Very bright
Very bright and easy to install. The warm white color is perfect for my outdoor light, and it provides excellent coverage. Great value for the price!

Super Bright Bulbs
I’m really pleased with how bright these bulbs are. They put out a strong, warm white light (3000K) that feels comfortable on the eyes but still makes the space look clear and well lit. The 300W equivalent brightness in a compact “corn” style bulb works well for places that need a lot of light, and the E26/E27 base makes them easy to swap into existing fixtures. Highly recommended!!

Not as bright as advertiswd
Bulb is not as bright as advertised. It replaced a 70 watt HPS after converting to LED. Light output is definitely much lower. Does not even come close to illuminating the area that the HPS covered. Reminds me of a 100 watt incandescent bulb. I concur with the other reviewers rating this a 1. I may not be an electrician but I can tell a rip-off. These are off brand and not as represented. Of course, made in China.

Fits and it's bright
Nice bulbs, perfect for bedroom light or similar where you need light without one bright spot what emits it. Soft color yet bright, good for reading.. will work for dining room as well, I will consider that idea but bedroom so far lol good size fits the socket but the big is raised so consider that. Didn't see flickering

Sorry, but less than half the rated power and lumens.
First off, I do like the warm color of these bulbs, but have tried several types from several sellers and have always been disappointed, and these are no exception. They're listed as being rated 40W real power draw and 5000 lumens total light output. Sorry to say, these bulbs don't even meet the halfway point. In my side-by-side tests, they're a bit brighter than 100W hotwire bulbs, but nowhere near "300W equivalent". In fact, they only draw 19W, and according to my indirect brightness tests (via "ceiling bounce" and light-level metering) they only get to somewhere between 2000lm and 2500lm, again, nowhere near the claimed 5000lm. I tried contacting the seller directly to ask for clarification, but have not received any response as yet, so I can edit the review to clarify if/when I hear back from them. Markings on both the boxes and on the bulbs themselves say "40W", so I don't know if I got mislabeled bulbs by accident, if they'd send me correct bulbs in exchange, or what. We'll have to see. All I want is to be able to get high-output bulbs, which are always priced at an extreme premium, and just get what I paid for. I don't think that's too much to ask. Worse comes to worse, I'll just return the bulbs and get a refund, but I shouldn't have to go through that in the first place if the products being sold would simply meet the advertised specifications. Imagine ordering a yardstick for measuring things, and what you get is only 15" long instead of 36". Or a 25ft extension cord that's only 10ft long. C'mon!

The brightest bulbs I could find in this size
I have sconce lights that are too narrow for normal-shaped bulbs and will only take "skinny" bulbs like these. Are these bulbs actually 40W and 5000 lumens? Probably not, but they're definitely at least 2-3x as bright as the 9W/800lm LED bulbs they replaced, and are the brightest bulbs I could find that come in this form factor.

Far from the advertised lumen output, weak bulb
Low light output, far from 5000lm, not worth what they are asking.
