Here's a simple and quick mod for the F-13 light.
An F13, a Qlite 3 amp driver and an XM-L2 U2 1A on a Noctigon
Started at 10:20AM
Complete tear down in about 4 minutes. I will use the stock driver as a contact plate and I will be doing the copper braid mods to the springs. I will also add 4 more chips to the driver. I expect about 4 amps.
I have added 4 chips to the driver and I have soldered 18ga wire on the star.
Arctic thermal paste, (not adhesive), is under the star. The reflector will push down on the star, when it's all together.
I used a dremel to open up the stock driver, so it's an outer ring now, for ground. I soldered it to the Qlite driver. It's not very pretty, but it is held in place and it works. I wanted to add copper under the stock shelf, but with the 18ga wires and the extra chips, there just wasn't room. The stock shelf should be fine, it's thick enough and 4 amps should be ok, with no problems.
Driver is in place.
Modified light on the Left, stock light on the right.
Same thing, but with a slower shutter speed.
I did nothing to make the spot larger. It's simply that the modified light is putting out more lumens, so the camera shows a larger spot, due to a more brilliant spot. That's my story and I'm sticking to it...
Now, it's off to pack it up and send it off.... In a day or so that is. I got to play with it tonight first.
Just about an hour and a half, to get it all put together and under a total of 2 hours, to get everything put away and beam shots done.
Oh, it measured 3.97 amps with a Sony 26650 and a 20R 18650. It really does not have the room for a protected cell, at least the modded one doesn't.
