Are these safe to use in an enclosed fixture?

I used these in my kitchen paddle fan to maximize the light output. The shade is open on top so heat build up wasn't a problem. If you are using them to replace an incandescent bulb they should be fine. All incandescents create more heat then fluorescents so that would represent a heat reduction. If you are using them to replace a smaller fluorescent bulb in a tight enclosed fixture, logically a larger (more watts) creates more heat then a smaller one so its more conceivable that it could create more heat then the fixture could handle. A fixture with a real ceramic socket is more tolerant of higher heat. You might want to buy one bulb and see. I used these in my kitchen paddle fan to maximize the light output.

I am not a safety expert. The bulbs are big, so if it fits, the decision basis would be similar to a normal, non CF 18 Watt bulb --- from a heat dissipation perspective.

I don't why they wouldn't be safe. The use less power and generate less heat than a conventional incandescent equivalent.

Phillips says the fixture should not be enclosed. However all parts of this bulb measure temperatures far lower than a comparable 60 watt incandescent. If the alternative is using a 60 watt incandesent bulb in an enclosed fixture or this bulb, the temperatures will be much less with this bulb.

It should be ok. I use one in a collapsible light box for 3 to 4 each time and never have any issues. Just remember these are very large lamps. Here's the box we use. http://www.amazon.com/gp/aw/d/B0028K2TWM/ref=mp_s_a_1_3?qid=1396835122&sr;=8-3π=SY200_QL40

Hi, Thanks for your question. These are safe to look at, although whether LED, Fluorescent, or Incandescent the brighter the light and the longer looking can temporary bother anyone's eyes.SincerelyRockyKamrock Lights

I have mine outside, they are not a water tight fixture but they are well protected from the elements. I have not had any problems, they have been up for about 3 months. So far so good!!

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.

I use them in fan lights base up without problems, to my knowledge. I also use them in outdoor fixtures with base down.

I would install them in your application. As long as they are out of direct water contact, they are an enclosed fixture with a screw in mount.I don't recall if there was any listing or UL rating as far as indoor / outdoor/ damp location.

These fixture are safe to use in a bathroom, I instaled one over my vanity. The tubular bulbs recommended are not strong enough, I suggest you use the narrow neon bulbs or even better the LED bulbs (more expensive, but they will last a lifetime)

Don't count on it. I suppose if the fixture is well-sheltered like on an enclosed porch you'll be OK, but I wouldn't expose the bulb to driving rain. I use them indoors.

These are not sealed, and would likely corrode and fail over time. You may be able to install it in a rated fixture for showers. Refer to appropriate NEC standards for shower installations. An alternative would be an LED bulb installed in a fixture designed for showers.

The top and bottom are open so the bulbs would be exposed. I don't think they should be used outdoors but technically they can

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.

As Stair Climber said, the package says not to put it in any enclosed fixture. I have mine enclosed in an outdoor lamp post but it does have vent holes at the top. It would probably be too bright for indoor use anyways.

They say not to. I do, though. I don't know the reason why they say not to. I use them in an outdoor fixture and don't ever leave them on more than a few hours at a time, so I have not been able to check to see if there is an increase in temperature that is drastic.

these bulbs are not intended for use in enclosed can light fixtures. a statement on this is included on the product packaging

I believe these bulbs need to be in an open fixture...They can be placed in a dome fixture if it's not full enclosed.
