What did you mod today?

:open_mouth: a glowing cube!

A phone shot from my SE, about 10’ from the wall on level 3 of 7 in the X5… this is the 5700K XP-L2 from Arrow.

Hot
spot :slight_smile:

You will find it here.

  • Then on bullet 3, and you will see a short clip

Next year, of course :wink:

Nothing too big ……I simply gave my Thorfire C8s a make over because it had started getting kind of run down looking after having it a long time and also using it a lot.

I stripped all the Anodizing off with some aluminum cleaner (a mild acid basically) and then gave the Bezel a good rub down with some brass and silver tarnish remover to get it nice and shinny, I then lightly polished the rest of the light to give it a more velvet or silky look. I never put a piece of sandpaper or any other abrasive on this one other than the Tarnish remover and used a 100% cotton rag to rub with by hand and was finished in just over an hour.

FET driver … XP-L HI V3 3C on Noctigon and spring bypasses on both ends with 20awg Turnigy.
Making 6.71 amps and 1461 lumens and looks like this…………

(could not wait for the new year :innocent: )
Thanks, I looked it up and found that the 10 euro bill also works:
365nm: 278nm:

Amutorch JM70 with TA driver :

Stock driver :

Had to add an e-switch, glued to the driver. It is perfectly aligned with the rubber boot :slight_smile:

Unfortunately, even with fine tuning of the reflector it doesn’t out throw my Olight M3XS (smaller reflector).
I got around 90% of the Olight throw

EDIT : I put a dedomed XP-L (unknown bin/tint) and now it throws as well as the M3XS !
EDIT2 : Now with numbers :
Stock M3XS : 250 kCd
Modded JM70 : 280 kCd

Finally modded my Foursevens Mini mkII :slight_smile:

It has an aluminum pill , that accepts a 17mm driver and a 14mm (i guess , 16mm doesn’t fit) mcpcb .

  • Reflowed a sst-40 on the stock DTP board
  • Changed driver with a 17mm fet-only driver w\ Biscotti firmware , and re-used the small brss ring so tube can make contact with the driver (see pic below)
  • For now i used the optic but i plan to use a reflector

Right now i set driver at 5 modes with memory . At turbo it makes 1620 lumens @ start , and of course it get’s hot in seconds :wink:

robo, add me to your refinishing service list, I’ve got a hundred lights that could use a bit of a facelift. :smiley:

Haha yea I got a few more that could use it also , but as you know it is time consuming to do the strip and polish stuff.
Be glad to send you some of the aluminum acid I use to get you through a couple of your lights though. :smiley:

Today I swapped the emitters in my D4 for the fourth,and hopefully last, time. After I made a EE6 and a Sofirn C8 with the Luxeon V, the Nichia 219C 4000K CRI92 tint in the D4 looked bluish to me.

So I reflowed one of Led4Powers MosX 4040 Quad MCPCB’s with Luxeon V’s. If it was a pocket rocket before now it’s insane, the heat is almost instant, in about 3 sec the head is to hot to hold. The amp draw on a VTC6 is 15.93 A @ startup.

I think the Luxeon V is a great emitter with a good combination of tint and output, and the MosX MCPCB’s are easy to work with but they do need a lot of heat when soldering the wires.

Happy New Year everybody :partying_face:

EDIT :

On a VTC5A I get a max amp draw of 22.4 A

So that’s something around 6000 lm. Crazy!

New light built: grey s2+ with 4000K luxeon led. LD-A4 9Amp with Thermal Enhancement Kit. On the other end ILC-0 with 4 rgb leds.

g_damian that is really neat. Saw a similar build in the DIY tailcap thread a while back and been wanting to do it. Already have the slow fade LEDs. What resistor did you use?

Happy New year khas and everone else Too.

Thanks :slight_smile: I used whatever resistor had been installed (because originally it had ice/blue leds). Just checked that it is 1.2K. Current is 0.9 - 1mA, depending on the colour. I wish there were less red in colour rotation.

The high amount of red is because the chip inside the colour leds receives a too low voltage in this application, I found. If driven properly (which will not happen in a lighted tail), a different colour rotation appears with less red that make more sense.

I see, thanks for the info :slight_smile:

g_damian, you could try to remove resistor and put 0 Ohm jumper,~1mA current consumption is limited by LD-x4, so it should work better without additional resistance that causes voltage drop.

I guess it counts as a mod, it was too easy though (well, after getting in)

I got my Lumintop BLF GT on Friday, the emitter was the XHP-35 in 4000K tint. For me, that’s just too warm so I removed it and used a cooler tint (re-purposed the HI from my Barracuda). It’s now a more pleasing to me white/cool-white and the throw went up from 1102.5Kcd to 1237.5Kcd (Yes, that’s 1.38 MILES)

Beamshots in stock form, with the 4000K emitter…

610 yds is nothing…

I believe the trees behind the white barn are around 738 yds away, this shot taken at 112mm, full optical zoom on my G1X

Mondo Hoss light, epic win for Lumintop and the BLF team. Kudos! :smiley:

Should probably also state that with an 18GA loop in the negative lead stream at the MCPCB, top of the ramp is doing 1.93A at the emitter and a double click to Turbo is doing 2.45A at the emitter.

The lux testing above was done outside at 15M. :wink:
