But this is what I have and it is very impressive with this lens.I did a little testing with my lens and bezel last night. No, I didn't hit anything (or anyone) with the bezel to test it that way, but it is so reflective it helps the beam pattern (maybe). 😎
I put the Melles Griot 01LAG123/066 lens on a 2D M@g driven by a Malkoff Devices 2-3D SSC powered by 2 D Duracells. Note that this LED is not fully driven with 2 D cells, and the SSC has a wider beam pattern so less of the LED light hits the lens than would, say an R2 Cree.But this is what I have and it is very impressive with this lens.
I compared to a known thrower, the Tiablo A9S, a Wolf Eyes Sniper MP-E and a M@g 85 driven with 9xAA NiMH.
The Malkoff / Lens / Bezel destroyed them all for spot intensity. Even this far from optimal underdriven SSC.
The Wolf Eyes Sniper MP-E has a wonderful pattern and amazing output with pretty decent throw. The Tiablo A9S looks weak by comparison but the hotspot penetrates the Sniper's hotspot by a not too large margin.
The M@g85 makes a LOT of lumens (the most in this test), but the hotspot is not too strong (FM MOP new gen reflector). The projected image of the LED die burns through this 1200 lumen pattern like it wasn't there at all. (Sort of like a 12 gauge vs a .223).
The Malkoff / Lens / Bezel is a very nice setup, probably close to optimal for the head diameter and with the lego capability the M@g is famous for. I really like the round clean pattern when the lens is cranked down beyond the optimal focus. It is a very tight clean spot, rather reminds me of a hollywood spotlight lighting up one small area with artifact free white light. This configuration is probably more useful than the super-throw, but a few turns of the head allows access to either. Having the bezel to protect the lens makes it much more useable without concern for damage to the coating and front lens surface. :thumbsup:
I'll have try the lens on some other combinations, but that will have to wait awhile as I need to get back to my other projects...
Thanks, Mike! :twothumbs
What's the best driver I could use for a single Cree R2 aspherical?
Very comprehensive 411 Alan, thank you!
As soon as I get a descent host put together I'll be able to experience this performance first hand.
What's the best driver I could use for a single Cree R2 aspherical?
I currently have one of Wayne's Shark / Remora available and I got the heat sink and R2 covered.
I'm in for some D-mag Nanotechnology x2
I wish the postman would hurry up with my bezel!!!!:mecry::sigh:


So what do we call stuff that nano produces?
A nano-bezel sounds like it's for what we Brits would call Action Man's torch and you guys might say is for GI-Joe's flashlight
Is this any help to you Nano http://www.glowforum.com/showthread.php?t=40

That is cool but what about The M.G.A.C.F.S. , can you get in between the fins too?
