melted light cover in shower
 
we just bought a house and my husband left the shower light on overnight, the plastic cover melted, we don't know the manufacturer and don't know how to go about replacing it, what should we do? Is it safe to take a shower without a cover? How can we cover it temporarily until we find a solution? Thank you! Julie

Look on the side of the can, where the bulb goes. Are there any model numbers?

How big was the bulb in there?

Is this a recessed light? If so, the lighting fixture should have a thermal cut-off that turns off the fixture if it overheats from the bulb. Either your fixture doesn't have one, or it failed. I'd be cautious about using that fixture again.

If it's a flush mount ceiling fixture, I'd double-check to make sure that it is UL-rated for wet locations, otherwise, it should not be used in the shower.

If you can disconnect the power supply to the fixture, you should be able to use the shower without a cover intact, but I would not use the shower with an open light can or flush-mount fixture that is energized.

If you have attic access over the shower, I'd replace the light fixture with an IC-rated recessed can that includes a thermal cutoff and an approved shower trim ring rated for wet locations. A thermal cutoff should prevent the fixture from overheating. If you are really spooked about it, you could replace the lightswitch with a countdown timer that would automatically shutoff the light.

Whatever you end up doing, make sure that light bulb you use is does not exceed the rating of the fixture (usually 60-watt incandescant for totally-enclosed fixtures).

Agreed!:)

I am not an electrician, so what I say below is my opinion:

If you were installing a new light I think it would also be required to be protected by a GFCI (either at the breaker, or just downstream of a GFCI outlet).

If I were replacing the light I'd find a way to get GFCI protection as well, either by replacing an outlet upstream, re-wiring, changing the breaker, or combo GFCI/switch which I believe this is.

Wow, quite a bit of misinformation in this thread. I wish you guys would state what is opinion and what is fact, and that your opinions are not based on professional experience. Sorry, EE's are NOT electricians and the relation to construction electric is marginal at best.

An open recessed light is code compliant in a shower and only needs to be damp location rated, as most are.
A recessed light that is subject to shower spray must have a wet location rate TRIM.
A recessed light in a shower does NOT require GFI protection, unless the manufacturer specifies it, and almost all do not.

See NEC 410.10(D) for more information.

Sorry, you're right, I'm not an electrician... going by what I was told by my electrician.

He said that all lights/fans/switches needed to be protected by GFCI in the bathroom, and told me the common sense thinking was that anything you can potential touch from within the shower by reaching out of it--like a light in the shower, or wall switch with a few feet--must be protected.

If that's mis-information then I apologize.

FWIW, the fixture in my shower is a fan/light combo, so maybe that changes the requirement vs. just a single light.

Even if not required, would you agree that GFCI on a shower light is not necessarily a bad idea?

Well, a lot of guys, even seasoned electricians, still go by "what they were told" and not what is fact or accurate. I know some guys that have been in the trade for 30 years and don't even own a current code book. Sad really.
If a shower light is installed properly there is no danger of touch potential.

That actually does change everything. Most bath fan manufacturers DO require GFI protection when FANS are installed over tubs or showers.

It's not a bad idea, just unnecessary. If it makes one feel better than have at it.

if you don't want to plastic melt again put a cfl bulb instead if possible

Question: when would a recessed light can installed in a shower not be subject to shower spray? I can understand a bathtub without a shower head, but I would expect that any can installed in a working shower would be potentially subject to spray.

Every can I have seen is rated for damp locations, but specifies that a wet-rated trim be installed if the light will be directly over a shower. I've never seen a can specify GFCI protection for installation over a shower(although most fan/light combos I've seen do require GFCI if they will be over the shower).

That being said, I've never been big on putting bathroom lights on GFCIs. Nothing more fun that fumbling around in the dark...

Thanks for straightening me out.

I've never seen a regular shower head that aimed straight up. :whistling2:
