Looking good that collar... Why would you not sell it to people? This is budget forum so you could make something with acceptable price to us and earn some $? I am first on waiting list...
Do you use welding mask when centering this collar? Or maybe moonlight mode only? I would have to use some eye protection for this because I mostly have single mode drivers.
Yes indeed XP-E2 R4 from IO are cool white with 1C tint(a bit greenish tint)...
Night picture taking is hard and with phone camera even harder so I should not judge the picture.
Illumination supply carries XP-E2 with 1D tint if you want to try something similar...
I don't think Andi gave correct data... It would be lucky if it throws 300 kcd with driven XP-G2.
"I bought the X7 to mod it into a aspheric thrower with a hard driven XP-E2 + 75mm lens"
Tried that in Xsearcher aspheric and if you find good aspheric it will be true laser like beam( I don't like it since it is smaller and I got even lower results than with hand selected XP-G2 2B (the brightest out of 20)
My advice is:
- No point of driving XP-E2 more than 2.8 A (no results and heat will be enormous if you will tune it up with more chips)
- Stick to newest XP-G2 S2 (brightest XP-G2) and order at least five pieces and select the brightest of them(you will surprise how much lux you can gain with right selection of emitters)
This is mine 450KCD(with lower performing brothers I had from 380+) Xsearcher with hand selected XP-G2 R5 2B driven at 3,6A heavy fog( I don't want to tune up further because it is single cell light)
I will try to made XP-G2 S2 1A (which should outperform this setup up to 10% or more if I find brightest among lot of them because 2B is in its upper performing class. If you don't understand what I talking about read here about led bins and performance deviation http://flashlightwiki.com/Cree )...
In fact I have 6 pcs of them I am just to lazy to start...
Looking forward for your build but I think it will be extreme hard to find good aspherics for X7. Good luck.
