    Erika Riley - Burned lights

    My hardwired underwater pool light keeps burning out. I put in a new bulb, works great for just a couple months (with very little use even then) and they die. Breaker is working, toggle light switch is working. Doesn't seem that this lightbulb should have an extraordinarily shorter lifespan than any other bulb? They aren't all that easy to replace either! Anyone have a trick for that too??

    What is the make and model light fixture and the bulb you are using?

    When you replace it do you replace the gasket also? Has there been water in the fixture?

    Is there a GFCI on the circuit?

    How old is the fixture?

    Have you opened the junction box and made sure all the connections are tight?

    these are very different beasts compared to normal incandescent light bulbs- they work in very overloaded mode 'assuming' the water is always present around its enclosure. It will simply burn out if you turn it on outside of water.

    Short to ground would trip the gfci.

    What exact bulb are you using?

    Measure volts and amps at the junction box to see what that shows.

    What light do you have (make model)?

    Regular floodlights won't survive in a pool fixture, Try a bulb rated for use in a swimming pool fixture, They are different.

I think the practices regularly espoused on this forum (especially the BBB method) are outstanding; however my comments will be often oriented towards the goal of getting it done, and getting it done right now!

    Does the light fixture show any signs of damage (corrosion, melting etc.)?

    How old is the light?

    IMO, this is most probable cause- use of a bulb not rated to be installed in the pool light.
