    Heat generated by concrete?

    Ultra low temperature lighting

    Does anyone know of any LED lighting that can be used at -50°C?  It seems most manufacturers only test down to -40°C.  We are currently using incandescent bulbs in our application, but the heat and electrical loads are pretty large.  I'm sure somebody in Alaska has used some for outdoor lighting...

    Silence button with timer

    Hey guys, please bear with me since I'm an ME trying to figure out circuits. I'm working on a control panel with a 24V alarm buzzer.
