Can I use this bulb with an outdoor fixture that turns on at dusk and goes off at dawn?

i have been using several of the Philips led bulbs above and have had good luck with them. They are rated 'wet location' but some led flood outdoor lamps are rated 'damp location' which is not as high a rating for outdoor use with the possibility of direct rain.

Most likely. There may be some dusk/dawn controls that pass a small amount of current through the lamp, much the same way some electronic incandescent dimmers do, that don't work properly with CFL/LEDs. Not knowing what model the dusk/dawn control is, your best off trying it to see if it works. Only other concern would be whether your fixture has a shroud, and if the lamp will properly fit in it.

Yes, I use it in exactly that application. It doesn't rain much in my area, but I trust the claims that the lights are weatherproof.
507006
Yes. Not only that, but the bulb also works on a lower brightness for background, nighttime use and full brightness when tripped by a motion sensing light fixture. I did the math on these bulbs. They are expensive at first, but based on the rate we pay for electricity (14 CENTS PER KILOWATT HOUR), if the bulb lasts 1.8 years, it pays for itself in our region

I just got a second one of these for my house yesterday and the back of the package says, "This lamp is not compatible with photo controls, occupancy sensors, or timing devices." So while others are reporting that it will work with their setups, it appears Philips does not recommend it for this use (dusk to dawn fixture).

Should be able to. Only problem with the automatic switches sometimes is if the bulb were fluorescent, and these aren't fluorescent.

Yes, I use this as an outdoor motion-sensor security light and it is very bright and seems that it will last a very long tie.

Funny you should ask about "always on". I bought and installed two of these. One is on all the time dawn to dusk no matter how I have it set. The works sometimes and others it is also on dawn to dusk. I do NOT recommend these lights.

I have this installed in a fixture that is fully open to the elements but it is covered by my patio. As a CFL bulb, they are not recommended to be in completely enclosed fixtures so I would imagine it is okay as long as it is not open to rain and heavy wind.

This fixture does have a night and moon glow feature that would be not as bright as the daytime bulb. The daytime bulb is not dimmable.

Hi Becky, I have not used for outdoor use so I am not sure. Follow the maximum wattage and maximum voltage for your fixture, it should work unless it is exposed to the elements, rain, etc. or go back to your fixture company customer service, ask them for help.

It will work fine in an outdoor fixture that opens at the bottom (as long as it fits in the fixture OK). You may want to confirm that the bulb will fit (length mostly) in this application. As others have noted it's a bit long. I have a couple of them in fixtures that are completely wide open so it's of no consequence in my application. Just be sure to confirm that the overall size (width and length) are fine to fit inside the fixture. As far as it the bulb itself working in the fixture, yes it'll work fine. I really only think you'll run into an issue with fit. If it fits, you'll be good to go. It will work fine in an outdoor fixture that opens at the bottom (as long as it fits in the fixture OK).

Mine are used in a fixture that uses a photo sensor to turn it on automatically after dark. For such an application, the answer is "Yes".

No, I don't believe it can be used for dusk to dawn lighting. Mine only comes on when motion is detected.

As long as the fixture is rated for a 100 Watt Incandescent, you'll be just fine.These instantly emit a brilliant 1700 Lumens - perfect for outdoor. Bad part is the relatively short 750 hour life. "Double life" bulbs last longer, but you lose a few hundred lumens.

The bulb will work in any standard socket, but make sure to keep it dry. As for light output it has a decent throw even for outdoor use.

i had several dusk to dawn, utilitech lights that only lasted about 2 months i used housing and drilled a 3/4 inch hole and wired that up with same socket, has worked over a year now with one bulb

You can but because if the fluctuation of the dynamo it will cause a shortness in the lifespan of the bulb the installation instruction advises NOT TO turn light on and off in short period of times so I would advise not to you'd be wasting your money

If you want to use a dusk to dawn light, you can. You may also switch the light off, and on from your inside switch.

Yes it can be. Just put a switch in the normal way. Or you could rewire it inside and bypass the dusk to dawn feature.

I don't see why not. They appear to be sealed like any other light bulb on the market. So long as there is shielding from direct rain fall (as in a standard outdoor fixture) it should be fine. The only issue may be the light output. Generally outdoor lights for usable illumination are rated at 100 watts while this bulb is rated to replace 60 watt incandescent bulbs. It is still a bright light and perfect for indoor use or perhaps as a porch light, but as an area light for outdoors you may want something with more output.

yes, it will work . the bulb can be used in both outdoor and indoor setting as long as its in a full or semi closed enclosurecheers

No I couldn't depend on two of them to operate landscape lighting from dusk to dawn! Sorry that was my experience.
