We all know the heat dissipation is important for Luminous Decay and Lifespan,for example as below photo:
The temperature difference between Green line and Blue line is around 15-20 degree,then the L70(running hours when luminous decay reach 30%) is 20,000 hours and more than 50,000 hours,a very big difference.
That’s why heat dissipation is so important,then how to judge whether the radiator is good or not?
Below is a test report of 100w high bay,Ar1 is the temperature of driver size,Ar2 is the temperature of LED size,we can see the temperature difference is only 0.9degree,which means the heat is transfered very well from bottom to top.
Only our Galaxy high bay,with Ceramic COB LED and Phase-Change Heat sink can reach this,that’s why we can declare we are with the lowest luminous decay.
