Which statement is true regarding handling projector bulbs?

• A. You should handle by the glass portion only
• B. You should always handle by the porcelain base only
• C. You should never handle projector bulbs
• D. You should handle by the metal base only

Answer: (B)

Handling projector bulbs is about avoiding oil contamination of the glass and preventing heat-related damage. The glass part becomes extremely hot in use, and oils from skin on that surface can create hot spots, leading to cracks or failure when powered. Gripping the bulb by the porcelain base confines handling to the non-heated, non-glass portion and reduces the risk of contaminating the lamp’s active area. The base is designed for gripping and installation, while touching the glass risks damage. If the bulb is cool, use a clean cloth or gloves to grab the base, and always handle it by that part only.
