How to choose one better led street light?
Don’t believe you eyes, but
temeprature

. The lights of different core-tech can cause different Luminous Decay. Our CORE-TECH is the key to solve the problem on optical loss of white light emitting diode (LED).
As is known to all, alluminum alloy is the best choice of heat dissipation.
If use die-casting alluminum, light body temperature will keep more than 60°C.
But,
our light body which is also the heat radiator made of stretch formed alluminum alloy will keep the
temeprature
only

38°C
, which will directly lower light decay, and prolong the lifespan of LEDs.

When using other led lights ,after 300~500 hours of operation the luminous flux of LEDs is 70% of initial levels.But
after 10 years of operation the luminous flux of our LEDs is about 90% of initial levels.

That is to say, after 3~5 hrs of operation ,which lamp body is 60°C is bad lamp.
