R7s LED 118mm, 110V J Type Double Ended J118 LED Bulbs, 30W (200-250W Halogen Bulb Replacement), Dimmable 2700 Lumen Daylight 6000K Floodlight

I bought these two years ago. One died after 2 years use of about 2-3 hours per day (maximum). There is only a 90 day warranty .. .so...... I bought these to replace them.Both are 118mm halogen replacements. The COB bulbs are higher wattage but less bright, I think less lumens. Theses are 6000k truly and the COBs are 5000k or less. The Attaljus are whiter, clearly. The COBs are more shaped like traditional halogen bulbs whereas these Attaljus are larger in diameter (3x or so), but have the insert plugs on the outside of the cylinder radius thus leaving typical clearance from pin to surface but occupying a full 1" of space down compared to 1/4" of a traditional halogen. The Attaljus pair of bulbs are a few dollars more. Last these bulbs use a dozens of tiny LEDs instead of a COB elementSummary: The COB bulbs are a bit dimmer (both are dimmable), smaller (traditional size) and a touch of yellow (not anything near a "soft white" yellow, but noticeable when compared to these Attaljus or any other 6000k bulb. Although these Attaljus are rated at 30000 hours, one of mine died as noted above. I replaced the still working Attaljus bulb with the second in the COB new pair so the two matched in the fixture. They work well (2 days) and the color difference is not apparent with the rest of the other 4000k-5000k bulbs in the room. Both are good for the price with the exception of the failure of one of the Attaljus after a max of 3000 hours of use.

This fits a 20 year old dimmable 300 watt torchiere easily. Very bright. Nice soft color. No noticeable buzzing sound. The dimmer woks, but if you leave it below the half point or so, it will not light up on its own when switched on with a timer or a wall switch. You will need to turn it up a bit and turn it lower after it comes on.

Had this torch light for years and always worried it might fall and start a fire with the 300W halogen bulb. Now that it has an LED with 150W equivalent bulb, its not the ceiling super nova it once was. But it does do a good job of lighting up the room, without the threat of lighting the room on fire.Cheap insurance and allows me to use that which I already have...

These bulbs are working so far, but time will tell. The last set of bulbs I purchased dimmed to a useless level of light after a couple of months. For now, I give them a good rating.

Despite getting the wrong size sent to me originally (78mm rather than 118mm), I am very happy with this purchase. The size and shape of this bulb is perfect for my ceiling fan and both bulbs worked perfectly (tested the spare). I use a dimmer so the normal setting of my old halogen was about half power and, even if this claims to be a lower brightness than that 150W bulb, the dimmer has to be set even lower to give me about the same illumination in the room. At full, it is more than bright enough for my needs. I hope it lasts at least as long as the halogen which was originally installed 12 years ago and was still going strong.The only less than ideal aspect of this bulb is the fact that, with my Lutron Maestro CL Fan/Dimmer combination switch, the bulb glows a little when the fan is turned on without the light switched on. Lutron says that this has to do with how some bulbs aren't as compatible as others but, considering how few similar bulbs are available (none locally), I'd rather live with the glow than go through a trial and error process. If the bulb ever needs to be replaced, I'll consider trying a different manufacturer but, assuming that's a long time from now, I may just want to stick with a winner. If it becomes an issue or the bulb doesn't last as long as I expect, I'll update this review.*update*Couldn't stand the glow on nights when it was hot inside but too cool outside to use AC. Switched back to halogen bulb (don't turn light on much and rest of house is LED) and will eventually replace the fan with something that uses regular LED bulbs. These are still great for any lamp that doesn't suffer my fan/Lutron dimmer problem.

I don't know how many of these light I replaced, but still working longer and cooler than the filament style.

This LED bulb isn’t an exact replacement match for the Halogen 300W bulb I purchased over 6 years ago for my torchiere floor lamp. HOWEVER, it works as an 150W replacement and that’s okay. This bulb is warm to the touch so the lamp is no longer potentially dangerous/hazardous. The light emitted is ample for my purposes and the reduction in wattage used is noteworthy (from 300W to 15)! The bulb is dimmable by the way!I highly recommend it.

Replaced a 500 watt quartz on a dimmer. Just bright enough for reading but I wish it could go brighter when needed. I'd buy it again!

If you need a 300 watts equivalent (the replace the 300w halogen bulb you wont be satisfied.In my case since the lamp became so hot I decided to replace the bulb and it does what i needed.It also work well with dimming (in my case i use Luton Caseta plug)

It’s a nice lightbulb… LED. 6000 color which is nice bright blue light. In my own opinion it’s probably as bright as 100 W bulb not a 200. It’s dimmable but it doesn’t dim as low as I would like. And you have to turn it on full blast so the LEDs light up otherwise if you start off slow there’s no light. It’s OK not worth the money though.

Pretty good brightness & dimmable. However they run hot. One of the two began to emit chlorine like smell & stopped working after about a year an a half. Would not repurchase

Used in our art room where bright lights and true colours are important. an improvement over the halogen bulb it replaced.

Good thing the order included two of them!
