My outdoor halogen floodlight with a "dualbrite" sensor

Customer Question

My outdoor halogen floodlight with a "dualbrite" sensor needs to have the connections redone often, I tried using some dielectric grease on the wires and the bulb ends to no avail. Any ideas?

Hi, I'm Mike G and I'll be glad to assist you. When you say it doesn't work, do you mean it won't turn on, won't turn off or what? Does it come on and stay on when set for test?

Customer: replied 1 year ago.
it won't come on, but on occasion it would work a day or two later.
Customer: replied 1 year ago.
if I rewire it and do the test it works as it should, but when it stops working even in test mode it won't come on

Do you check the voltage with a 2 wire tester when it doesn't work? Is there a switch for the light? It probably is a voltage problem ahead of and feeding the light, if you have replaced every component.

Customer: replied 1 year ago.
it is on a switch. I have't checked the voltage, but it always worked when I rewired it

The factory strip on the fixture wires is always to short for a good connection. The stranded wire has to lead the solid wire into the wirenut. The proper size wirenut is also a possibility for it failing.

I thought maybe different nuts might help. The wiring is single copper and fixture is stranded silver in color. I used the grease because I thought might be caroding. is there a certain type or size nut I should use?

I like the Ideal Twisters. A tan colored one will work.

I'll give that a try and see if it works, Thanks

If it should not come on, test the wires for voltage.
