are these bulbs designed for fully enclosed light fixtures?

No, the box is very well labelled and clearly states that it is not for use in enclosed luminaires: "USE IN OPEN LUMINAIRE ONLY." That said, the lamp itself says "NOT FOR USE IN TOTALLY ENCLOSED LUMINAIRES," which just confuses things by adding the "totally" bit. It claims to be dimmable, but I have not checked it for flicker (a common issue with dimming LED lamps).

I think they would work just fine. The only problem I could foresee would be the unattractive gray base that these types of lights have, but if the light is opaque, it works. I have one in my fully enclosed opaque front porch light.

For liability purposes, I doubt if any manufacturer would recommend any bulbs for enclosed fixtures. I have tried 13w (60w replacement) bulbs in enclosed fixtures, without noticeable heat buildups). I wouldn't even think about it in locations that were "on" continuously.

I don't have any experience with these lights in outdoors fixtures, but they look pretty well sealed and I wouldn't expect a problem in an enclosed fixture.

when i read the manufactures directions on the package it did not say it could not be used in fully enclosed fixtures it just stats not to mix different bulb types such as cfl in the same fixture

None that I am aware of at present. I installed my Full Spectrum Light Bulbs (ALZO 45W CFL) in light sockets without a globe or shade (not my original plan). Used in this fashion they throw a lot of light as long as you aren't too concerned about appearances.One is mounted horizontally and another vertically. Both have been in service since the beginning of this year without any problem.

Yes. I have them in multiple fixtures that require the bulbs in that orientation.

specifically the base does get hot to the touch but it seems very little if any heat is given off. There's nearly no discernible heat from the bulb/light and almost no heat given off in general. Should be completely safe for fully enclosed fixture.

I ordered this lightbulb over 6 months ago, and it's in an enclosed fixture. So, yes it works in an enclosed fixture. At least it has for me.

Yes. It is designed for use in open fixtures. It's not suitable for totally enclosed fixtures. Not enough air flow will shorten bulbs life. Bulb has 6 year warranty.

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.

Make sure you follow the instructions that come with the bulb. Many CFLs are not suitable for enclosed fixtures (such as glass globes where there is no ventilation to dissipate heat). I've installed CFLs in an enclosed ceiling fixture and the CFLs failed in less than a year. But the CFLs that I installed in lamps with open-air lampshades are still working after several years.

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.)

It will work in a fully enclosed fixture but does not have to be fully enclosed

I would think so, I've used them in enclosed and non-enclosed fixtures with no problems.

They did not work for us in single bulb outdoor enclosed fixtures. The package states, "Do not use in multi-bulb enclosed fixtures together with other bulb technologies...". It does NOT say not to use them individually in outdoor enclosed fixtures. In fact, is also says "Suitable for damp locations but not for use where exposed directly to weather or water.", which seems to imply that enclosed fixtures are preferable. Unfortunately, two of the six bulbs we installed burned out in less than a week. I replaced the rest and will use them indoors. Hopefully, they will do better inside.

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.

Yes. They're regular light bulbs and can be used in appropriate light fixtures. Just ensure that your fixture is rated for outdoor use.
