Question: How tall is bulb?
Document: I haven't had this bulb long, but for the price, I am very pleased. I will update my rating as time goes on should anything change. But for now, I don't see why this isn't a 5 star purchase.
The bulb has an natural warm glow similar to an incandescent bulb. The size is comparable to an incandescent bulb. There is no warm up like a CFL bulb.The bulb has a slight delay of about one second when you turn it on. I was not expecting this with an LED bulb. Which is a little bothersome until you get used to it.Overall a decent bulb. As the price comes down overtime LED bulbs will be another energy efficient alternative to the incandescent bulb.
Works very well, is like a sunlight, always I use it at night in the hall to go to the bathroom
I will be seeking to return these if I can find the boxes.
I was looking for an energy saver lamp. LEDs seem to save energy and have no mercury.This lamp has a very natural light distribution due to its uniform light emission of 260.Color rendering is also very high at 2700 Kelvin
I really like the color of these bulbs they are very bright but warm. To early to tell if they make a difference on my electric bill.
I purchased 5 of these to replace my outside lightbulbs that were CFLs. I was pleasantly surprised to find that bugs are not attracted to the light from these LED bulbs. I went from having the flying mass of bugs in my face to bright light and no bug debris. I am counting on these bulbs lasting a good long time. These 800 lumen LED bulbs are brighter than the 900 lumen CFL bulbs they replaced.
I got four of these bulbs and they replicate light just like soft white incandescent bulbs. I will purchase many more to replace the rest of my bulbs in my house. They are for INDOOR USE ONLY. Also they take a fraction of a second to turn on after the switch is thrown but are at full brightness immediately unlike compact fluorescent. Great buy at $9.
I ORDER THIS ITEM EVEN THOUGHT I BOUGHT BEFORE FROM HOME DEPOT SIMILAR BULBS.I WAS IMPRESSED BY THE QUALITY AND THE AMOUNT OF LIGHT THIS PRODUCT GIVES.I WILL RECOMENDED TO EVERYBODY.THANKS AGAIN!!! !
Great color... very easy on my eyes. I doubt anyone would suspect they weren't incandescents unless I said something. Good power consumption. I didn't expect the short delay between the flick of the switch and the lights coming on, but it's not objectionable, and (so far anyway) the lights come on at full brightness. That's a big plus.
Answer: no
