Will IES data change after the LED lights work a long time?

IES parameter is different from Lumen.It includes more data for LED light,include:Light Distribution,Light Intensity,Beam angle,UGR,etc.These are very useful for lighting project designers. And We already know:for good quality LED Lights, the Lumen reduction is very small after working for years. So,a question come:After the LED lights working for a long time, will these IES parameters […]

Same IC, Different Temperature?

FCS found the interesting phenomenon during this week’s test.   1. There is unequal heat distribution on LED High-Bay’s housing M1 (Point 1 on the housing): 49.1°C   M2 (Point 2 on the housing): 43.8°C   M1 > M2 (more than 6°C)   But why there is unequal temperature on the housing. Let’s open the […]
