Chinese lumen claims are usually way off. In most cases the claims are unrealistic high. In some cases 2-3 times higher than claimed or printed on the lights…
It all depends on how well the light is driven (how much amps the led are getting.)
Scaru have written some articles. Check this out: Cree, Luminus, Seoul Semiconductor, and Nichia LED comparison
In short: XM-L LEDS are usually up to 1000 lumen if driven quite hard in high mode (3 amps).
No homedepot here…
It is also more expensive, too big, and have some plastic parts… I would prefer one of the lights in my first posts…
Fixed title. Sorry about the mix-up…
Moved the thread to a more suitable sub-forum too.
