Safety & Installation Guidelines
- Qualified Installation: Disconnect power at the breaker before installation. LED retrofit installation requires knowledge of luminaire electrical systems — if not qualified, contact a licensed electrician.
- Ballast Removal: This is a Type B (ballast bypass) lamp — the existing ballast (and starter, if present) must be fully removed, not just bypassed. Wire for double-ended power only, per Halco’s installation guide.
- Not for Dimmers or Emergency Exits: Do not use with dimmers. This lamp is not intended for use with emergency exit fixtures.
- Marking: Mark the retrofitted luminaire "This luminaire has been modified to operate LED lamps. Do not attempt to install or operate fluorescent lamps in this luminaire," per code.
- Disposal: Dispose of the removed ballast and fluorescent lamps per local government regulations.
