@McGizmo:
About how well would you guess your three shooter stacks up against high power incan lights? Is it a SF C3 HOLA replacement or are you up into the M4+ league?

Thanks for the answer.
I agree that a P2 flux is really impressive at 350, and when you look at a p2 at 700mA putting out 1.7 times the light at 114 lumens on the low end of the p2 scale it is mighty impressive.
Keep up the great work McGiz!
enLIGHTenment,
I really have no idea. I really like the looks of the 3shooter and it was a fun challenge to design and then have the parts sampled. It is not friendly in assembly nor is it optimal in terms of thermal relief. I got a couple heat pipes from Newbie (thanks!
) but these require depth on the Z axis to host. If one accepts the nature of the beam from a side shooter, there are all kinds of new clustered configurations which can be considered. If the LED is located at the perimiter, its sink can be the head itself. As an example, consider the dwg below where there would be 4 LED's in each corner and then a 5th one in a central reflector:
It is conceivable that such a package could deliver 500 lumens in an impressive moderate angle spot. You can get goofy like this XR-E 13 LED flower cross section below:
The sink planes/ partitions could be an extrusion of Al and then you would mount the LED's run the leads and install reflector canopies. Instead of hot pedestals, you would have the heat transfered to the web and shell of the extrusion. I haven't illustrated with a beam shot what happens when you slide a reflector canopy aft of focus but you can get an interesting wedge of light distribution.
A commnity of LED's could work towards an aggregate beam that would be more than the sum of their parts in terms of diversity and distribution. The Z axis of each LED need not be parallel to the others either. I would assume that if we see LED based headlamps, we won't see a simple clustering of like minded individual LED's but some type of community diversity and a delegation of different illumination chores.
With clever minds and computer modeling, who knows what might be brought to bear?!?! Let's just hope the patent industry isn't party to pooping! :nana:
EDIT: an underlying consideration that I think I should point out is the fact that the XR-E having a narrow viewing angle should be exploited and taken into consideration as an advantage to capitalize on as opposed to a short coming to be worked around.

AW, apart from difference in sidespill, how well does the Cree optic "throw" compared to an McR+Lux combo ?AW said:
Cheers !
EDIT: McGizmo, are the McR-17XR already available ?
What is the dia and height of this reflector ? Thanks !

I have a FFIII and would like to know the size of the reflector in it.
I would also like to know if there will be a reflector this small that would work with the cree in this light.
How about a deeper reflector of the same diameter. Would that work? Maybe one could be used without screwing the bezel down as far?
I am hoping that I could use one of these in my FFIII becasuse I like the small size for EDC.

I wonder what the beam would look like with no reflector at all? The LED could be very close to the lens, and it would be quite floody, but it would give a very wide beam.

Just found a Luxeon reflector could be used with XR-E. Although the beam isn't perfect but could be used well.
Reflector's data:
Photo:
with XR-E on Star MCPCB: (Cut the two small dots and it'll fit with the XR-E's square base)
Some beam shoots with Fenix P1. XR-E is running at 350mA. The distance to the wall is about 60cm. Sorry for the poor photo with my old DC that could not switch to full manual mode. I hold the XR-E with one hand and DC with another, thus the position moved as you could see. And the distance isn't enough to include the full beam.
The beam pattern is similar. The side spill is almost the same size(not clear on photos, XR-E is too bright?). There's a small fade ring around the center spot with XR-E.
XR-E with the reflector on left, P1 on right:
EV -1.5
EV -0.9
EV -0.0
EV +0.9
EV +1.5

What reflector is that? Where can it be bought?

NetKidz: Yes!!! tell us where to get that reflector!! It looks great! Nice tight spot!! Impressive for 350ma!!! (I want to build a quad mag with these!)
I'm in Taiwan and got them from a local manufacturer about $1.2/pcs. It's plastic coated with aluminum. The LED need good heatsink, since they said the temperature is up to 75 degree C for the material(I think it's too low). I test the XR-E only with Star MCPCB for several seconds about 1.8A and the reflector base melted a little. If anyone is interested, I could buy some and ship worldwide.
I take another photos today. LED to ceiling is about 2m and the fluorescent light is about 1.2m long. Side spill is larger than the photo and doesn't clear. The current is about 350mA. I may have wrong current setting yersterday.

Nice find netkidz, do you think you can find something a little more heat resistant? Hopefully the manufacturers will catch on to this new led and start offering more variety of reflectors.
Do you think there may be a IMS-27 size relfector (27mm) that can focus the CREE?
Thanks!

melted!! EEEK! 1.8amps is hell of an overdrive though!! and the mcpcb I've heard is really an insulating pcb that doesn't conduct heat as well as it should, so it could be getting heat soaked fast!!
I wonder if they would survive in a mag head with 4 of the cree's at 700ma... Hmm.
I have heard that modifying the IMS 20mm does work. I know they can sustain high temps (they have in my mag mod). I wonder how they would do against this reflector??
AlexGT: I imagine that if the IMS 27 was modded perhaps it would focus like a modded IMS-20mm?

IMS 27 does not work at all. It's far too wide with respect to its height.
AlexGT,
I've also tried their 25 and 26mm reflectors but they're not suitable for XR-E. Donut shape if not modified. I've asked them about the plastic material but may not have better one at this moment.
They're not catch up with XR-E yet. I'll try my best to push them. :naughty:
IsaacHayes,
1.8A was just for test. It's very bright and HOT! I just mod a flashlight, it's about 700mA (2x AMC7135). I'll try to light it up for hours when I fix the broken swicth.

This is my first time playing with sputtering using clear paint. The results is good IMO, and I'll use this to build my bike light.
