The correct handling method for projector bulbs is to handle them by which?

• A. The glass bulb
• B. The metal base
• C. The cord
• D. By the porcelain base only

Answer: (D)

Bulbs like this have a delicate glass envelope and a porcelain base. Oils from your fingers on the glass can carbonize or form hot spots when the bulb heats up, leading to premature failure or reduced life. The base is the part designed to be touched and handled; it withstands heat and provides a secure grip. Handling by the porcelain base only keeps the glass clean and intact and reduces the risk of damage. Always power off and let the bulb cool before handling, and avoid touching the glass, metal base, or cord.
