Sometimes I find myself, with a mini mag host…

I’ve tried some reflectors, and at least two TIRs,
some 3mil. some 5mil. XPL2,
some beers,
well today it’s aspheric, lens scratched up the most,
it’s not bright, wont reach far,
but still I must post….


3000k 5mm LED ground and polished plus some silver marker sloppily applied to kill an artifact


Head [dis]assembly.
Took me a while to realize how to make it turn on and off the original way, but it does.

Big Smile retro?

Cool. Smile
A narrow-beam 5mm variant could be quite efficient in this setup. Smile

22mm should do it.

Agro, true direct drive Wink any inefficiencies are to blame on the LED, abused optic, or host itself. Thumbs Up

id30209, with regular batteries or NiMh it’s pretty much a moonlight mode that lasts a very long time.

I’m feeding this one one LiFePo4 cell with a dummy cell, Party 3.2v 400mah but starting with 40ma draw it lasts long enough for me. Thumbs Up

I meant that typically aspheric lights are very inefficient when focused. Optically inefficient.
But 5mm LEDs come in narrow emission variants that could avoid most of the light losses. And despite the fact that the LEDs themselves don’t tend to be efficiency leaders, the whole setup could be fine.

I planned on doing a simple mod of switching out the butterfly XML reflector gasket on my clear S2+ to an XP gasket. The LED was perfectly centered, but I didn’t like how it looked.

When I took it apart, there appeared to be a gap between the LED MCPCB and the pill. When I removed the LED, the thermal compound barely spread. The wire holes in the pill were not chamfered enough to allow the MCPCB to lay flat so I sanded them down.

Everything looked good, but the Samsung LH351D 4000K 90+ CRI beam was still poor (though better than with the original smooth reflector). There were a lot of artifacts and I thought about installing a frosted lens. Then I noticed the reflector looked pretty smooth at the base given that it was OP. I had another spare reflector from a triple build and there was a significant difference between them in regards to OP and how the base spans out (left is the old, right is the new).

The new reflector made a huge improvement! My mod started out as simple, but after several hours I ended up with a much better flashlight.

I’d rather use my flashlight around the house than turn on the lights.

Thanks! I have a few idea just need to practice because I haven’t used a lathe in 7 years.
There she is:

It can grab a Convoy L6 so size is limited but so many good lights under that size.

Not much of a mod, but really tested my patience! I stacked a second current sense resistor on my S12 driver. Could not find the right physical size so had to go one bigger. The first attempt resulted in assembly and current check, still at 6 amps. Sad Took it all apart and worked on the stack a little more and now I get 9.1 amps!!! Smile The Nichia 219C’s at 4000k now look much better and it really does not generate that much more heat.

I really like this light, could almost bring myself to test EDC it.

It really is super compact and not quite as floody as one would expect. I really do like it, just would like ramping firmware. Does not need a side e-switch, IMHO.

Some remarks:

*the screws but also the threads in this light are made of cheese, use a very well fitting screwdriver (I had to drill one screw out, so now the head hangs on 3 screws instead of 4, which is no problem at all btw)

*there are no o-rings anywhere, just some grease in the fittings.

*the 3000K SST-20 works very nice in this light, but I regret the White Flat, it does not throw all that better than main led (it is in place of the UV led so it may get less current) and the beam is ringy.

*the ledboard fits over the edge of the driver board, but is also fixed in place with two pins that are soldered inside two small holes in the ledboard.

*it is a bit tiny in there Shocked , at these times I admire tterev’s mods even more.

I haven’t decided what LEDs I want to put in mine. Of course, mine only shipped today from China, so I have a month to decide Smile

Must have forgotten to hit post earlier…

Made a base for my LT1. Used a salvaged T&B brass floor box cover. The casting is not great and it has stress marks in the brass, so likely will not get a high polish. I need to make the black spacer ring again, not round… could not find my dividers. But, I like it. It will not tip now and looks nice on the headboard.

Put a SBT90.2 in a convoy L2. Man, it is a big beautiful emitter.

I changed the FET to a sir800dp. With an aspire 26650 and clamp meter I measured about 22A. With a 10mOhm shunt to simulate the resistance of the tailswitch I measured 20-21A. With the light assembled I measured 280kcd at about 5s after turn on. The beam looks just a tiny bit smaller than an EE X6 with dedomed SST40.

This host has seen several emitter combinations. Before this I had a spacer and 3 EE X6 reflectors. With 3 2mm WFs it pulled about 19A and did 290kcd. With my ceiling bounce calibration it did 3600 lumens. The 3× 2mm WF is a pretty potent setup. Before that I had 3 sliced SST40s that pulled 18A and did 215kcd and 4500 lumens. Now with the SBT90.2 it does 280kcd and 4050 lumens. Take these lumen measurements with a grain of salt but they should be consistent for these lights.

Serious mod! I haven’t paid much attention to those emitters, they have a hefty price tag. It came pre-mounted on a 20mm MCPCB?

Cool good too see the Lux and Output numbers… the L2 has a smaller reflector than the FT03 so I’m not that low on my Lux numbers… try a 30T in it if you have one, should boost it a bit.

. Here are the 3 FT03 I have… L/R FT03/SBT-90.2…. FT03clean de-domed SST-40…. FT03/NW (dome on) SST-40 ………all 3 set to about 80-85lms.

. Just to compare the size of the spot in the same light with these different emitters…

Yeah it’s a serious emitter. Hopefully it will become easier to get, if not cheaper. I think with all of the mods on here the emitters came from lantend in China. They came bare. The footprint is close enough to the MTG that those MCPCBs work.

I was hoping for a little bit more but I’m not disappointed. You saw 22.5A with the 30T? Apparently the K75 driver pushes 28A. Not sure how we can boost the current with direct drive mods; a few VTC5A in parallel? I was thinking a amutorch AM30 with its 3× 18650 in parallel would be a good host for this LED.
