Maratac aaa mod to 660nm Red
pic is a link to info about using it to stop migraines

fwiw, the mod results in all 3 modes being the same, 7 lumens on my meter. This is not a problem for use as a Red Light Therapy tool.

atm you can get a Red LED Sofirn C01R with 3 modes. I recommend them for red light therapy if you dont mod your own lights. They have 3 working modes, and are inexpensive.

I know it’s semantics but I wonder if it’s actually even going to the other modes. When I modded a thrunite aaa with the deep red I was sometimes stuck in the same mode but occasionally it would go to other modes too. Makes me think maybe a bleeder resistor or pencil mod might be able to make the mode issues more reliable. However, this is all above my electrical expertise so it’s really just a guess.

I would welcome education on how to make the modes on my AAA lights work better, when modding to Red

previously modded a drop.com aaa LMH Copper Tool,
it now has 3 modes, 5, 10, 12 lumens

this time I modded an MLH Maratac aaa to 660nm Red
it now has 3 identical modes of 7 lumens w AAA eneloop

both of those aaa lumintop drivers are giving unanticipated results.

I have also modded a Thrunite T10T to 660nm. It retained mode spacing and kept 4 distinct modes, albeit at lower level than the stock XP-L

thanks for sharing that the thrunite aaa also does not retain mode spacing, I was wondering about that, and now I dont have to do a mod myself.. I have a thrunite aaa titanium. I modded it to XP-E2 530nm Green LED, and it retained 3 distinct modes of 0.1, 8, and 65 lumens on aaa eneloop.

I dont know why green works fine to retain modes, and red does not.

on my meter the green, on second mode reads 8.4 lumens and the red reads 6.5 lumens (with the same partly depleted aaa eneloop @1.26v)

it would be great if we can learn how to make the AAA drivers give 3 modes with a Red LED..

the Sofirn C01R has 3 well spaced modes on Red.. they obviously know something I dont (yet)

The big picture explanation is this (XP-E2 datasheet):

Red and Green have very different forward voltages (in fact they are further apart than any other color)

The C01R was designed around the red’s very low voltage requirement.

How each individual driver reacts to this is what is unknown.

Also, there is an element you are mentioning “spacing” which you are using a lux meter that can barely “see” very deep red and I don’t know how well it correlates to your eyes but surely it’s good enough to know if the modes are even changing at all.

very deep red

thanks for the VF info..

fwiw, deep red, far red, photo red, are vague terms, I prefer to specify the nm

some call 660nm deep red, others call 730nm deep red. They are totally different in the amount of visible light, and that also shows up on my meter.

for example, w 660nm I get 8 lumens from my Maratac, but with 730nm I only get 0.6 lumens (which is why I removed the 730nm, since all 3 modes only give the same 0.6 lm.)

on my T10T the 730nm gives 0.05, 0.1, 1, 5 lumens
so the spacing is still there
I kept the 730nm in that light, specifically for red light therapy. I mostly use the 1 lumen level to reduce pain from arthritis, headache, sore muscles…

I dont use red for illumination.. but the 660nm does work for that, the 730nm does not..

Which model thrunite AAA was it?
I modded a thrunite Ti3 V2 with a red XP-G3 645nm and all modes worked fine.
I have the SST-20-DR-B120-V660
XP-G3 photo red 645nm
XP-E2 photo red 660nm
LH351H red 643nm
.
I still have a few Ti3 V2 to mod, which led are we seeing the mode changes disappear in.
I will see if I can duplicate the problem if I have the right red led.

I believe the problem combination (for me) was Ti3 V2 and Far Red XP-E2 but my trouble was slightly different. It would sometimes go through the modes fine but sometimes get stuck on the same mode and not increment. Like it was not recognizing it was losing power completely?

I also had trouble in a very old Olight AAA with the same LED. Memory is hazy

Far Red XP-E2
iow 730nm? Smile
I get no modes w that LED in my AAA Maratac and Tool
same issue w XP-E2 660nm

if there is a resistor mod, that would be great to learn. or
if SST-20 660nm works in an AAA Thrunite, Maratac, Tool,
without losing mode spacing, and without a resistor mod.. then I would go there

I prefer not to go below 660nm, so the XP-G3 645nm is not as interesting.. but good to know it retains modes on the Thrunite AAA.

SST-20 in 660nm that Sofirn is now using in the C01R, are available here

but the VF is similar to XP-E2 660nm and XP-G3 645nm, so there must be another factor in play for the Thrunite AAA to retain modes with the XP-G3, and not with the XP-E2

I dont see a big difference in VF, so dont know why modes are retained w XP-G3 and not w XP-E2

photo red XP-E2 VF @350mA is 2.05v

645nm XP-G3 VF @350mA is 1.99v

660nm SST-20 VF @350mA is 2.1v

well… please share if modes are retained in a Thrunite AAA with an SST-20 660nm, like they are with XP-G3 645nm

both contactcr and I confirm that modes are lost with XP-E2 660nm and 730nm, in AAA Thrunite, Maratac, Tool

I swapped the Ti3 led for the 660nm SST-20 and I get low and strobe.
I powered the driver out of the light with my power supply and SST-20 installed, at about 1.77v the modes come back and work as they should.
Not sure what’s going on with it, but I changed one capacitor value up then down with no change.
Also wired in a 50k pot for one of the resistors to get a full range of values and also got no change.
I dont know what to change yet but I know which capacitor and resisitor doesn’t effect it. Wink

thanks for modding to test
so, I wont bother buying SST-20 660nm then
and we know the XP-E2 660nm does not work either
sounds like XP-G3 645nm is the easiest way to have normal mode spacing on an aaa swap

I would prefer to try an XP-G3 660nm.. googling now

found this XP-G3 660nm

ordered a couple to test, will share what I learn

I built a Convoy S8 with quad Nichia E17A 4500K LEDs that I got from Virence. I wanted to keep the current to less than 7 amps so I got a Convoy 17mm Driver for SST40 which maxes out at 5 amps.

I encountered 3 new challenges with this build:

  • Soldering the 4 wires to the non-DTP board was very tricky! One time when I was soldering a wire, another wire unsoldered and fell off. You have to be quick, precise, and not worry about imperfections.
  • I used thinner silicone 24 AWG wire vs my normal 22 AWG, but it was still a very tight fit curling up all 4 wires into the shallow pill cavity (the S8 has the same pill as an S2). The bigger S2+ pill would’ve been much more accommodating, or next time I’ll get some 26 AWG wire.
  • Convoy states “This 12 groups sst40 driver is compatible with lighted switch.” This is true, but I noticed the output greatly decreased with a small drop in voltage when using inefficient switch LEDs (like orange). I made a salmon colored switch (pink and orange LEDs mixed), but couldn’t use it because of this issue. So instead I swapped the switch with a green one that I had in another flashlight.

And in case you didn’t know, E17As are very fragile. In another flashlight I was building, the LED spacer gently bumped against one of the E17As and broke it. Went from a nice CCT to purple. So for the S8 I decided not to use a spacer – GASP! The 4 wires on the LED board do a great job centering the reflector and the silicone sheathing prevents any shorts. Plus now the aluminum reflector helps to dissipate heat.

When I put it all together, as expected, there was a small donut hole in the beam. So I lightly frosted the inside of the lens and the beam turned out great. And the flashlight still has some good throw.

The output and tint is awesome! Certainly some nice rosiness in the tint, but a little less than my 219B sw45k S2 triple at lower currents. At higher currents the E17As are rosier. I’m not sure which I like better yet, but not a bad dilemma to have.

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

Nice. Yeah, those are fragile led’s is bumped the “wrong” way. But nice tints. I have broken E21a’s in a similar way.

great writeup
congrats on your High CRI mod

thanks for the pics.. there is one missing.. lol
(the beam)

I like my pink sw45k, but I also like the whiter whites and great color separation from the less pink tinted E21a

definitely a nice problem to have

Left pic is at low current, left beam is 219B, right is E17A. The right pic is the same, but at high current. With my iPhone, this is the best I could do to show the difference.

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

NeutralFan have you tried to use one wire with insulation cut inside? This way I was able to use 22awg wires.

Great suggestion Chatika vas Paus! I’m not sure if my soldering skills are good enough to pull that off though.

Have you had any issues using the LED spacer? I’m afraid to put one on since it would be such a tight fit and the E17As break so easily.

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