KL1 with Luxeon-V

[tylerdurden]

Anyone put a five-watter in a KL1? It just barely lights up, even after I boosted the circuit to 700ma.

 

[shiftd]

i think that is because the circuit output can only go up to 5V or less, which makes the 5W underdriven, no matter what you put on it(current drive, etc)

 

[tylerdurden]

Ah, that would explain that. Durn. I was going to route around surefire and make my own KL4-SG. It would have been awesome. /ubbthreads/images/graemlins/frown.gif

sorry the dumb question, but once you cracked it open isn't it doable to change the driver to a BadBoy without too much trouble?

yup yup, you can actually change the driver to a BB, so you STILL can have the KL4-SG /ubbthreads/images/graemlins/grin.gif
just need to de-solder the 2 leads that were holding the board in place (i did not know this and was destroying the board in the process /ubbthreads/images/graemlins/frown.gif )

if you willing to sell the original board, shoot me a pm /ubbthreads/images/graemlins/smile.gif

 

[tylerdurden]

Well, I was hoping to keep the original circuit, not only to save the expense of buying a badboy, but also to preserve the buck ability for 3x123 use.

It's a compromise, but I suppose you could come close with a Lux3 because its Vf is still within range.

 

[shiftd]

yea,
boost your KL1 and feed it with Lux 3, /ubbthreads/images/graemlins/grin.gif

 

[tylerdurden]

Yeah, but EVERYBODY has a Lux-III KL1, nobody has a Lux-V KL1. /ubbthreads/images/graemlins/smile.gif

That's exactly how I got a KL4 board (from a guy who modded a KL4/downboy/lux3) and now i do have a KL4 in a KL1 host with so17 reflector.

 

[shiftd]

uh oh, some one beat you, tyler /ubbthreads/images/graemlins/icon15.gif /ubbthreads/images/graemlins/tongue.gif
I just cannot understand why one would use 5W on KL1 head? the small reflector it can fit already a justification of not use it to host 5W. IMHO, 5W should be placed in anything with reflector the size of PR or larger.

 

[tylerdurden]

The only reason I would do it is because you can't get a KL4 in SG. The SO17XA is not too bad with the Lux-V IMO.

 

[Kiessling]

dito, the so17xa makes a nice flood beam with a 5W, really usable!
