bump ? 
that was a useful bump
well my flashlight was finally ready to shine but you know me having a xp g2 in copper overdriven like X3 or more around 5 A with an Fresnel lens 100mm diameter with around 0.4 f was not satisfied. The beam was good strong and with a big hotspot. Around 200 000 lux but still I wanted more, so before we go in beam shots I have one more little modification to do.
Reflectors +Aspheric
When I marry reflector and aspheric together for the perfect throw,
and the waiven start to be little bit jealous….
I took this reflector :
curious like always how it will work. Diameter 100 mm, not smooth but not orange peal type either, it have somehow strange reflecting pattern, but it work relatively well.
Better than fresnel both in lux AND in total lumens it output and I like this fact.
But it was not only this I have another idea in mind to that had to experiment.
I took the aspheric of my UF-T20 and this time I had the luck by my side.
In theory I wanted to kill the spill one wide reflector have and recycle it in the throw, and this can be easy obtained in this way :
Normally in a reflector the throw numbers are the area in yellow and in the middle there is a missing part in light that looks like black hole. In my setup there is added the lux throw from aspheric so total throw of the system is reflector throw + aspheric throw like there are two separate setups IF is done right way.
I started the work:
Even the reflector alone it was better than the Frensel in throw.
I continued with the plan>
Lucky for me I find an very elegant solution for my new setup
apart that it was very difficult to focus, (three deferent parameters in one) it was a big success for me. The max throw I was able to add to the reflector was around 1/3 of the reflector. On one fresh 28A Samsung I get around 350 000 lux from a xp d2 with dome. Without dome it should go around 700 000 and I believe with three 20R Samsung and some fine focusing I could get even more maybe. It would be very cool if I get my RBRZM lux numbers(just over 1 000 000 lux) in a smaller package AND with a lot of lumens too(around 900). So throw and lumen in one and good run time in other modes all in one scratch build make me very hapy.
Beam shots
I have limited view from my house. I have like 4 or 5 distances I make comparisons for my lights. They vary from 15 meters to around 250~300 meters
Waiting for the night to come
This is around 15m
This is control shot
Around 50 m
Around 150 meters
Around 300 meters

Control shot
sorry for my low quality of photos and posting but this is a race against time. If i find more time will post better shots and maybe some comparisons with convoy M2 because that is my only flashlight that you know well enough to get an idea.
i have to work on my flashlight to make it decent looking have some nice ideas but not sure on time. functionally its working 100 for now as it is and it looks very reliable from 2 week test i done.
but i intend to take my time with this, so even if I have a lot of free time(which i don’t have), I do not intent to rush with this.
