200W UVA Short Arc Mercury UV Replacement Lamp

Incure 200W UVA Short Arc Mercury UV Replacement Lamp (Part No. 282068) is the highest-output option for the S20™ — 200W concentrated into the UVA band where UV adhesives cure. This lamp delivers more irradiance at the cure point than the 100W broadband and targets it at the wavelengths UVA-formulated adhesives actually absorb. Where the 100W broadband maintains UVC and UVB output for broad chemistry compatibility, this lamp trades that range for intensity and efficiency. Use it when your adhesive is UVA-formulated, your process is throughput-constrained, or your facility cannot accommodate UVC emission.

Doubles the Irradiance at the Cure Point — Reaches Depths the 100W Broadband Cannot

200W vs 100W means the S20™ delivers higher irradiance through the same lightguide configuration. At extended lightguide lengths, transmission losses reduce intensity proportionally — the higher source output maintains useful irradiance at cure points where the 100W lamp falls below the activation threshold. Choose this lamp when cure schedules are time-constrained or when the fixture geometry requires a longer lightguide run.

UVA-Concentrated Output — Every Available Watt Drives the Photochemistry

Standard UV adhesive formulations optimise their photoinitiator absorption for 365–400 nm UVA. The 100W broadband lamp distributes a portion of its output across 254 nm and 313 nm — wavelengths that contribute little to cure for UVA-formulated adhesives. This lamp concentrates output in the photoinitiator absorption band; no output is wasted at wavelengths the adhesive does not use.

No UVC Output — Full S20™ Performance Without UVC Compliance Overhead

UVC (sub-280 nm) emission from the 100W broadband lamp requires UVC-specific ventilation and extended operator PPE protocols in some jurisdictions. The UVA-optimised envelope of this lamp suppresses sub-280 nm output, removing these requirements from the process environment. Use this lamp where process or facility compliance cannot accommodate UVC emission.

P/N282068

Rated lamp life of ~1,000 hours is under standard operating conditions. Actual life varies with duty cycle, thermal cycling frequency, and operating environment. Replace proactively on a scheduled maintenance interval rather than waiting for lamp failure — output degrades progressively with use before total failure occurs. At 200W, the lamp envelope reaches higher operating temperatures than the 100W lamp; allow a minimum of 30 minutes after shutoff before handling. Do not touch the quartz envelope with bare hands; skin oils create hot spots that shorten lamp life. Dispose of spent mercury-containing lamps in accordance with local hazardous waste regulations.
