Well I went and put an XP-G2 de-domed in my TK61 it was a beast to get to focus correctly but I managed to get it right. To get the focus correct I removed the bottom of the reflector. Added another sinkpad under the one the emitter is mounted on and then also lifted the reflector up just a little bit. I know it sounds kinda convoluted but it's the only way I could get it to focus correctly. Of course I had previously done the resistor mods as well so the XP-G2 is pushed very hard. It's exactly 900 Lumens OTF according to my meter. I'm hitting about 700kcd on my meter give or take.
Wow, great job 18650. Would you say the beam is quite usable or not? I’ve got a de-domed XM-L2 TN31 and for me that’s bordering on being too small of a hotspot.
Thanks guys and yes it’s a pencil beam. For me it’s usable because I have a lot of open fields where I live and I love to go walking and scout deer. It’s nice to be able to check them out from across a 100 acre field. It still has a quite a bit of flood but it’s kind of ridiculous having a nice flood and this tiny bright hot spot in the middle of it. Even on low the hotspot is very bright. I would say that for general use it’s still better to go with the XM-L2. But for me I have a use for the range and well I just had to see what it would do.
I was actually pretty worried that I wasn’t going to be able to get it to focus. I think I spent a good 6 hours or so messing with it before I got it right. But once it finally fell in place it was a perfect hotspot.
Thanks and yep getting the focus correct on these takes some doing. Especially on the bigger reflectors. It literally has to be perfect, the tiniest bit too high or too low or side to side and it’s a mess.
It’s under 6 amps so I suppose there is room for more amps yet. But then you really hit the point of diminishing returns.
