LED to shoot the light, heat sink, aluminum alloy profiles and die casting aluminum radiator which is better?
Even better aluminum profile, material, wall thickness can be thinner, heat dissipation performance is better..
LED lamp is not hot cold light source, isn't it. I use this is out of the blue ball bubble lamp will not hot
Profile of the general than die-casting aluminum is better, but now there is a cold forging is also good, but I still want to see the structure whether reasonable!
