I`ve thinking of buying a 14x CREE XM-L T6 LEDs headlamp like this:
I know that 34000LM is totally bogus on these china lamps and not realistic, however since it is 14 spots, i hope that you can get som more lumen out of this by modding it.
I`ve read on the forum and elsewhere several threads about this, and I understand that each CREE XM-L T6 led has the potential of around 900 lumen max running on 1Amp, though I`m sure the led driver supplied with this light does not support 14 Amps.
Let`s say I run all leds on 900 lumen I have the potential to get 12.600 lumen from this lamp. However thinking of the heat produced and the fact that it is going to be run on batteries, running >10.000 lumen may not be possible.
In reality, how many mA and lumen can I expect to run each led light? I may have to put in a small heat sink connected to the leds.
My second question is which driver should I put in it? Something like this running up to 7Amps?
Or should I get two drivers etc. 5Amps, each driver connected to 7 leds ?
