How do you measure temperature in a light bulb?

To measure the temperature in a light bulb, you can use a digital thermometer with a probe that can withstand high temperatures. Insert the probe carefully into the base or glass of the bulb, ensuring it does not touch any electrical components. Alternatively, infrared thermometers can be used to measure the surface temperature of the bulb without direct contact. It's important to take readings after the bulb has been on for a sufficient time to reach its operating temperature.
