400W Metal Halide UV Replacement Lamp
Incure 400W Metal Halide UV Replacement Lamp (Part No. 282021) is the factory-installed lamp for the F-Series™ — the standard behind every published irradiance specification. Metal halide dopants shift the 400W arc output toward the UVA band where UV adhesives cure, delivering more useful irradiance at the curing area than a broadband mercury arc at the same wattage. The F-Series™ intensity ratings — 225 mW/cm² for the F100, 490 mW/cm² for the F400 — were measured and characterised against this lamp. Where the 400W mercury arc maintains the complete broadband spectrum for formulations that require UVC activation, this lamp trades UVC coverage for maximum UVA delivery and a clean process environment with no UVC compliance overhead.
More UVA at the Cure Point — Every Available Watt Concentrated Where Adhesives Absorb
The 400W mercury arc distributes output across 254 nm, 313 nm, 365 nm, and 405 nm. Standard UV adhesive photoinitiators absorb in the 365–400 nm band; output at 254 nm and 313 nm heats the assembly without advancing the photochemistry. Metal halide dopants shift the arc output into the UVA range — more of the 400W reaches the bond line as useful curing energy, resulting in shorter cure times and lower part temperatures compared to an equivalent-wattage mercury arc.
No UVC Emission — No UVC Safety Infrastructure Required
The 400W short arc mercury lamp produces UVC radiation at 254 nm, which requires UVC-rated ventilation and extended operator PPE protocols in regulated environments. The metal halide lamp produces no UVC — the same F-Series™ cure performance without additional facility compliance requirements. Where process or facility regulations cannot accommodate UVC emission, this is the correct lamp choice.
Factory Performance Specification — Rated F-Series™ Intensity Characterised Against This Lamp
The F-Series™ irradiance specifications were measured and published using the factory-installed metal halide lamp. Installing this lamp delivers the rated intensity the F-Series™ datasheet specifies. Substituting the mercury arc changes the spectral distribution and requires a new irradiance measurement before the published specification can be relied upon for process validation.

Rated lamp life of ~2,000 hours is under standard operating conditions. Actual life varies with duty cycle, on/off cycling frequency, and operating environment. Metal halide lamps lose output progressively before total failure — schedule replacement at the rated interval based on cumulative operating hours rather than waiting for the lamp to stop. Allow a minimum warm-up period of 2–3 minutes before initiating a cure cycle; irradiance stabilises as the arc reaches full operating temperature. After shutoff, allow a minimum cool-down of 30 minutes before handling the lamp. Do not touch the quartz envelope with bare hands; skin oils create hot spots that reduce lamp life. Dispose of spent metal halide lamps in accordance with local regulations.
