Anyone seen an SST 50 Flood to throw light yet?

Like everybody else I'm trying to find an all purpose flood to throw light. From what I've read the R2 is better then the R5 behind an aspheric because of it's smaller size. I almost bought the Wolf Eyes Night Hunter R2 HO but apparently the light won't destroy my TK11, it only throws marginally better. I have seen the SST 90 behind an aspheric and looks good to me but have yet to see a zoomable 50 or 90. I know heat would be a problem being stuck behind that lens but one would think by now it would be solved.... I mean we can put a man on the moon but not safely put an SST 50/90 behind an aspheric??? I think it would eventually kill the flashlight industry if one were to make the perfect light like this cause nobody would need any other light and we would only upgrade every 10 years. Just find it odd that million dollar companies can't overcome some heat and rings in the beam pattern...
