It's a light bulb. It works. That's it. The problem: It's not bright enough and the light it does emit is too blue/not white enough.

Replaced old bulbs which were halogen that produced alllot of heat in studio this summer. Great light, extremely pleased.

These lights are easy to install. They are not as bright as the Quartz but not as hot or power hungry, either. Ihope that they last a lot longer.

I think it isn't possible to pack enough LED into a bulb to equal the brightness of the halogen this replaced. I would say about half the light. But pleasing color temperature, and far less heat in a studio setting for videography.

Took about 10 minutes to install . Doesn’t generate heat like halogen bulbs, excellent brightness . As far as longevity only time will tell

I own nine 100 and 150 watt quartz halogen wall sconces used in the bathrooms, hallway and bedrooms. Replacing those hot, energy-sucking and hazardous halogen bulbs with LED bulbs was a revelation. The warm white LEDs closely match the light output of a regular 100 watt halogen bulb. I liked these LED's so much that I retrofitted my larger 150 watt wall sconces to take the smaller 118mm R7S LED's.These 10 watt LED bulbs save on electricity, of course, but they are also safer. Halogen bulbs get…

These do not exactly fit a work lamp that takes a T-3 Type J Halogen lamp. The LED section is too long and large and the connection ends too short to fit appropriately. I had to carefully chip away a small amount of the ceramic housing to get one in the light. Pay close attention to all dimensions on your light and the LED replacement before buying.

So I wanted to replace the 150W Halogen lamp in the lamp in my wife's office room with an energy efficient bulb. This thing was about like a 75W INCANDESCENT bulb to our senses. My wife tried it for a week, but it just was not bright enough. She had me put the old energy sucking, heat generating halogen back in. I really had high hopes for this bulb but was disappointed.

This LED is a great solution to halogen but the bulb does not last long enough to be a good value. This bulb was placed in a sheltered enclosure outdoors and permanently began losing brightness- with flickering, when the weather became colder (about 5 months after installation).Update 20210401: I ordered a similar bulb, but noticed my old review for the old model now shows under the newer product. So my original review may not be applicable to new model. The old model had LEDs around entire…

I put one of these in a torchiere that previously had a quartz bulb. It was nearly an exact fit, so replacement took very little time.It's not as bright as the quartz bulb, but the savings on electricity make it a worthwhile change.

Installation was just a week ago, so I have no idea what the bulb life will be.The bulb is not dimmable with the usual electronic dimmer - it just flickers and extinguishes.Brightness and color temperature are comparable to a 60 watt frosted incandescent bulb.

Simply replaced the bulb in my old energy draining, heat generating halogen portable work lamp with this LED bulb. Fits and functions well. Just need to see how long it lasts. Haven't used it yet for any extended period, only tested it. So far, so good.
