Features

  • BRIGHT & EFFICIENT (NONDIMMABLE) : Compared with other LED bulbs, SANSI's highly efficient light bulbs can provide 6000 high lumens using only 40 watt of power, equivalent to 400W incandescent bulbs.
  • FLICKER-FREE: Adopting high light transmission optical lenses, up to 216 LED chips can not only provide you and your family with the light source they need daily but also provide a healthy living or work environment. No flickering, no noise
  • PATENTED CERAMIC TECHNOLOGY: SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, directly soldering the LED chip on the ceramic heat sink, effectively reducing the system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, making SANSI's bulbs perform with higher light efficiency
  • SAFE & RELIABLE: The lamp body is made of special ceramic material, and the flame retardant grade reaches grade V0; the reinforced insulation structure means no risk of electric shock, its safer; the whole shell material reaches the WF2 anti-corrosion grade, which is more reliable and wear resistance; The hollow design is good for heat dissipation
  • GUARANTEES: ETL listed, quality and safety verified, 22.5 years LED bulb lifespan. SANSI offers 5-year protection plan and replacement bulb
  • NOTICE: 1. Non-Dimmable: This bulb is non-dimmable. Do not install it on dimmable fixtures or switches, as this may cause failure, flicker, automatic shutdown or permanent damage. 2. Usage Environment: Do not use in high-humidity areas, outdoors or fully sealed waterproof fixtures, which may affect lighting and shorten service life. 3. Voltage: Ensure the usage voltage matches the bulbs rated voltage. Mismatched voltage may cause failure or severe damage.

    • Incredibly Bright and Energy-Efficient – Perfect for My Workshop!
Color: 5000k Daylight Size: 6000 Lumen 1-Pack
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! ... show more

    • My favorite work station light.
Color: 5000k Daylight Size: 6000 Lumen 1-Pack
Expensive but it’s the best I’ve found for my work area. I’ve bought SOOOO MANY lights trying to brighten a dark area. This is the first to make a difference. It’s bright. I’ve not noticed it getting overly warm after hours of use.

For forty watts it's super bright. It'll be well worth the money. If it lasts a long time, like most LED's, do

    • Poor RF filters create interference with garage door opener fobs
Color: 5000k Daylight Size: 6000 Lumen 1-Pack
I purchased this to replace the 100W incandescent bulb in my garage. While extremely bright to look at the amount of light cast into the garage is less than expected...still much better than the 100w bulb it replaced. After installing and leaving on for one day to make sure it wasn't defective I noticed the garage door wouldn't open using the two fobs and two built in vehicle transmitters unless right up against the door. Turning the bulb off eliminates the problem. A quick search points to poor RF filters on the LED emitters, creating RF interference with the door receptors. ... show more

DAMN! this thing is bright! I got it for a desk lamp hoping it didnt extend past the cover, but it did. Its a little bigger than a reg light bulb. But this bulb is bright and I LOVE IT!

    • Excellent output. Impressed. Buy it.
Color: 5000k Daylight Size: 6000 Lumen 1-Pack
Review Image by Reno
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. ... show more

    • Extraordinarily Bright

I bought this to use in my laundry room which only has a single overhead light socket and no windows. I was tired of washing my clothes and only later finding I had missed pre-treating a stain because I couldn't see it with a normal 100w bulb. This thing is amazingly bright. Like daytime outside bright. Don't look directly at it - it is that bright. It's made it a breeze to do my laundry ... show more
