SANSI 400W Equivalent 6000 Lumens Brightest LED Light Bulb 5000K Daylight E26 A21 Super Bright LED Bulb Non-Dimmable

Purchased these to upgrade the lighting in a 50-year-old house with limited overhead lights and much of the lighting via 50-year-old table lamps. 15 minutes after installing them went back and ordered more for the rest of the house! Six of these will easily light 1,000 ft² PROS This bulb runs cool enough to be used upside down in a totally enclosed light globe without creating dangerous heat. After hours of on time the globe and metal base are cool enough to be safe to the touch. The bulb runs even cooler in a traditional upright lamp application. For a bulb with this much light output the size is very good. The neck is long enough to fit into very old lamps without any clearance issues. The bulb is still short enough to fit inside of some very old ceiling fans that typically have clearance issues with brighter lights. CONS The bulb uses a hollow core design which greatly aids in keeping the bulb cool. However the open top design creates a dark circular shadow and a light output when viewed directly head on. The light output color is extremely white which may be somewhat harsh or off-putting in some areas where a more natural daylight color tone may be desired. These bulbs are super white. The lifespan of this bulb is still to be determined. Paid review: No Would purchase again: Yes Read more

The SANSI 400W Equivalent LED Bulb is unbelievably bright—at 6000 lumens, it lights up any space like daylight. I use three above my kitchen island, and it makes cooking and working in that area so much easier with the clean, crisp 5000K daylight color. I also replaced the two bulbs in my office, and the brightness keeps the whole room well-lit and comfortable for reading, writing, and computer work. Even with this incredible brightness, it only uses 40W, so it’s very energy efficient. The bulb feels sturdy, runs cool, and with a 22-year lifetime, it’s built to last. Overall, it’s the brightest and most reliable LED bulb I’ve found, and I highly recommend it for kitchens, offices, workshops, or anywhere you need excellent lighting. Read more

Bam! Bright! These things are a huge upgrade from any "normal" LED bulbs and they fit right in an A19 (standard) socket. I was afraid these might be slightly too big around to fit in the tight space I had in an overhead fan, but they fit exactly and the light output was AMAZING! No word on longevity yet, because they haven't been in long but so far these don't flicker, they don't got overly hot, and the light output color is right in range. I needed something a bit softer than daylight of 4000K, but didn't want to go all the way to 2700K and these 3000 soft warm came right in if not every so slightly above their target. Yes, these are expensive, but for a 250W equivalent in this package size, I haven't found any better. Read more

I collect high end flashlights with true lumen ratings output. I wanted a better bulb for my backyard so i can see my dogs better when they're outside. I seen this 6k lumen bulb and thought I'ma give it a try. No lie, this bulb is not a joke. I believe it's true to its lumen rating and it almost turns my back yard into daylight... almost. It even lights up the trees a good bit and my neighbors fences and houses a decent amount. (I think they're gonna hate me soon). When my girl turned it on, she called me on the phone and said the exact same thing... "I think or neighbors are gonna hate us." In the far distance, it's visually brighter for your eyes than it is in the picture i took as my camera dims the brightness. But, it'll give you a good idea. If you want an excellent bulb to really light things up this was well worth the price. Hopefully it last near 50,000 hours or so most led's are rated for. Time will tell. If i get even just a year use out of it though i will rebuy it again when it goes out. I will post a picture i took the first night. It's roughly about 150 feet from where my bulb is to the woodline at the very back of my yard and almost 200 feet to the same woodline on the far right of my yard to my neighbors fence. Read more

I bought this bulb 14 months ago and it has worked very well. It is bright with no flickering. Unfortunately, it stopped working two days ago. I contacted the company (through Amazon) and they replied within 12 hours. Their reply was “sorry you had trouble with our product, Please send us your shipping address and we will send you a replacement. “. WOW! I will certainly buy from these guys (Sansi) next time I need bulbs. Read more

Very bright. But not high efficiency as claimed! This 200W bulb uses about 23W like others. Read more

I use these in my 24" E26 softbox frames. They work well. They match each other in lumens and color temperature very well. They are a bit warmer than other daylight lamps. But since I use these lamps exclusively for portraits and table tops in the studio and they are all the same color temp I am quite pleased with them. Read more

Great light for my outdoor lamp. Read more
