The light is not 10,000 lumens at Best with a full charge it's about 800 to 1,000 lumens on its highest setting. False claim for the brightness on highest setting. I have bought 4 exact style of lights from another store that are rated for their highest setting as being 2,000 lumens, they are brighter than the one purchased from Walmart. I've had my other lights for 6 years now. They are still functioning just fine just that the plastic is starting to fall apart. I'm just trying to get some new lights of the same style that are brighter than my old ones. I just hate to be lied to about the output of purchased items. My job has a light tester, that's how I know that at Best this light is only 1,000 lumens. For the price for the light from Walmart, I think it's a waste of money. If it was truly 10,000 lumens it would be good, but it's not.
