Are these bulbs OK for totally enclosed fixtures?

They do not get hot only slightly warm. Easily handled with your bare hand. LED's do not generate heat. I asked one of my techies sons how that works and they said it is two metal plates, germanium and something else. when they apply current to one of the plates, it causes electons to jump to the other releasing energy in the form of light without heat. I love these bulbs, they are brighter and use about ten percent of the current than the bulbs I replaced. I plan to replace every incandescent bulb in my home.

Absolutely OK. They emit close to zero heat. You can grab the bulb with your bare hands even after it has been on and not get burned.

If they are used vertically, the answer is yes. If they are horizontal I have been reluctant to use them as I am not comfortable they will work well.

No. Printed on the bulb itself is the text: "Caution not for use in totally enclosed luminaries suitable for damp locations"(two separate lines split between luminaries & suitable. It is not clear to me if this means it can be used in damp locations or not, but definitely not in enclosed lamps.)

IMHO these are the best Led on the market, by far. I would be careful using these bulbs(any Leds) in an enclosed lamp. All Led manufactures warn against using Led light bulbs in enclosed lamps. They can over heat, and shorten the life span of the bulb. The other issue, all Led manufactures warn against using Led light bulbs outside. Unless it states the bulb is for outside use, be careful. I hope this helps you.

I'm not am expert, but I don't see why not. Especially if it will be enclosed. Led lights are not affected by temperature swings like CFL bulbs.

This depends on the dimensions of the fixture. I noticed that the bulbs are roughly the same size as a standard 60w incandescent bulb so if you used one of these previously you should be fine.

Two of six that we placed in a single bulb outdoor enclosed fixture burned out in less than a week. The packaging does not say you can't use them in enclosed fixtures unless you are using them with other types of bulbs in the same fixture. YMMV

I'm not sure but they don't get overly hot so it would be ok for those fixtures .

I don't think so, because it would need to be protected from direct moisture I'm sure and one of the provisions for use states it cannot be used in enclosed fixtures.

I have used them in all the fixtures in my house for months now, dropped my energy bill by 20%. I have several dome type ceiling fixture that are enclosed, i have also used them outside, exposed to the weather and as of yet, they all work great. I have had one bulb out of the 20+ that I purchased go bad. If by totally enclosed luminary you mean a sealed outside light fixture, I have not.

I'll say yes, with this caveat: Like any halogen bulb these things get hot and they really should not be used in an enclosed fixture with no airflow or very bad airflow. I put these in a chandelier in my parent's house that really did not have good airflow, just a small opening at the top; and in that situation the lifetime of the bulbs is shortened.

According to the Philips LED bulb data sheet, it should not be used in a totally enclosed fixture.

On bulbs.com they say not to enclose an LED bulb because it will shorten the bulb life. Check it yourself but everything I have read on LED bulbs says not to enclose these bulbs.

The led bulbs work well in enclosed locations. Just make sure the size of the bulb will fit.They are good for stove hoods and ceiling fans because they generate much less heat.

I second what the others said. The problem with an enclosed fixture is the heat build up shortens the life of the bulb. This bulb produces only minimal heat.

The reason fixtures have a wattage limitation is because of heat. Energy saving bulbs produce less heat and more light. So you can use energy saving bulbs with even more lumens than the traditional tungsten bulbs. Look at the actual wattage used, not the tungsten equivalents. One caution though - even though LED bulbs produce less heat, they are more sensitive to the heat they DO produce. Thus the warning on some packages not to use them in totally enclosed fixtures. Since this fixture is totally open though, you can safely make it REALLY bright with the energy saving bulbs.

They are not rated for outside. The vents would allow weather to get in to the socket. You could enclose them but the stock lamp burns very hot. I have replaced the lamp with an LED par 38 and they burn much cooler. Still not weather proof but could be containable.

I have not experienced any issues with these. I have them in the home and outside. Enclosed bathroom ceiling lamps and similar have been fine.
