10,000 lumens, if actually legit, is insanely bright. I have a DeWalt one rated at 2,000 (I trust DeWalt's rating) that is plenty bright. https://a.co/d/03W6SMhV

Edit: I just did some back of the envelope math. A very high efficiency LED is about 200lm/w. 10,000 lm divided 200 lm/w = 50 watts.

The battery is 12 Ah. 12 Ah times 3.6V (typical li-ion voltage) 43 wh.

In other words, based on the advertised specs, it will last less than an hour on a full charge. And that is being very generous with the efficiency of the LEDs.

Problem with these knockoffs you cant trust the battery. At least Dewalt battery is superior and replaceable

The battery is not very large, and ironically I trust the battery spec more than the lumens spec

Price for specs seems like a good deal. Specs vs reality - you feeling lucky?

Good deal. 10,000 lumen seems suspicious though...

It goes without saying that this exact light is sold under different brand names and by several sellers with different names. Who knows if it's really just one seller. But it's certainly the same light. One example: https://www.walmart.com/ip/176846...b41acafdbe
Just don't expect similar performance to a name brand…

Assume you're never getting anywhere near 10k. Maybe 1k-2k which still isn't bad, plus the rechargeable battery.
