Can this bulb be used in a parking lot pole light - its a completely sealed for waterproofing but my concern is the heat dessipation

I can not say for sure but I would recommend against it. The light has a built in cooling fan and I expect the sealed housing would cause it to heat up.

This light runs very hot. So hot that it needs a cooling fan to make sure the LED doesn't fail. If the lamp is installed in a sealed housing it will cause the light to overheat quite quickly. But, because of the fan, you also don't want this lamp installed outside unprotected, as rain and moisture will also damage the LED and cooling fan.

From what I've used mine for it does get fairly hot when it gets enclosed. Given the built in fan it probably would be a bad idea.

NO, do not use this in parking lot heads or even in globes or acorn style fixtures!!! The fixture runs too hot and needs to cool, enclosing the bulb will cause it to burn up. I have had this happen and highly advise you do not use it in this application.

I think so. It sticks pretty well and mine live in the garage in Florida where it gets pretty hot. It's actually a really clever idea because unlike a regular trunk light you could move it around. I might get one myself for that purpose.

These are meant for open use in a chandelier, which is how I have been using them. If they were protected there should be no problem with using them outdoors. They are good bulbs.

It says right on the neck of the fixture NOT FOR USE IN ENCLOSED LUMINARY. Many commentators stress how little heat comes from these bulbs. That is true on the lighted side. The backside or the side in the enclosed can is another matter. If you feel the backside cooling fins you'll soon realize that plenty of heat is generated, so much so that inside an enclosed can they'd be too hot to touch. That is undoubtedly the reason for the disclosure stated in the first sentence. What is at issue is the build up of heat. Will it trip the cutout? Will it affect the electronics that make the LED function? I have these same lights in enclosed cans in my house. For years I had halogen in the same cans. The cans are rated for insulation coverage. At the very least I'd expect a drop in life expectancy. It'd be nice to have a little vent in the can to vent the heat.

Indoor or outdoor use primarily depends upon moisture resistance, and Philips has indicated that this packaging cannot resist moisture incursions. My (in-expert) thought is, if you use non-rated electronics outdoors, you are obliged to assure yourself that it will not be exposed to moisture. That can be achieved through packaging (eg external rated enclosures) or a protected location. As always, buyer assumes all risks for non-rated usage. One other observation -- I use a standard indoor-rated incandescent 100w light bulb in an outdoor fixture, and for whatever reason these bulbs have about 1/2 the life of the same bulbs used indoors. Given the expense of an LED lamp, this might be a consideration. I note that weatherproof rated par30 led bulbs can carry a premium, as here http://www.amazon.com/Lifetime-Lights-PAR30-Waterproof-Replacement/dp/B00D4YUABI. On the other hand, this PAR38 weatherproof appears affordable, as here http://www.amazon.com/Feit-Electric-Dimmable-Weatherproof-Outdoor/dp/B00ARKIP5U. Hope this is helpful.

I dont think so, seems to be as stiff as a hard taffy. My lights remained sealed through the last year, with all the temperature fluctuation it must have a bit of pliability.

This lamp does not have an all weather enclosure, but if you place it in a protected area, it should be fine outdoors.You will need the proper socket for it to work.

The lamp is not protected against moisture, so my guess is that it probably would be risky. My application was in a lawn tractor which is stored in a garage and so has no serious moisture exposure. If the outside fixture is well sealed against moisture, it may survive. If you want to gamble less use one of the LEDs which are completely enclosed in the glass or plastic "bulb".

It is not recommended to use the light in enclosed fixture not due to safety but due to the impact on lifetime of the lamp. LEDs do not like heat and depending on the heat generated in the application, the hours of usage, the life of the lamp may be shortened. The lamp features over temperature protection. In the event the ambient temperature of the application gets too warm (exceeds 45C) the lamp will dim down to allow it to cool off. Replace and forget!

Nowhere on the packaging does it say it's safe for outdoor use. Based on that, I would not recommend it be used anywhere it could potentially get wet. I live in Arizona and mine are installed outside facing down under a covered patio. The chance of mine getting wet is minimal, but it is still possible. It was a risk I was willing to take. To supply further information: I installed these on the back patio to be used with a dimmer. The dimmer I am using is a GE Z-Wave dimmer. The lights do not want to come on using the dimmer switch. I have to turn the dimmer switch on (at which point they don't come on), then turn on the slave switch in the 3 way switch setup, then hurry and turn the dimming down on the switch or the bulbs will turn back off. I am going to try some Phillips bulbs to see if the same problem exists with the. Using standard switches, this does not occur and the bulbs are excellent.

Hello my friend Philip,Frankly speaking, I would not recommend you to install this downlight outside. As you can see, it is not waterproof , nor weather-proof.So pls kindly install it for indoor to maintain the downlight a long using lifespan and a good working condition.Any question, pls contact Lemonbest freely, as we're always here for your help.Nice day.Lemonbest

I know this is an old question, but I've had one in our pole light which is inside a fixture of course, but still completely outside. It's worked for over 2 years in -25ºF weather and 100ºF+ weather so I would have NO problem suggesting these for use outside as long as they're not open to the elements. Best 10 bucks I've spent! I now have 5 of these and not one failure.

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.

Hello. If there is some ventilation there should be no problem. But using a complete sealed fixture (like IP65), this could overheat the bulb. Your technolamp Team.

I don't recall anything on the box that about that. This bulb only goes into special fixtures. So if the fixture was made for exterior use I would think it protected the bulb. A previous poster mentioned using a dusk to dawn timer. Those are often used outside. But it is a CFL and low temps are a factor in light output until the bulb heats up.

i'm guessing not because it comes with a plug.. but it does say 'suitable for wet locations'...??? the light bulb doesn't appear to be fully sealed by it's cover.. i keep mine on a porch.. sorry.. not sure...

I don't see why not. There is VERY little heat produced by the bulb. I used this in can lights on a boathouse pier.
