Critical Safety Notice

WARNING: These lamps can cause serious skin burns and eye inflammation from shortwave ultraviolet radiation if the outer envelope is broken or punctured. Do not use where people will remain for more than a few minutes unless adequate shielding or other safety precautions are used. Certain lamps that will automatically extinguish when the outer envelope is broken or punctured are commercially available.

This lamp complies with FDA radiation performance standard 21 CFR Subchapter J (USA: 21 CFR 1040.30, Canada: SOR/DORS/80-381).

Mandatory Safety Precautions

Avoid use in areas where people remain for extended periods without UV shielding
Ensure adequate shielding is always in place
Consider lamps with automatic extinguishing features for high-risk areas
Fixture must be suitably enclosed (E-type rating)
Use only with pulse-rated sockets rated for 4000V
