What did you mod today?

Thanks gchart! I really like 4500K, but I think I still prefer 4000K overall.

How hard was it? I have a Skilhunt H03 FC that I really like, with neutral white, but would like it to be warmer. I have some Nichia 219B coming.

Since I couldn’t pull the tube and driver (mine’s epoxied?) I had quite a dificult time manuvering the noctigon mcpcb in through the bezel. With the short, unruly, wires tucked one way or another the mcpcb’s reliefs were barely enough to rotate it in. I had planned on needing to remove some material from the mcpcb but that wasn’t required :+1: It is possible though tight to fit and I had no issues with centering after ensuring my mcpcb was properly seated.

only thing I would do different next time would be to use a proper torx driver

Made a D80V2-SBT-90.2 today.

I had a 5700K Luminus SBT-90.2 from Neal that I did an output test on and it needed a host. Of course a big head thrower is the obvious way to go but I have a FT03 with this same led coming in the mail (some day it arrives) so that is already taken care of. So I went with the best 18650 host on the market (thanks to TheOnlyDocc :+1: who worked together with LuckySun, Lexel and BLF to make this finetuned version), the Wildtrail D80-V2. DBCustom beat me putting this led in a small host (he used a X6), but I think it is more than worth the trouble.

The challenge was to fit the led in the reflector that was never made for this fat led, and get it focused. I hoped that when the reflector hole was reamed so that it fitted flush around the black frame on the led that holds the glass window, so sitting on the led base, that the focus was ok too. And luckily that was quite right. With that hole size a thin edge of the reflector base remained and that was all that was needed to make it work. I slightly sanded that edge and then put a layer of Kapton tape on the edge, and also a layer of Kapton tape around the black frame on the led. This was needed because there are a couple of conducting dots in the corners on the led.

After this, this mod only needed two spring bypasses (18AWG at the tail, 20AWG at the driver) and the light was good to go. The stock 20mm Lexel driver is a fine FET+5+1 type, and the stock switch is a nice fat Omten one.


It took me 2 hours to do this mod (but the led was already reflowed). I’m not good with dust as you can see in the pics, dust does not affect performance but I should do a better job cleaning the reflector from the metal shavings that were formed when reaming the hole.


The performance is just great. With a fresh VTC6 and a clamp meter on the tail I measured 19 A. The output at startup is 4300 lumen (corrected to maukka calibration), at 30 seconds the output is 3950 lumen (just 8% drop) and the throw 118 kcd. After 2 minutes the head becomes really hot and a stepdown is desired.
It is refreshing to have a compact light with so much output that is not a flooder but a potent thrower :slight_smile: . Only the SBT-90.2 could make this possible

Nicely done djozz! :wink:

Gotta love the little big lights! :smiley:

Outstanding and budget-friendly! Sort of ...

The Wildtrail D80-V2 has a flintrock-bistro driver that can be set to precisely the 6x7135 engaged. I did some measurements on the SBT-90.2 mod: 2.16A, 808 lumen. The led at 2.16A measures 2.76V. So when the battery at a current of 2.16A delivers 2.76V (ignoring resistances in the flashlight, at 2.16A the voltage drop will be very low) the flashlight efficiency is 136 lm/W. Really high. Unfortunately in the entire range from full to completely empty, a VTC6 at 2.16A has more voltage than that. i.e when full it runs at 4V, the efficiency is thus 94 lm/W, which is still pretty good. So at low currents the SBT-90 has good efficiency.

Host: 27
Led: 35
Board: 2

64 dollar , hmm, how budget is that? :person_facepalming:

This is really cool! What gauge wires are you using between the driver and the MCPCB?

I left the driver in place, these are the stock wires, I think 20 AWG. If the current had been low-ish that was a next job, but 19A on a full battery (prob. slightly lower with tail in place) was fine.

I’d say moderate budget. :wink:

Like i said, sort of.

SBT, we all know it’s pricey but the host is where you can save money.

Not like faulty FT-02 2020 edition with failed driver, 44$ went to drain...

I put a MTN-BST3 Boost Driver and a XHP35 HI C4 40E 4000K CRI80+ emitter in a Convoy M21C.

Distance to the windmill just shy of 700 meters. Click beamshot image to embiggen

Looks very good khas! Did you get a good tint? And what is the current from the battery?

I recently got the L21A with XHP35, which is single cell as well.
On turbo i measured more than 9 Amps! according Convoy.AE it should do 2,3A to the LED
So it roughly makes an efficiency of around 75%

I bought some boost drivers from Convoy that are perhaps the same ones that are in your L21A, I used them for a GT40 led (also 12V) but at highest setting I get a pretty annoying whine. Does your L21A have a whine also?

I got lucky in the Kaidomain tint lottery this time. I have no way of measuring the CRI but I think is higher than 70.

It draws 9.68A on a Vapcell INR21700 fresh from the charger, not as impressive as your D80V2-SBT-90.2 :+1:

2 days ago I modded 2 lights and made my current EDC set!
On the Panda White Tool AA V2.0 I put a: pebbled optic, a Luxeon V2 3000K from led4power, a 15mm driver with Bistro HD OTSM from Lexel , a rubber tailcap from On The Road i3 , and a blue acqua GITD tube from CRX. The dangler and the skull are from AliExpress stores. The lighted switch was put on this light by Henk4U2 from whom I won the light :blush:

On the Convoy S2+ mini, I put: a lighted tailswitch from Convoy, a blue ruber tailcap from Kaidomain (AliExpress store), a pocket clip from the Nitefox ES10K (that I modded with butane lighter to modify the colour), a 17mm driver with Bistro HD OTSM from Lexel that I bought a while ago and that I had in use in another flashlight,, a Carclo 10511 from Nealsgadgets, a triple board with 3 XP-G2 S4-5A from Jaxman, and a blue acqua GITD gasket from CRX! The pill + spacer (from kiriba-ru) were already soldered before as seen on the indicated link!

The Black Tool AA V2.0 mod has been documented before.

All the lights have the same UI configured: Mode 9 of Bistro HD OTSM [ ONE7135, 0, //9: Basic Non-PWM ~150 lumen low regulated mode] + Moonlight + access to hidden Turbo and blinkies !

Finally I am having EDC flashlights as I want and need them! :partying_face: :nerd_face: :beer:

nice 5000k, 4000k, 3000k lineup

respect and congrats on your builds, including drivers and pebbled tir options

Thanks my friend :wink:
BTW, even not being 90CRI, the Luxeon V2 3000K produces a beautiful beam and has an amazing tint :wink: In photo it cannot be shown perfectly! This is an LED you’d probably appreciate too :wink:
