When relamping a fixture, in which direction does the nipple on the globe point?

• A. Toward the Reflector
• B. Perpendicular to the Reflector
• C. Away from the Reflector
• D. Upward

Answer: (C)

Proper relamping depends on how the globe’s mounting nipple is oriented relative to the reflector. The nipple should point away from the reflector. This placement keeps hot air from the bulb moving away from the reflector, reducing heat buildup on the reflector surface and helping prevent discoloration or warping. It also provides clear clearance so the globe can be removed and reinstalled without the nipple hitting or catching on the reflector, which protects both the fixture and the globe during maintenance. If the nipple were toward the reflector, heat and contact risk increase, making removal and re-lamping more difficult and potentially damaging the reflector or finish.
