and F200P simply can’t address — a repair on an assembly too large or too fixed to move to a bench station, a spot-cure on a line where the joint is inconveniently positioned mid-fixture, or field-style rework where the assembly stays in place and the lamp travels to it. The tradeoff for that mobility is losing the F100’s larger 8″×6″ curing area — a handheld unit’s smaller 5″×5″ (or narrower, with the focused reflector) footprint means more passes on a large bonded area, so portability and coverage area remain a genuine tradeoff rather than something the F400 solves for free.
Confirming Output Before Specifying a Reflector
Peak UVA intensity is measured at the specified working distance with the lamp at operating temperature; actual intensity varies with lamp age, ambient temperature, and working distance. The focused reflector is an optional accessory specified at time of order rather than a swap made in the field.
