LM-79 test

1. Introduction to LM-79 certification

IES LM-79 is the optical and electrical measurement method for solid-state lighting products.

Note: Solid-state lighting products are defined in the standard as using LEDs (including organic or inorganic LEDs) as the radiation source, and the light emitted is products for general lighting.

2. LM-79 certification test scope

Solid-state lighting products based on LED technology include control circuits and heat dissipation parts, so the products only need AC mains or DC constant voltage power supply to operate.

It is not suitable for solid-state lighting products that require external control circuits or heat sinks, such as LED chips, LED packaging products, and LED modules.
