If so, will they still be cheaper to operate? I can buy that they'll still use less energy on net, but that isn't the only concern here.

- wildwood 17y agoIf the heating element is thermostat-driven, and not on all the time, then yes.
- ars 17y agoHopefully not a thermostat but rather a proximity or a frost sensor.
- evgen 17y agoNo, use a thermostat. It is much simpler, less prone to errors, you only need one per light housing, and the energy cost required to keep the shrouds above 34 degrees is quite insignificant.
- pavel_lishin 17y agoYou could probably get away with having one per block; aren't most traffic lights all connected? Or have I just been watching too many movies where hackers take over streetlights?
- evgen 17y agoPutting one per light housing means it gets added at the manufacturer and you don't need to do any additional wiring or setup at installation time.

- aplusbi 17y agoPresumably they wouldn't turn the heating coils on in the winter.
