Dave Your question is an oxymoron, or at least a contradiction of terms. All the coach lights with integral motion detectors and or photocells are of Chinese mfg. and subject to work until they quit. Lightning arrestors at the panel help, 130 volt bulbs help, but a remote mounted, domestically mfg. photoocell that is not pointing at the sun is the most practical solution. Photocells are light sensitive(Duuuhh!) devices and the fine print suggests not placing them on the sunny side of the structure. The fixtures that contain the devices offer no protection or warning to the installer that sunlight will cause the pc to fail.
Any way possible you could install a separate photo-eye to control the coachlights? That way you may have any fixture of your choice, and if the photo eye that you install elsewhere fails, you can replace it without replacing the entire fixture.
Thanks guys, you're sort of telling me what I already knew. My client is having ongoing problems with cheap photosensor lanterns. I told her a real photosensor probably costs more than the lantern, so how good could its photosensor be? I told her I could rewire them to a quality photosensor and she said no. I was just curious if anyone made a lantern with a quality photosensor.
I have a pair of home depot Coach lamps by my front doors, worked well for almost 5 years, but my front door face's east. Well they did work well, until my roommate had the new Boyfriend pressure wash the house while I was at work.... He Pressured washed one of them and it no longer works, but the other one is still going strong. If your client is having alot of problems I would go along with the remote photo-sensor on the north side of the house. or possibly a timer.
Sounds to me like the customer here is having a difficult time understanding that her light fixture w/ built in photo sensor is a piece of crap! I always have a hard time explaining that gracefully. Add into the mix that it was built in China and that helps explain alot.
