the problem is they are comparing LUX which tells us diddly squat. now if you can find a report that shows some actual PAR numbers that would be interesting.

Steve I'm with you on this one. How can a small LED give off enough light to sustain the amount of intense lighting. I could may be see it working on a small tank. like 10" deep. But to see have a tank 24-30" to give off that much light. Sure the light is there but to allow SPS to grow or LPS you would need lots and lots of LEDs.

LED technology has come a long way. I sell LED flashlights and they are very very bright. Perhaps they are using the "luxeon" LED 's which are 10 X as bright as a regular LED. I use one for looking into my tank at night and believe me it is bright. If you had lots of them as I would suspect they would, it would light up a pretty large area.

Hey Greg why seeing as you sell them why don't you duct tape a whole wack of them together, hang them over your tank and thell us how they work!
  Just kidding around. In all seriousness I hope it does work not only would it be a cool thing to control the white/blue ratio but also the moneythat could be saved on power and replacement of bulbs.

Snappy, we had a guy on here that was going to send me a luxton star and driver "on loan" for me to run PAR tests as he was claiming how good they were and that he was going to start producing a LED lighting system.. well in short I sent my address he said they were on the way.. 8 months laiter still nothing. I do have a PAR sensor and have tested normal LED's very disapointing PAR output. less than 1/20th of a NO actinic bulb, so going by that if a luxton is 10X more powerfull we should still only see 1/2 of the output of a NO tube, but it would take about 5 luxtons to cover the same area.. and at 20.00 a pop it wouldn't be a cheaper method of lighting.. so if anyone has a luxton and driver they could spare for a week or two I will do tests and get some comparitive figures instead of speculation.
