Important Safety & Installation Notes
UV Radiation Warning: These lamps can cause serious skin burns and eye inflammation from short-wave ultraviolet radiation if the outer envelope is broken or punctured. Use only in suitably enclosed luminaires.
Mandatory Safety Precautions
- Do not use where people remain for more than a few minutes unless adequate shielding is provided
- Use 4000V pulse-rated sockets only
- Thermally protected / overcurrent-protected ballast required
- Ensure protective shielding is installed and intact at all times
- Consider lamps with automatic extinguishing features for high-risk areas
- Complies with FDA radiation performance standard 21 CFR Subchapter J (USA: 21 CFR 1040.30, Canada: SOR/DORS/80-381)
