Before changing a lamp in a studio light, what is a critical safety step?

• A. Leave the circuit breaker on
• B. Touch the bulb with bare fingers
• C. Use metal tools to remove the bulb
• D. Turn off the circuit breaker

Answer: (D)

The essential safety step is to turn off the circuit breaker to cut power to the fixture. This removes all electrical energy from the light, preventing electric shock or arcing as you handle the lamp. In studio lighting, circuits can still carry voltage even if the fixture’s switch seems off, and the breaker provides a reliable, source-level disconnection. Let the fixture cool if it was in use, and proceed once power is confirmed off. Leaving power on risks shock; touching the bulb with bare fingers can conduct electricity and heat; using metal tools can create a short or become energized. Turning off the circuit breaker creates a safe, controlled environment for changing the lamp.
