Per GE footnote 14, this lamp must be operated only in an enclosed fixture rated for this product (UL Standard 1572 / 21 CFR 1040.30) — the arc tube can emit UV radiation and the lamp can cause serious skin burn and eye inflammation if the outer envelope is broken or punctured while the arc continues to operate.

Before Ordering – Verify
- Confirm the base type (30x70 Cyl (165mm lead)) and voltage (225V) match your fixture before ordering.
- Confirm your fixture is fully enclosed and UL-1572 rated for this product — CSR/CSD discharge lamps are not rated for open fixtures.

Safety and Handling Guidelines

Do not use where people will remain more than a few minutes unless adequate shielding or other safety precautions are used.
- Turn power off before inspection, installation, or removal — risk of electrical shock.
