Dereelight C2H ~ 8 Degree Optic ~ XP-E ~ 17500

+

Just tinkering around a bit;;;

I don't impress that easy, but gheezussssss!!!:devil:



4A tint R2 XP-E






beamshot inside @ 7 feet
outdoors,, you'd never think it's basically a AA size light,
great throw {really impressive setup}



there are about 3 layers of spill, it's unnoticeable unless you do a white wall

Is this a mod you've done or is this the way it comes? I can't tell from your post.

gcbryan, a simple mod I guess,
its more so putting parts together.

**The AA extension needs to be bored for the 17500 cell.

gotta say, the 4A tint is a real winner

Nice, where did you sourced the optic ?

Got it from KD few years ago...
if you KD search 8 Degree CREE there are some still avail.
It takes a bit of customizing to get it just right, nothing overly tricky.

The beam is different to anything else I have & there are zero rings
the spill steps down in layers, functional light flow w/ the XP-E.

I generally prefer more throw than flood in my lights, this does them both ~ :thumbsup:

Orbital,
Compare this Optic build vs. the P60 XM-L reflector with XP-E you discovered weeks back.

Which one throw more?

Thank you,

Have you used the TIR available from DX? I did something similar to what you have done by taking a Ultrafire BJ08A (single AA/14500 using a XR-E).

It was more or less like using a reflector except that the little collimation lens that goes directly over the emitter reduces the intensity of the spill (which has the effect of softening the edges) and adds more to the corona.

I liked the effect but it still only outputs 900 lux at 1 meter (vs 5,600 lux when I used an aspheric) . The Ultrafire mentioned is good for these kinds of experiments as it has a nice screw-in brass pill, uses a retaining ring in the tailcap (easy to change to forward clickie) and uses a similar retaining ring in the head so the reflector comes out and the ring will either hold in a TIR or an aspheric.

I'm just curious how the DX and KD TIR's compare.

By the way the DX TIR is meant to be snap-on for a XR-E. In the case of the Ultrafire it didn't fit (diameter too large) so I cut the plastic surrounding holder off with only left the bare TIR and that did fit.

hmm. very cool. this gives me some ideas :devil:

bigC, even though I've been able to get the hotspots nearly the same size,
the P60 drop-in will give more punch
The optic pulls more energy to the spill.

For an edc, the optic & the XP-E is a challenge, not impossible.
I took it apart today to test and when I put it back together, got a different result.
Optics are finicky and if your off by even a little, it'll really show.

Its mainly the challenge of doing something different
....looking to make a setup so if I take it apart, the optic/emitter distances are exactly the same
when it goes back together.


Pill/reflector setups are more straightforward to tune.


edit: I found a way to keep the optic & emitter in line and it allows me to focus in or out if needed.
Also has basic resistance.
Its so simple I'm kinda embarrassed;;; figured it out anyway

surprising throw in the C2H w/ a clean beam
