FW3A mod thread. Post yours!

Manker:
Front flat to optic opening is 6.66mm, Front to legs end 8.34mm

Carclo:
Front flat to optic opening is 5.06mm, Front to legs end 7.54mm

So 0.8mm.

Maybe it would be possible to get MCPCBs from Mateminco?
0.8 mm…doesn’t seem impossible to find for someone with the skills and inclination of CRX. :slight_smile:

This is true :smiley:

I was thinking of three white flats with three individual reflectors, but keep that quiet :innocent:

Why? Its not the optic.

Last night I tried a couple more LED setups in my FW3A

  • Triple LH351D 90 CRI 4000K - I was not impressed. As expected, due to the floody emitter the hotspot was much bigger, but with much less intensity than XPL HI. Ultimately I decided LH351D was simply too floody and quickly swapped it back out of the light.
  • Triple XPL HI - composed of two 4000K 5D and one 5000K 3D. Much better. I also added Lee 279 minus green filter for even better tint.

Thanks for the report. I was thinking about trying the LH351D… but the reported flood is not what I want.

Mixing the XP-L HI’s sounds good. Gonna give that a try. :+1:

Teacher, if you got the Samsung triple available you could try them and then slice them for less flood?

@ Umpi2000 … Good point…. thanks for the suggestion. :+1:

Still no light yet but I made these.

I had a little go at making some rigid glow gaskets using magnets ;)

LIT glow powder mixed with UV glue.

Aqua blue, aqua blue & green, green.

I'm also trying out a couple with silicone.

those looks really nice, CRX

Thanks mate, yeah not too bad for my first attempt :+1:

Yeah… those look great!! :beer:

Too bad only 0.001% of humanity has CRX like ninja modding skills.

I hope it’s 0.001%.
I’m afraid it may be as low as 0.000000013%

Good work !
I knew you would make something like this. :smiley:

Updated the first post with pics of the latest work and beamshots… hope ya’ll enjoy!

Thanks for the update, looking good too. :+1:

Got a question: It that a fly tying vice holding the driver in this picture??

I got impatient, so I modded a FW3A XP-L HI to use 219B instead. It’s a sw45k triple now, and it’ll probably be my daily carry light for a long time… because FW3A is my favorite light and it’s awfully hard to beat 219B for tint and general beam quality.

Overall output is very close to what Bob posted… but mine is about 3% lower because all my measurements are about 3% lower than his. I think we jut have slightly different calibration on our integrating devices.

  • Moon: 0.1 lm
  • 1x7135: 93.5 lm
  • 8x7135: 622 lm
  • FET: 1384 lm (with a 4.0V cell)

This is measured with a tube calibrated to match some reference lights from maukka, so I think it’s probably pretty close to accurate. It’s nice that the variation between people’s measurements is so small now, instead of being as much as 50% off like things were a few years ago.

Anyway, for the time being, I basically optimized my EDC light to taste as much as possible. Time to go work on something else, I guess.

I was at that point 6 years ago :person_facepalming:

Yes it is! I’ve been using it for years for reflows, dedoming, etc. When I was a young teenager I would use it to tie fly hooks but haven’t for many years.
