Updated my EDC scratch built DBC-04 Ti/Cu 18500 light with XP-L2 V6 1C’s replacing the Nichia 219C’s and a Carclo quad optic replacing the Khatod. The optic swap required a 3.55mm spacer which I cut from brass. (had some of the hard to cut pure oxygen free copper, didn’t feel like fighting it)
I also fitted it with a double sided AR coated thick glass lens to protect the Carclo from scratches.
It went from 3400 lumens to 4123 lumens, I lost the tighter beam profile of the Khatod and now it’s a flood monster.
The triple channel TA driver keeps current draw very reasonable right up to Turbo, where it jumps from 2.43A to 14.11! The first 5 levels are all under 1A draw, so run time in everything but the Turbo level is surprisingly good. The 1000mAh 18500 is the limitation, had I made it for the 18650 output would be simply ridiculous.
Thanks MRsDNF.
Thought about rolling the head to try and shrink but wasn’t positive it would get smaller. So I went bigger on the other end. Took some time to scrounge just the right tool to git’er done. Worked and no cracks.
I found a package in my mailbox when I got home from work today. It was from Richard @mtnelectronics, which is always a good thing. Soldered up the clear C8 host with the SST40 on 20mm noctigon mcpcb with a dab of arctic silver. Mtn17dd driver with Crescendo (Thanks for that TK it’s excellent). Both springs are wire bypassed as I assume by now is some kind of BLF law. Haha.
The reflector centering disk that came with this clear C8 did not work with the SST40. I left it out and everything worked great. The last C8 I built was a XHP50.2 from a prebuilt light. That light had a square hole in the disk that sat around the emitter base which worked perfectly.
The same XM footprint square hole centering ring will work with your SST-40, but the trick is finding one that also mates up with the opening in the C8 reflector. If the hole in the reflector is too small you can open it up to match the centering ring by using one blade of a good pair of scissors, carefully and from the outside (bottom) of course, taking it slow will net you a nice fit if you are into that kind of thing.
Thanks for the input guys. I’m actually happy with how this one turned out without the ring. I guess I got away with one this time… I’ll have to grab a couple to have on hand for the next one.
So the round hole centering ring that came with the light I assume is for XP size emitters?
Probably, yes. Simon made a new ramped or bevel style centering ring for the XP-L and it works very good, but it doesn’t help much for those that use XM-L2 emitters or other’s in the same footprint.
I loved my quad m2, the only problem i had with it being that with the way the o-ring sits on the optics liner it was not waterproof, as water could get in the light by going around the brass liner (see image below for a poorly drawn example).
So I sanded the sides of the liner so that the oring would be pushed towards the body forming a complete seal, and swapped the oring for a thicker, GITD one.
After some testing it seems to be completely waterproof now, and the GITD oring looks rather nice, so I’m pretty happy with the results .
Actually, Im not sure that you can use any inner bezel type light with one o-ring under glass and be sure in waterproofness (only exception is P60 with L-shaped sealing). When it is possible, it is better to add one more o-ring between bezel and glass.
P.S. Inner bezel is fail, I can understand why it is so often used. Outer type (like X6, C8, M43 etc) is ways better solution.
I love my M2, but I want to replace the glass lens but the stock one has an odd thickness to it so most replacement glass won’t let the bezel to screw down all the way. I also have a quad setup for mine.
Finally printed out the BLF Q8 diffuser. The first try the side text was too thin so it had holes in the letters so then I changed to use protruding letters on side instead of sinked.
Work in progress
On the light:
Powered on:
The Q8 is on 1500 lumens ramping level without diffuser andthat is what I saw with naked eye with diffuser on:
Updated the UltraFire UF-10 with a Nichia 319ATE SM655 D440 6500K emitter for a nice hexagonal spot.
MTN FET driver, 16mm Noctigon, reverse clicky, 16500 cell.
I had originally modded this light with an XP-L HI but always wanted to try the Nichia under a plano aspheric, I like it better now :+1:
Although the camera doesn’t pick it up quite right the centre picture gives a rough idea of spot pattern.
It doesn’t quite reach the sky and has lost some throw with the new emitter but is still not bad for a compact wee pocket rocket
XP-L HI Version rough numbers:
4.5A Max
Flood - 1120lm
Zoom - 406lm
Lux – 29000
Throw – 340m
Trit tube looks great CRX. Nicely done, spacing looks perfect. Really like the inlay glow spinner too. Hope he has it for the 20+yr trit life.
I was messing with a Convoy BD06 today. added a couple 380mA 7135, bypassed the springs and swapped emitter from 1A tint to a 20mm Noctigon XM-L2 T6 4C.
The T6 came in a Red s2+ I grabbed at a cheaper than host price. Kinda just bought it for the emitter and maybe another project someday.
BD06 is a nice 26650 light and has the 12 mode Biscotti. Has rings in wall shot but not bad for something to use out side. Measures 3.65A at the tail on my DMM and 4.15V KeepPower black. Not sure why its slightly higher than the total of the 7135’s but I’ll take it.
