What did you mod today?

Good job MascaratumB! It seems the cheapo flashlights are the hardest ones to mod.

For the sake of completeness:

Measured it today at 410 lm, beam distance 87 m. Nichia 219C measurement (by Klarus) were 395 lumens and beam distance of up to 77 meters.

Thanks NeutralFan :wink:
Well, that was, at least, weird to mod :zipper_mouth_face: Press fit, plastic pills and that combination of driver/pcb/pillā€¦.was fun :smiley:
It trows well with the Tool AA + XML2 but it is a light for fun, mostly :wink:

Welcome to the club of 219B sw45k lights, EagTac D25A!

(no clever tricks, just brute force)

Iā€™ve been super busy at work lately but finally got some time this arvo to work on this. My soldering and execution is not real good so this is kind of a proof of concept. As a result i had bad connections etcā€¦ and it took several goes to get it to function properly.

New led mod :weary:

That must have hurt, might as well tell the story

Ouch!

Also: What did you BREAK today?

Let me guess. This new type of led mod throws a shadow into the lightā€¦. :laughing: :laughing: :laughing:

Sorry I couldnā€™t resist. Better luck next time CNCman :wink:

I had a simple yet satisfying evening swapping drivers and emitters in two hosts:

S21A, LH351D 5000K, 20mm, SST40 6A

C8+, SST40 6500K, Mtn FET 17mm

This is actually my second S21A that just arrived from Mtn. Electronics. My first S21A fits all my 21700s but this one has a smaller inner diameter. I added an older convoy pocket clip but sealed it with heat shrink. It needs 6mm hex fasteners. I think the S21A is perfect for the LH351D.

I had my 5000K in the C8+ but the SST40 has quite a tight beam with this reflector. After reading about the choices of an XPL-Hi or an SST40, I chose MORE LIGHT with perhaps, a little less throw.

Is that some sort of new UV or IR led. I canā€™t see anything but a black spot. :stuck_out_tongue:

You guys are cruelā€¦

Nah, itā€™s just a dark-emitting diode, or DED.

Yeah, it dedā€¦

So it emits dark energy?

First mod in a LONG time. LED swap on a 2020 model Jetbeam RRT01:

Shaved LH351D 5000K from AEDeā€™s last batch

I cut flat parts on the centering ring so it would not ā€œrockā€ against screw heads and clear my solder blobs. It sits nice and even now.

The spare garden hose washer you get with sprayers and hoses to work with bezel.

Very nice result. This is on high, in hot spot, using stock glass. If I replaced the glass it would be even lower DUV.

Today I sliced LH351D in Wurkoss F11.

It gets more throwy, warmer and less green :slight_smile:

Been noticing some posts on sliced 351D's - sounds all good, but I assume lumens is down. Any know the #'s of kcd increase, lumens decrease?

djozz ran a test with the 4000K version and reported 18% lumen loss and 50% throw increase.

Lower DUV by >= 0.0035 and Lower CCT by ~500K is pretty consistent too

this review says the 2019 gets 680 lumens on 18350

it seems the LH351d only drops output by 6% compared to xpl (ceteris paribus)
