I used these in my street lamps, we have no street lighting on our residential street. My apartment requires quite a bright light to make it seem not dark, and we were using a regular 300 w bulb that would burn out in just a couple months.
Excellent replacement for 3-way incandescent bulbs. The bulb fit right into my bedside 3- way lamp.
Buyer beware this is an inferior product. There seems to be a defective bath judging by the other comments about super early failures.
The bulb gets hot and the solder on the circuit bords start to crack or melt.
I was impressed with the brightness of the light but disappointed with the life of this bulb. Seemed very bright when first installed but after a day or two seemed to be pretty dim.
We are delighted with the difference these bulbs made in our livingroom. They provide light bands that are comfortable to me. They are new and in an infrequently used bedroom.
These are oversized, do not fit in older fixtures and are apparently too dangerous to be returned. The base of the replacements are too small and won’t screw in.
Leds are theoretically greener and use less electricity to function. The only one that lights up is the 50 watt. They were likely written in review writing boiler rooms in china or the philippines.
With sporadic use, the 3 way ability was lost after 9 months time. Amazon shows a 2 year warranty, but there's no way to reach the seller. I rec'd bulbs 1/31 and the bulb blew out on 2/1.
