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!

Super bright! Super cool!
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

Very bright light.
This is a great light for brightening up an area. I wanted to use it inside of a softbox but it seemed to have a little bit of a hotspot. There are ones on here that are made for this specific purpose and I ended up going with one of those instead. They were just softer overall and I didn't see any hot spots. This is a great light though if you're not looking to use it for photography.

Lit up a large room that was too dark
So far these have been a good investment as they provide a lot of light but only use 40W of electricity. Make sure if you are putting them in the power is off to the light or make sure not to be looking at the bulb as it is very bright.

Clear lightning
The lighting is awesome. It covers a large area. The problem I have I searched for outdoor lightning and this bulb is thr first one on Amazon that popped up. My bad, I didn't read all of the discriptions which states indoor bulb. The saving grace, it can be used outside in a coach light, which is what I need it for, outside coach light. I only turn it on when I take my dog outside. We don't have any lions or Tiger's, but YES, bears, skunks, wolf's, foxes and cougars around. Hopefully this bulb lasts a long time because of the price, expensive.
