Hi guys i am wondering how a 4 dies LED can produce 900 lumens @2.8A which means 700ma to each die. Even at 1A each i wont produce 900 lumens right?
Thanks.
Thanks.
Just bought one of these:

Anyone else have experience with one of these? Being from hong kong, I have no ideal how long it will last. It gets pretty hot, but it doesn't seem to be coming form the battery.
Is heat something that is deleterious to the longevity of this?
The SSC P7 'new' C bin is 700-800 lumens at 2.8A. This is currently available.
The SSC P7 'new' D bin is 800-900 lumens at 2.8A. This is NOT currently available.
With highly textured reflectors to smooth out the artifacts caused by gaps between the dies. Add currently shipping P7 commercial torches not using the best lens and output is probably only 65-70% or 455 to 560 torch lumens. Just upgrading to an AR coated UCL lens can increase transmission 10% to 525-640 torch lumens. I do NOT expect 900 torch lumens as there are always transmission losses. OTOH a modder ran a P7 torch at 3.8A and the LED did not instaflash.
The MTE 5 mode maxed out at 2.2A so output is probably less than my 455 to 560 lumen estimate. Still very bright.
