Tools & Supplies:
Cotton gloves or finger cots

WARNING: Remove power from luminaire before performing any maintenance procedures.
CAUTION: Refer to "Proper Lamp Servicing and Operation" on page 22 before handling the lamp.
CAUTION: Wear cotton gloves or finger cots while servicing lamp. Touching the lamp glass with bare
fingers will leave oil and cause the lamp to explode or burn out early. Clean with alcohol wipe after installing.
To replace lamp:
Step 1. Remove power from lamp and allow lamp to cool for at least 5 minutes.
Step 2. Remove power from luminaire.
Step 3. At rear lamp access door, push down on latch to open door. Refer to Figure 3-9 on next page.
Step 4. In an alternating fashion, turn two thumbscrews counter-clockwise until lamp socket is loose.
Do not completely loosen one thumbscrew and then loosen the other. Loosen each one a little at a time in
an alternating fashion to avoid breaking the socket or lamp.
Step 5. Pull lamp socket straight out of luminaire.
Step 6. Remove lamp from socket.
Step 7. Install new lamp in socket, noting two different size pins. Lamp will only fit in socket in one orientation.
Step 8. Ensure lamp base is fully seated so that it touches contacts at four corners of socket.
Step 9. Using supplied alcohol wipe, carefully - but thoroughly - clean glass bulb.
Step 10. Align metal lamp wire with keyed hole at back of luminaire. Carefully re-install lamp socket without touching
glass bulb with bare fingers. If bulb is touched with bare fingers, it must be re-cleaned with alcohol.
Step 11. Tighten two thumbscrews in an alternating fashion until fully secure.
Step 12. Close access door.
Step 13. Reset Lamp Hours. (Refer to Best Boy User Manual.)
