How does the type of bulb used affect snow accumulation?
- andai 7y agoIncandescent bulbs produce a lot of heat, melting the snow. LEDs run fairly cool.
- StavrosK 7y agoAh, didn't think of that, thanks.
- Yizahi 7y agoPowerful LEDs also run rather hot, more specifically their power circuits. My pocket size flashlight would easily run up to 100 degrees I think but it has protection built-in and steps down brightness when overheated. And it only has 1 LED and 1 lithium cell for power. So it probably would have been easy to design external radiators for traffic lights internals, with a heatpipe or similar solution. But they would be more expensive that way.
- severak_cz 7y agoLED light does not produce enough heat to melt snow like old light bulbs.
- thesmok 7y agoMy bathroom mirror is LED-backlit. Old halogen-backlit mirrors do not fog because they get warm. When ordering my LED mirror I had an option to get it with a heating element built in. They just glued a heating film on the back of the mirror, and my mirror is not fogged after showering.
