What did you mod today?

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.

Iā€™d say moderate budget. :wink:

Like i said, sort of.

SBT, we all know itā€™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.

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 youā€™d probably appreciate too :wink:

Did you glue the clip or is it just snapped on? If you glued it what did you use?

Working on a buddies GT, converting it to the SBT-90 Gen 2. Making the battery carrier parallel wasnā€™t as bad as I thought it would be, for the driver I simply carved down a Q8 driver a little and swapped the FET for an Infineon then flashed Anduril. Close now! :smiley:

Edit: forgot to mention that I removed the brass donut connecting ring on the Q8 driver and put the brass button from the GTā€™s driver in the center.

Nop, not glued, only snapped in! Fits perfectly and doesnā€™t get out of the place :wink: Been carrying it for some days in this configuration and had 0 problems wit it, including no accidental activation!

I reckoned before that a Q8 driver would be a close enough fit, but making the carriers parallel is a good job! :+1:

Looks like, on some older 30Qā€™s, it does some 5040 lumens at start, makes 1.58Mcd in a 5M test. If the weather allows Iā€™ll try to get a 30M lux test tonight and a beamshot or threeā€¦

I changed the lens in 2 Convoys this evening.

First was my S3. It has a CREE XM-L2 4250-4500K LED and an AR lens. The beam was not the best with lots of artifacts and a greenish ring. I didnā€™t use it much, except for outside. I tried switching to a non-AR lens and a different reflector, but the beam was not much better. Then I decided to make a diffused lens from some acrylic spacers that I kept from a storage container:

What a huge difference that made! No artifacts and I even see some rosiness now.

Second was my S2+ clear (silver) with a Samsung LH351D 4000K 90+ CRI LED. Iā€™ve worked on it before to clean up the beam with a different reflector, but it still had some artifacts. So I replaced the non-AR lens with the same acrylic lens and it made a big improvement, but made the beam too diffused. So I took the AR lens from the S3 and sanded one side with 60 grit sandpaper. That turned out to be perfect - no artifacts, but still had some throw.

Left S2+, right S3:

Sure I know Iā€™ve lost some lumens doing to this, but itā€™s worth it to me to have great beams! And after all, these are EDCs, so the emphasis on beams is more important than lumens.
