Reflectors would not work on leds like t5s or MH...they are basically lasers, all the light is being pointed straight down, so there is not really mouch light leakage upwards that would be reflected downwards. I may be wrong here but pretty sure this is how it works, please somebody correct me if this is not true
But the vortech style return pump would be awesome! Id be a user from day 1!
Don't point the LED towards the water. Point it up towards the reflector. Go look closely at your headlights. You can't even see the bulbs, because there is a little piece of metal blocking the light from shining forward. It points back towards the car, hits a reflector, is spread out, collimated, and shot forward. I'm not saying it would work (although I think it would, and would probably produce a lighting spread closer to a MH), but I think it is worth a shot. At a price point that would be double a normal Radion, you could put allot more LEDs on it also. Maybe have 4 triangular PCBs with identical LED clusters on it. Put them in a square configuration, so the make a pyramid to where they all face up at an angle into the square domed shaped reflector.
