What did you mod today?

wow, extremely impressive Tom, looks like a very neat assembly, and that is 2000 lumen per led which is a big achievement for a relatively compact multi-led light.

Would like to see that beam in person :partying_face:

Tom. That is just plane nuts. What a fantastic effort and execution. Hope the driver problems get solved. :beer:

Thanks all! I'll have to see what I can do for beam pictures. These are E2's, so 5700K or so. I'm gonna try to take lumens and throw measurements this morn.

pretty little LED

Nice to see a mod with the XQ-E ! R2 sounds like a good bin. That Liteflux flashlight is from before I was a flashoholic :slight_smile:

They are actually bigger than S2 reflectors at 21.2 mm diameter with the total head width of 99.2 mm. S2's are about 18-19 mm. I used 16 mm Noctigons with only the 5 outer most needing a slight sanding to fit at the edge.

Measured throw from 5 meters: 155 kcd (787 meters)

So it's a thrower, I mean a flooder or throoder? This is why I wanted to go big with a head like this - I knew the throw would do well, but didn't expect to break 100 kcd. Ganging triples/quads is easy, like the Meteor or Vinh's custom 30K+ monster, but it's mostly a flood light then.

Why not just go with a single COB led and get the same lumen output from a single chip + large reflector?
Pretty sure it would be more efficient than multiple XHP50s, so less heat and battery drain.

Pretty impressive monster you got there Tom. Surprising results also for such a shallow reflector. Sheer power does the job. How much did it cost to build this?

Dunno much bout COB's. The voltage of XHP50's is perfect for the 2S3P batteries. I'm not an EE and can't custom design boost or buck drivers, for sure.

Most of the cost is the LED's - roughly $150 $140 for bare LED's, $22 for the Noctigons, ~$80 for the host (can get it for $62 or so now), maybe $15 or so for the driver and wires, so $257 total.

I just modded my perfectly working Utorch UT02 into a fancy paper weight.

I wanted to change the resistor to gain more output. First I had a hard time getting the driver out ( should have stopped there) found the resistor, it was so tiny (or stopped here). Then I remembered when I tried to solder moonlight parts on a LD-2 driver (definitely should have stopped there). When ahead anyway and ended up with a dead flashlight. So from now on re-flowing emitters and changing drivers is all the modding I will do, that is of course only until the memory of this failure have faded and I think “how hard can it be”.

I think there is a what did you break today thread. If not there should be. I have a fair amount to contribute to it.

Don’t give up khas. Get one of these, changed my outlook on what can be done.

Modded mine with dedomed xp-g2 and TA driver running Narsil , i couldn’t be happier … making 292kcd now :smiley:

Brinyte B158

Part 3. Used 1” and 2” hoke saws wrapped with tape and sandpaper to ream the copper fins to fit and made a jig to sand the spacer rings down to an even 1.5mm (+/-.02mm). Just slip fitted for now. I also turned the wood down a few more mm.

No? Yes indeed.

Lexel, I thought that I was the king of blackening dedomed leds in zoomies but I just found the master!

Wow TomE what a monster. I think RBD and Tom should’ve made separate threads.

I was also thinking Level did a good job on the black out.

When it’s done I will but for now it’s what I did today.

I like my Lumintop tool AAA because of the small light with clicky switch. I don’t like twisties. But for a magnetic tailcap I need to sacrifice the good switch. Then I putted 3 small neodymium magnets on the clip and secured it with heat shrink tube. Now I got clicky and magnet. Done :slight_smile:

Haha little trick :+1:
