Bloody hell! it worked! If anyone less of a numpty than me wants to bunch them up,feel free.
The light started life as a LSH-S (no. 123),modded by "the Fire",to have a Lux III at 667ma. The Kroll spring Hi/Lo from "gadget lover" is fitted giving it more practicality.
I put a Fraen LP optic in,at the same time installing 3 small GTLS tubes around the LED.These are only 2mm by 12mm but were still snug to fit.
I made the rest myself in the workshop. I love it,can't see me parting with it,but Charlie might say different when my VIP turns up!
This is my workaday EDC,never without it.Any questions,feel free to ask.
BIG thankyou to "JPEG" for his help
Phil.
