When installed in a track lighting fixture, is it better to leave off the glass cover to allow the LEDs to vent, or keep it on for more protection?

The fan is there to bring cool air into contact with the heatsink inside the bulb. If it can't intake cool air, the bulb life will be shorter--heat is the enemy of electronics. If you leave the glass cover on your fixture, can cool air still get inside the fixture?

No need for glass cover, bulb has a cover already, bulb does need venting for longer life

In other words, do not use this in an enclosed fixture or it will overheat.

The one enemy of light emitting diodes ( led ) is heat. Thus, the high lumen out put led's need to be cooled. This particular unit has a small fan located inside the base under the emitter ( notice the little slots under the translucent area of the light? ). If water would get in, the light would short out.

Pt, responding to you question from Loomis Ca. I purchased one of these glass covers for my ceiling fan a couple of months ago. I am very happy withe the quality. It should work just fine as a light bulb cover. There is a center hole to attach it to the fixture. Good luck

Actually, I'm not sure. The light diffusing cover is plastic and maybe a halogen lamp might prove too hot and damage or melt it.

I'm an engineer who designs buildings. Our lighting designers say that LEDs should not be used in enclosed fixtures, but that does not match my experience. I have 5 Besa Bobbi ( http://www.amazon.com/Besa-Lighting-911052C-Collection-2-Light/dp/B000TF9OTE ) ceiling fixtures (which I love) with two of these per fixture, and I have had no failures. I think it is a heat transfer issue. If the fixture were only rated for a 20 W incandescent there might be overheating, but I think that any fixture rated for 60 W lamps will not overheat with 9 W LEDs. I even have one marine light using these on a porch.

If you have a mesh top. Cover your top with aluminum foil. It will help retain heat. If not get a bigger bulb and bigger fixture. I stopped buying these because they only last a month or two until they blow out. The element melts to the copper conductor inside the fixture. No problems with the outlet it was plugged into either, the house in only a year old.

No, leave plastic off. Do not touch the bulb. Use a towel or clean rag if handling.

While they will work in an enclosed fixture, be aware that their life may be shortened. The electronics in an LED bulb are sensitive to heat. Even a modest rise in ambient heat (such as trapped in an enclosed fixture) will cause the electronics to age more quickly than when there is air circulation to keep them at room temperature.

I would just buy a cool tube light and call it good. Its a bit too narrow to let an HID light free hang in there with no cool tube it will get hot quick anyway you'll at least a 6" inline fan for proper venting even with a cooltube.

Most LED bulbs should work as long as they're not much larger than a regular incandescent. Only possible problem I can think of is overheating. It's fairly sealed so the heatsinks on some bulbs won't be very effective which could reduce the life of the bulb. Some LEDS warn against using them in enclosed fixtures for this reason. The fixture can also be used just with the metal cage without the glass dome which would allow airflow while still offering some protection.

You don't have to, but it can get in the way. You have to wire around them if you leave them in the fixture. Hot to switch to red on led, black out of led to ground, all assuming you have 12 volts feeding your fixture.

The back of the box says it is not suitable for completely enclosed fixtures. Due to heat, most LED bulbs will have reduced lifetimes if they don't have some ventilation.

I agree with the other 2 answers. This fixture also has very little rim space so you don't have allot of wiggle room. LED technology is so nice because you don't have to worry about heat buildup like you do with other light sources.

I bought a track light kit from a big box store. The led lights were removeable. We were able to put them on an existing track that previously had powered halogen bulbs.

No, the heat from the bulbs is dissipated through the screen. It would be a fire hazard if removed.

Very careful twist the light cover or to be extra careful, just go ahead and twist the whole thing off the ceiling. That's what I did to ensure I didn't break the glass.

Masking around the light is a good idea as it provides some protection if you lose control of the drill while resurfacing the light. I did just use painter's tape.
