Modified M20X W/aspherical lense & custom optics Compared beamshots - Very Pic heavy!

Greetings! Was messing around with an aspherical lens that I purchased to fit with my M20 SX. Below is some documentation and beam-shots I'm hoping will be useful to those who have interest.
First, the aspherical lens is a 27.2mm lens that I purchased from las3r here on the forums. Quality is solid, and it was shipped immediately and arrived well packaged with US tracking. I shared this same feedback on the cheers section – and any interest in these lenses can be found here: http://www.candlepowerforums.com/vb/showthread.php?328374-Aspheric-Len-s-sale-USA-Canada

Now moving forward, I'll post what I've found and am totally open to an pointers on what I can do to get an even tighter focus from my set-up. I found that I got the distance focused quite well, but at 100 yds or so, the 'square' beam really opens up. I was hoping for a tighter square – but perhaps it's because I'm running it through an xml??
The next pics are a quick description of quickly rigging the light for temporary purposes – but I must say that it was very easy and is actually quite secure. I wouldn't advise however taking the light into any water as the threads towards the top are only about 1.5 turns onto the thread…

Here's the light itself:

Next is a shot of both reflectors, the aspherical lens, and an inner spacer made from duck tape that the aspherical lens sits on top of, as well as an outer piece of duck tape that goes around the inside of the lens to secure it inside the light.

This is the inside of the M20 with the reflector removed

Popping the lens out -

Placing the lens on the top/outer side of the flashlight where the strike bezel would be – it rests on top and there's a little room for the lens nut to go on top and get just enough turns to secure it in place

Next, I took the inside duck tape spacer which is a little larger to give the aspherical lens the proper height from the led so that it's focused and placed it inside the olight. I cut it to fit the diameter – then placed the aspherical lens on top.

I then took the other piece of duck tape that I cut to size and put it on the outside edge of the aspherical lens and tucked it inside the flashlight so that the lens would be secure.

I then screwed the modified top piece back onto the body. I made sure not to tighten too hard…

So… How did it work??? Well I don't see this as a deft – but then again, maybe I can do a better job of focusing, or perhaps combining it with another reflector, etc… again any suggestions welcomed. I thought it certainly did better than with the smooth reflector alone – but my findings say that the custom optics that I rigged, focused the beam a bit better and it was in the form of a circle.

The first set of beam shots are of a car at about 100 yards. Any LEO's can get some representation of how much you can actually see. I set the ISO to 200, but on my camera, I can't adjust the shutter speed… Looks like time for a new camera. Anyway, in my opinion, the actual light that I saw was a bit brighter than what these photos represent, but they're not too far off.

Also to note – all flashlights are running off of 18650 batteries – fully charged. I'm not doing lumens testing with instruments – it's what the eye can see. All lights set on max modes & rated as follws:

M20 SX = 500 lumens
Zebra Light SC600 – 750 lumens
Jetbeam RRT 3 triple XML – 1950 lumens

M20 SX with orange peel reflector – 100yds

M20 SX with smooth reflector – 100yds

DSCN6175 by RCSHAR, on Flickr

M20 SX with aspherical lens – 100 yds

DSCN6165 by RCSHAR, on Flickr

M20 SX with custom optics – 100 yds

DSCN6167 by RCSHAR, on Flickr

Zebra light SC600 – 100 yds

DSCN6164 by RCSHAR, on Flickr

Jetbeam RRT3 triple XML 100 yds

In the next series, we're looking at around 50 yds to where the two smaller trees which are just behind the larger tree. All of these are of the M20 Xs with the different configurations.

For the next and final group of beam shots – we're looking at approx: 35 yds. These definitely show the beam profiles at such a close range.

Hi - I tried to see if there are any comments on this thread and see it was moved? If there's an administrator on here - can you please direct as to where it was moved to & why, so I post additional info in the correct area? I had seen similar posts/modifications here, so I thought this was the appropriate area. Thank you
