Question: Is it true that this bulb is not UL listed? Sounds dangerous, if not UL listed. Also: Does bulb really last long before it burns out?
Document: I am suspicious about how long this bulb will last because it gets really hot. I am not used to that with LED lights. It does have a good quality of light but I would feel better about it if it didn't get so hot.
We installed light bulb in our living area in a low hanging single globe light fixture (on long chain hanging over a table). The light out-put was quiet a bit better than expected. It gives a very nice bright (also wide angle) but warm light, We are very happy about the light quality.
The warm white has the same color and feel of a standard incandescent bulb. It's just above 800 lumens so it compares well with a true 60W. No humm, the light comes on instantly. So far so good. Minus 1 star do to length of time installed, we will see if the product last more then a month as many LED's have overheat issues.Update: I've had these installed for almost a month now, and simply love them.
Surprised how bright these are. I brought them specifically for their long life as the location I need them for is very difficult to change the bulb. Hopefully these will last longer than me so I'll never have to replace them again :)
I believe this is brighter than 60w incandescent bulb. I installed 2 on in my living room. Very bright. If it last long, that's perfect.Some reviews told me it was noisy, but I did not hear that. I do not use them with dimmer. No buzz.
Equivalent to 60 watts , this bulb is good for reading in my favorite chair.Typical of LED & CFL bulbs, it doesn't play well with X-10 lamp modules, so I haven't tried dimming it yet.The bulb appears well made and is a little heavier than incandescent bulbs - it should last a long time.The base does get quite warm, but not nearly as hot as an incandescent bulb..
The Amazon bulbs arrived quickly--but so did another box that contained some other person's order that unaccountably got addressed to me. So I'm getting the impression that there may be a certain amount of flakiness in this operation--but the bulbs are great! I hope they last as long as they're supposed to.
I just put one in the bedroom. The fixture is over the bed and I'm uneasy about climbing on the bed to replace bulbs now that I'm 72. Everything I've read indicates this should last a long time and be a cost saver in the long run. Hopefully, no more climbing on the bed.
The unit I purchased emits an audible noise - not useable in a table lamp or similar application where people would be near by. Very annoying.Also, the unit has a "CE" product safety certification, which is applicable in the European Union. The unit I got does not have a UL label or marking, which is the product safety agency listing applicable in the US.
Nice bulb. Replaced a 60w incandescent flood in a recessed can in my bathroom and this bulb is brighter. Really lights up the bathroom.I bought the warm white 3000k bulb. It's a little whiter than the old bulb, but not glaring. I like it.
