Today i have modded a trustfire 3t6, i changed leds from 3x xm-l to 3x dual nichia 219A.
A bit too much work in the end I’d say, since it ended up having a donut hotspot :~
I had hoped that somehow the 3 reflectors would help against that

You really shouldn’t be getting a donut. I think if you try getting the reflector lower, or the emitters higher. Thin centering discs or paper gasket. Maybe sand down the centering rings you have. Did this light always have a donut?

It sounds like he put two nichias in each reflector, and that’s what’s giving the donut

Made a Convoy C8 with dual channel 105C-based driver running bistro, 10x AMC7135 + 1x AMC7135, and XP-L HI V2 3D. Played around with it for a short while, didn’t like beam that much. Would have done further adjustments, but than I saw a big black spot on the DIE. Bummer. Hadn’t had that happen until now. What could cause such a failure? The LED was bought already mounted on 20mm noctigon from IOS. Normally I reflow them myself…

Usually it means there was something on the dome/flat part like dirt or something that burned a hole in that spot. Probably not anything to do with a reflow.

Have you heard about baking LEDs before reflow? Cree and Nichia recommend that if the LEDs were stored in a too humid environment or if you assume they could’ve been… Otherwise they can get destroyed during reflow process. Not saying that’s the case here…

Nice mod. It looks like you have been to the OL or RBD school of modding.

My current and or voltage measurements are only relevent to anything that I measure.

No pictures but I stripped the driver in my brand new Archon D22, LED+ lead straight to the top of the battery spring and LED- straight to the body. Also swapped out the XM-L2 for an MT-G2 on 20mm Noctigon. First diving light and it's pumps out some light underwater.

(actually two days ago) I put an SSL80 4000K 92CRI into a very cheap AA zoomie (from dx, FT has it too). I used a 6-chip AK-47-C1 for 2.1A current. Output is 300lm flood, 150lm spot, and I set the focus a bit above the die in the dome so that it is a smooth round spot instead of square.

The mod did not go smooth, the driver floating under the pill is not ideal during assembling, the ledboard+solder blobs were too thick so that the plastic clamping ring that pushes the board onto the pill hardly has a grip inside the pill cavity. The switch mod was not done well either, but with 2A max that it should survive.

The result is really nice though, like it a lot! Smile

Replaced the 219A in my D25A with an XPL HI V2 5B4 and added a bit of solder to the positive contact so I could use a flat top Efest 14500. Warmer tint, higher output, runs cooler.

Also put the same LED in my Kronos X6 and bypassed the springs.

Unfortunately I only have one left and it doesn’t look like I’ll be able to get anymore.

I put a fet+1 in a XinTD C8 7135 that has a XM-L U3 1A led in it. It’s a little brighter.

I received an xtar charger that failed when the AC adapter was plugged in. Xtar warrantied charger and I told them I’d destroy the first since I couldn’t send it back as they requested. The shell, messed up circuit board and sliding contacts remained, so, I built a charger/light combo using a 4056 charger and half (4.2V) of a messed up MTG2 LED. Big Smile

The left ‘bay’ is the charger and the right bay has a 3× 7135 driver powering the LED. The ‘diffuser’ is piece of a toothbrush case stuck down with double sided tape. Big Smile

Part of the reason was that I didn’t have a single 26650 light so instead of spending money…

I installed an A6 driver in a Nitefighter 502B. Driver ring was jammed so I drilled the driver and left it in place. Filled the gap with wire and soldered. The spring actually needs to be clipped but I chose to put a thicker Oring and all is well. I really do like the A6 driver. Wish the Bistro was available. Nice light now!!

Built a Trustfire Mini 01 triple today with some spare parts i had.

Copper & QTC pill in the tail for variable output, Also made a copper head spacer.

I didn’t realise the 3 XP-G2 were different tints until i had it put together, doh – i think there’s maybe a 2B, 2C and 1A in there, not entirely sure. :-/
This bothers my CDO so i will call it an intended tint balancing feature Wink

Also ground off the keychain attachment and installed a magnet in the tail and some heatshrink around the body.

Nice mod CRX! I have some QTC pads waiting for a mod still.

Thanks djozz, yeah the QTC pills come in handy for when you accidentally break drivers.

Is the whole light copper or is that just the lighting?

TBF tint balancing feature. I like it. Maybe make a bezel cover with single hole so you could rotate it to select you desired tint Smile

I made a butter knife into a steak knife in four minutes to demonstrate the effectiveness of my Ken Onion Worksharp .

Have I mentioned how much I like this tool ?
