Re: Motion sensing security lights
My electrician suggested a model that escapes me now, from a electrical supply house in town [call one near you?] -- his reasoning was that they actually hold up. Seems to me they were OVER $100 though, and I can get cheapies as low as $6 or so on sale at a Wisconsin-based lumberyard on sale. Most of these need a current path through the bulb filament to work, so flourescent is kinda of out, plus those get so dim below zero -- so LED or incandescent loads would be needed. I use outdoor units INDOORs in basements and such, and attach 1-2 40" shop lights to them [which WILL NOT WORK withOUt having also a small appliance bulb or something hooked up in parallel!]. Edison-based LED unit MIGHT work, but until I get mine from Quickar I won't be able to say. The issue is, of the incandescent burns out the flourescents will pulsate on/off in a way that seems unhealthy, until you discover the problem or something fries. Hmm, so I don't think I quite answered your question.
I DID stick a $20 unit out in the elements last year and it's still working, though I did seal it up well and spray WD-40 a few places.
