I was just talking to Ken from Wavien about their RLT LEDs. When asked about XP-G2 RLT LEDs he said they were not a standard product so I would have to supply the LED on a 20mm board, and that he would charge 80 dollars for the mounting service. 
At that price I would just buy one of their premade SST-90s.
Just thought I would post this for anyone else intrigued by them.
i am very… how much was an sst-90, and do they have any other LEDs available?
SST-90 and others are available on their site and the cost is $99 for the SST-90
a little too rich for my blood. nice to know they are available though i guess

$69
I wonder if I get a parabolic or semi spherical reflector and put it upside down over the led would yield the same result… What you all think?
Does wavien just make really well heatsinked leds?
No, they have their own "optics" of some sort that they mount on the LED which focuses more of the light forward.
Ill wait for the $11 UltraFire version :bigsmile:
I’d probably be willing to drop $30 on an xml version of it if it ever drops down to that.
Is that heatsink necessary or are they just being over dramatic with it?
I looked at their page the first day I saw the deft-x, and wondered how that could fit in a flashlight (especially the heatsink).
I thought about asking if the collar is available separately, but didn’t bother…
I would imagine there is a pretty tight tolerance in mounting the collar to make it efficient. Could be wrong though
I was looking at them too,really cost prohibitive and might be worth saving for if you want a killer aspheric build.I am skeptical about the 80% increase in brightness,but that has to be on a focused aspheric lens.I found a few you tube videos about this technology and I think the transition to flashlight would be a trial and error project.Too bad the SBT-70 is so dang inefficent,it would probably be a killer flashlight.
absolutely, but w/ instant feedback from a light meter, i’d guess you could find that sweet spot
alternatively, the complete unit could be mounted in something like the fatmax spotlight…
I can’t figure out why the their xm-l page says 8”x6”x6”. Judging by the size of the die/star, it is nowhere near that large.
Yep I saw it,pricey and inefficent,might be nice with MTG2 to focus all those lumens but the die behind anaspheric is straight up ugly-looks like a stop sign with bullet holes in it,lol.
some of the guys on mtbr tried making little mini parabolic collars for XM-L LEDs to do the same thing with aspherics. It seemed to make a bit of difference in output, but no where near worth the hassle. This RLT mumbojumbo seems to be the same deal. I wonder how their way of collecting the “high angle” light is any better than the reflectors and TIRs we use?
If the DEFT-X is any indication, it obviously has some benefit…
look at the deft-x… it obviously works
I don’t doubt that it works, I just want to know why it works 
It looks like some kind of inverted parabolic reflector feeding an aspheric, which shouldn’t be too hard for someone to replicate with an appropriate reflector that matches the focal length of the aspheric. Obviously there’s probably some optical tuning of the reflector used in the RLT thing for maximum efficiency, but you should be able to get most of the gains with a simpler reflector.
It would be interesting to see someone try
it works because light that couldn’t normally reach the aspheric is directed back at the led, further exciting the phosphor (increasing output)
actually I think they’re spherical reflectors. there is a thread on cpf from a year ago where someone experimented with making a small collar from aluminum - with fair results, imho.
last night I found myself wondering - are christmas ornaments mirrored on the inside, too? :Sp
