1. Did you use the heat transfer gum paste between the board?
2. I think it has an auto shutdown feature when it gets too hot. If that was active, it would be impossible to fry if use within power supply spec.
3. High batts drain. Charge your batts again. It could be protection circuit inside a batt shutdown.
Wow, crap! Maybe those KK's were too much. Let me know if you want me to take a look at it because I got a spare driver, or I could even swap in the original driver to get it working. Hhhmmm... I think other guys were having issues with these IOS and KD drivers - can't recall details...
I get 3A tailcap with 4 battery, not impressive.
Then i got an extra extension tube and change the driver.
Result: 5x Sanyo 2600mah get 7A tailcap current! Impressive amount of light!
Waiting for my last Sony 26650 50A battery and will see if the light handle 5 of them!
Try to get beamshot to you guys but i dont figure out to do it.
you can get to the driver? oh cool… and yes please post the the mod to this light.
I have one too it’s bright but could be better…hmm i didn’t know you can add another battery to it and still work
BTW… which driver are you planning to swap it with?
The Reading I posted was With the driver installed and 5x battery.
It is a driver for SST 50. I also use this driver to my 12X t6 lights. Have try to install 4 of the KD 9A driver but all this driver died or dont work.
The Board is big so you has to remove the treads to get it installed.
It is the batterytube who fastend the driver. Use it with thermal paste and not use any spring. The driver is designed for up to 18volt input. The tailcap is about 4A with 4x battery and 7A with 5x Sanyo 2600mah.
Here is link to the driver. This guy deliver now tiny driver Board for SST led.
