Not a physical mod but still tons of work yesterday.
My wife came to me a few weeks ago needing a light for a very specific use;
Wide even beam with no hot spot
Red light
Single mode
Small host
USB rechargeable
Like most people I try to provide everything my significant other needs but there’s some things we’re just not able to provide like unlimited money or things not in my field of expertise so when a need I can perfectly fulfill comes along you just gotta love that feeling. Yea babe, I got this!
So I ordered up a utorch s1 mini, got it stripped down and got the driver board out then set to work making up a driver for it. This is the end result ordered from oshpark.
Interesting bit- the heart BATT+ pad is a library part, after I drew it with the line tool then cloned it and changed that to bStop for the mask then needed to reposition it a fraction of a mm and all that going to crap cause it just wouldn’t move right as a group I wasn’t doing it on the board again so I just drew up a 5mm heart shaped library pad and now I can drag and drop is as needed lol.
Final specs:
Osram Olson ssl-80 in the deeper of the red nm choices
7135x2 with modified Tom E “E-switch 13” FW. Single mode medium with the hidden strobe replaced with hidden max (press hold).
Sub 16mm custom driver design one off for my wife
Uses a gigantic 3x5mm switch that I have a million of.
No thermals on the 7135 tabs with solid Cu pours under them for better heat management cause of the low vF of the red LED.
Update: I lost the switch bezel so I made a new one, being that it’s our 6th year married I’ve been incorporating copper into every gift I could and this was no excepting. I feel like this one hit the bullseye (you’ll get the pun in a sec).
Btw this was done with a hand drill, a pair of pliers, a hacksaw and some small files.
380 round, lead drilled out, a tiny sliver cut off.
Yesterday the new Osram CSLNM1.TG leds arrived from led4power. Putted in one to my modded Convoy S8 and one into my GT mini. Some pics and beamshots:
Convoy S8, S2+ SMO reflector, AR lens, 3,15A. 9x7135. It makes 573 lumens and 30800 cd.
It is slightly smaller than XP leds
GT mini with Emisar D1S reflector. You can see the beam thinner as going away from light so it need to raise the reflector a bit. Making 219000 cd with unfocused reflector and GA cell to not overdrive the led.
I bought these soldered to MCPCB but I using paste with bare leds. With size I mean the complete led size smaller than XP centering ring cutout. Not the die.
This emitter was my test led and got slightly burned on the edges of the phosphorus during some max power tests, that’s what the odd color is in the reflection of the die. Even as such it still performs well as well as expected (i.e. nothing to write home about but it’s still cool as hell)
XP-L HI (stock) 29,690kcd damaged XD16 5700cri 25,700kcd.
I have 2 more 5000k 70cri emitters to play with too.
Throw is comparable with C8. Here is the picture with Convoy C8 with CREE XP-L HI V2 5D at 2.7A, SP32A with OSRAM KW CSLNM1.TG at 3A and stock Acebeam EC35 at 3.3A. Around 2.5 metres to a wall:
