What slice?
May I introduce BLF Q8 Janus:
2 Heads, one white, one with red, green, blue and amber LEDs, heads and color LEDs individually controllable.
The modified MCPCB with XP-E2 color LEDs, and my driver which is used in both heads. In the white head populated with FET + 7135, in the color head populated with 4 x 7135 for each LED. MCU is Attiny 841. Full ramping UI of course. The reflector bottom had to be grinded a bit to make room for the outer LED wire pad. Reversed MCPCB polarity (batt+ at the outer trace to keep grinding at a minimum).
Cut a solid 6mm brass rod and soldered a spring on one end in order to bring batt+ to the rear head. Used tape to isolate the rod and drilled a hole in the tail PCB.
The threads at the rear end of the battery tube are too short to reach the driver board so I made cut outs (for the PCB screws) to a copper ring and put this ring on top of the PCB.
Btw., this is how I program my Q8 drivers:
You are Darth Maul.
Actually my initial project name was “lightsaber”. 
Impressive, can you cap off either end and have it work as a single light or is it fixed in this dual config now?
:laughing: Very cool.
I put a Samsung L351D HICRI led in my D4 Emisar and M43 Meteor lights ;)
It’s only screwed and can be separated easily for 2 individual lights. I just unscrew the rear head and pull brass rod and copper ring out.
How’s the output and tint of the Samsung Emitters?
I’m curious about the beam, I don’t think I’ve ever read any review/tests with samsung emitters
With the medium amp draw from the meteor it seems like a pretty ideal light for those LEDs.
All hail BLF Q8 Janus, and of course FM. Nice. :+1:
Wonderful weird project Flashy Mike!
That is lots of designing and building!
@maukka
Thanks for the links

@Flashy Mike
Very cool Q8s!
@djozz
Your Sofirn C8 with grinded bezel is very cool!
That’s a very cool mod, Flashy Mike :+1: 
Nicely done Mike, I was about to post up something but you made my little tinkering project look like a popsicle stick cabin job, 
Way to think outside the box, very sweet!
Thanks, everybody!
Oh man, I have to follow that wild mod?! I trimmed and shimmed a reverse click switch so my SingFire-75B would tailstand, put a piece of diffuser material between the reflector and the lens and pencil modded the NMM cap… It is my new go-to indoor light for after dark toilet trips.
My first published mod, go easy guys…
