WebAug 18, 2015 · The TM-21 publication is an approved method for estimating an LED light source’s lowered lumens as the LED is used over time. This would allow a manufacturer to estimate the amount of L70 hours for an LED light source. Specifications for LED light sources should state that LEDs shall be tested per IES LM-79, LM-80, and TM-21 … WebAn LED (light-emitting diode) is a semiconductor device that emits light when an electric current is passed through it. LEDs are typically made from a material called gallium nitride (GaN) and can be used for a wide range of applications such as indicator lights, displays, and lighting. They are known for their long life, low power consumption ... WebMay 2, 2024 · Another reason the test might not work is if your LED requires a high current (relative to standard LEDs) or has voltage drop greater than the DMM can supply.
