If you still have the proof of purchase and you paid it with your credit card, I’m sure HomeDepot can pull up the purchase transaction and print out the receipt. 2nd, I haven’t been in this situation before. I’m sure Cree company will issue a replacement bulb for as long as you have the proof of purchase. Don’t quote me on that. But you can at least try and talk to them and go from there.
To my knowledge, there is no warranty on these light bulbs.
Probably not. It has a candelabra base which is much smaller than the bulbs for my particular range hood which takes a standard lamp bulb base.
The problem is likely caused by the switch that runs your lamppost. Most dusk-to-dawn- sensors are NOT compatible with LED lights. There are some switches that are, but unless you've replaced that sensor very recently, it's most likely not. Try the light bulb in another light/lamp in your house that is not on a sensor or dimmer.
No. If you need a connected bulb, you will either have to buy a different one or install a connected adapter in line with the bulb.
I live in northern Florida, and have about a dozen of these in outside service. Outdoor fixtures are designed for use with incandescent bulbs because they are cheaper. When U.S. laws started phasing out sale of incandescent bulbs with the normal base, fixture manufacturers circumvented the laws by using candelabra base instead. Because incandescent bulbs are so much less efficient than either compact fluorescent or LED, the fixtures have to be designed to reject the heat produced by incandescents. That's why fixtures have a sticker with the maximum Watt rating of bulbs to be used. For the most part, you may ignore those stickers when using LED bulbs because they run so much cooler. I can't comment on how well the TW bulbs would work if used in sub-zero weather. We don't get those temperatures here in Florida--the coldest weather my bulbs have seen is around 25 F.
The bulb diameter, width, and depth is 1.4 inches. It's 4.15 inches high.
Yes and since the are led, they are much cooler than incandescent bulbs.
I have nine of them installed in enclosed outdoor fixtures beside my garage doors.
Yes, but they are slightly longer than standard incandescent bulbs, so be sure the bulb has a bit extra space.
