Hi, Yesterday I made this thrower, and first of all I must say THANKS to Match for the “XML direct to copper” investigation

The_ PILL
With the led soldered on it (I used a little bit of FUJIK with the emitter’s -, I tried without it at first but it was in short, so reflowed again.
Size comparison with the SRKING
Second emmiter installed…
SRKING on the LEFT (i can’t see it, but it was turned on pointing to the wall)
Same here, SRKING on the left:
I used an XM-L U2 1A for this. The first LED I installed was perfectly soldered in the pill, but afters hours of trying I couln’t stick the positive wire into the LED’s , because the copper didn’t heat enough… after too many tries, I dedomed it and then it was destroyed… so I started all over again, but FIRST I put some solder wire in the with the led on it’s original star, and then reflowed it in the copper. The second reflow wasn’t so good as the first one, it is a bit off-centered… but it was the best I could, I should fix it to get a perfect square.
No driver used, direct drive is the way to go in this case. No magnets used either to enlarge the battery.
I don’t have a luxmeter yet, one is on the way (may be two more weeks). I want to post lux readings and then de-dome the LED to compare LUX readings.
What do you thing of dedoming the led in this case, is it a good idea or bad? I just want a super thrower with XM-L, so it’s better if the beam is too tight and narrow.
Thanks for watching
