Incredibly Bright and Energy-Efficient – Perfect for My Workshop!
I recently installed the SANSI 400W Equivalent LED Light Bulb in my workshop, and I’m absolutely amazed by its performance! The 6000 lumens of brightness are incredibly powerful, lighting up the entire room with ease. It’s like having daylight in my workshop at all times! The 5000K daylight color temperature creates a bright, crisp light that makes everything so much clearer and easier to see, whether I’m working on detailed projects or just organizing my tools. What really stands out is the energy efficiency of this bulb. Despite its high brightness, it only uses 40W, which is an impressive energy saving. With a 22-year lifetime, I won’t have to worry about replacing bulbs anytime soon, which is great for long-term savings. The E26 A21 base fit perfectly in my light fixtures, and it was super easy to install. It’s also non-dimmable, which is perfect for the kind of consistent, bright lighting I need in my workspace. I love that this bulb doesn’t just give off great light but also saves me money on energy bills. If you need a highly efficient, ultra-bright LED bulb for your home, workshop, or garage, the SANSI 400W Equivalent LED Light Bulb is the perfect choice. I’m very satisfied with it and would highly recommend it!

Look great and right in color range!
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.

LOVE this bulb. Super bright, super convenient.
I recently moved into an apartment with terrible track lighting on high ceilings. Regular efficiency bulbs were all but useless in the pots because of the high ceilings, so I replaced ONE bulb with this - and it is enough to light my entire office area with ease from a high ceiling. Looking to see if I can also replace a bulb in my kitchen ceiling fixture for better light in there.

Super Bright and Perfect for Work and Home!
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.

Excellent output. Impressed. Buy it.
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.

Not very High Efficiency
Very bright. But not high efficiency as claimed! This 200W bulb uses about 23W like others.

I feel like I am working during a bright, sunny, summer day on December 17!
Holy Cow!! This is amazing! I work from home and in the winter months, the light from my lamps are not bright enough. I have been looking for several years for a solution including buying multiple lamps without much help. I saw this on sale before Christmas and decided to take a chance and it is awesome. It is very bright and makes it light daylight (the good Summer daylight) in my office. I have only had it a few weeks so I can’t comment on duration but I have not had any issues with flickering. It fits in a regular light lamp.

Very bright light
I have low vision and need bright lighting. I had a Sansi daylight bulb with 5000 lumens in my kitchen. I exchanged it for this Sansi soft white bulb with 6000 lumens and like it much better. It provided more light and it’s not as glaring as the daylight bulb. It’s not dimmable but I didn’t need a dimmable bulb.
