Both LM79 and LM80 are methods for measuring the lumen. The simplest way to tell the differences between LM79 and LM80 is that LM79 is a method of measuring lumen for a whole luminaire, such as a bulb, a high bay, while LM80 is a method of measuring lumen only for LED, which is called “LED Chip”.
On the Illuminating Engineering Society of North America (IESNA), the test content for LM79 including:
1. Electrical parameters (power, voltage, current, power factor)
2. Color parameters
3. Luminous flux and light effect
4. Light intensity distribution
5. Uneven chromaticity
On the Illuminating Engineering Society of North America (IESNA), the test content for LM80 including:
1. Luminous maintenance rate of the light source at different temperatures
2. The chromaticity maintenance rate of the light source at different temperatures
We can provide both LM79, LM80 for our products. Except the mentioned LM79 and LM80, we also applied CE, CB, ENEC, UL, FCC for most of our products. It will be a great help for winning projects.
