Sounds like you probably created
a loose connection in one of the junctions you opened to install the fixture. I would check for power at the switch location
and if that's OK, then you may need to remove the light fixture to check for power there. Since that is the only area
you disturbed (?), that would be my first place to start looking.
Why does my ceiling fan light blink on and off after I turn it off?
Is your ceiling fan light operated by a remote control? It might be just
a quirk with the brand of fan you're using - especially since there are no other lights experiencing the same problem. If
you still have the instructions for the fans, you might find some answers in there.
recently built a lamp. I want to run the wire from the fixture to the base through copper pipe. Is there any danger in using
Technically, you are supposed
to use only parts listed for that particular purpose. Copper piping is not considered a listed component.
Without seeing the lamp, it's hard to
tell what you could use. Ideally, threaded lamp pipe works well, or you can use any of several other types of conduit such
as EMT, IMC, RMC, ENT (if not needed to support the weight of the fixture) or even electrical PVC.
With regards to grounding, any exposed metal part on the fixture (frame,
pipe, or otherwise) must be bonded to ground to divert any fault current that a user could inadvertently come in contact with.
Lately there has been a ceiling light in my house that keeps blowing bulbs. Why would this happen so often?
Premature bulb failure can be caused by a multitude of reasons such as
power surges, loose connections, or vibrations.
make sure that the light fixture in question isn't being affected by movement, vibration or other motion (such as flexing
floorboards on a floor above the light). If there are loose connections within the fixture, it can magnify any vibration problems.
Also, if the light is part of a ceiling fan make sure that it is not wobbling. A light bulb suited for fan use would also
