Quick update,
I got it put back together and measured lux at 10 meters. I got 2190 lux. I used (3) 26650 flames I made a short filler with a piece of brass to get the contact in the battery tube. I did measure current at the emitters with the light assembled and it was 5.1A. Probably because of the extra resistance of the brass spacer. Beam shots tonight! (Still daylight here)

2.4A
5.1A
There it is. I barely got one shot in. Camera battery died. Im charging the battery in the camera. I will probably fall asleep before it charges. I been up since 4:45 this morning!

Thing looks beast! Thanks for the shots.
looks beast?
it IS beast. lol
219kcd!!
Dedome them!!
Thank guys! Im going to do some run times and heat tests today hopefully. Will update.
I have dedomed a lot of leds. Im not to crazy about tbe color afterwards. Im happy with 219kcd!
This light is sure a lot lighter now with 3 lithium batteries!
Oh yeah, strobe is wicked on this thing!!!

What is the input voltage range of a stock TK70?
Stock TK70 takes 3-4D size batteries. Alkaleaks or Nimh
Working Voltage: 4.8V - 8.0V
Max Input Current: 6.5A - 7A
From a quick google.
I think my input current was less than 3A with the 3 lithiums. I can check later to verify. Dont hold me to that number just yet.
Ken
Thanks for your link.
The Thai TK70S version uses either 2 li-ion or the usual 4 nimh
All TK70 can use 2 Li-ion cells. Not sure about 3 though.
Two of either links will be good enough?

(as long as the D cell)
Yup!
Have you tried this set-up or something similar? Aside from the weight savings, what are the other things that can be gained with such set-up?
Shorter and better balance with a dummy cell near the head. I would prefer a 2D tube but cant find one.
I just measured tailcap current with 3 fresh 26650s. It was 3.84A on high. It stayed at 3.84A for 30 seconds of run time. I suppose my driver is safe!
Ken
wow nice mod! can you tell me how many lumens now?
I can only really go by Matches test on the XML2 led on copper test. At 5100ma I would be at 4800 lumen. I like this light a lot because the reflectors are deep and it really throws well! I believe there is not a true way to convert lux to lumen?
Ken
So you have the stock driver in and running at 12.6V?
And its not smoking?
