very true......however i dont like the idea of fronting major omounts of money for what at the moment amounts to an experiment.......i REALLY do want to see more reports of how plants grow long term for "home growers" and not someone in a lab and see weither it becomes worth it to switch to LEDs. given my grow setup at the moment LEDs would have to last significantly longer than 8 years.......im currently only replacing maybe 4 fixtures a year and going through 2-$20 cases of lights for around 24 linear feet of shelf space(mix of 12 and 18 inch wide) so for an initial out put of around $160 for fixtures, ~$60 for bulbs and an annual cost of $80 for replacing bulbs and burned out fixtures and given my current setup doesnt affect my electric bill much..........its going to take a SIGNIFICANT amount of money to change to LED to cover the 24 feet of shelves so the fixtures, LED's themselves would need to last an aweful long time to make sence to me.However, given the increase in efficiency and longer life (vs fluor lamp & ballast), LEDs should command a premium.
i WOULD like to try LEDs for growing Heli's though due to the lack of heat they put off........that sounds like an interesting possibility.....
They need to re-do the test using those bright WHITE LEDs and move them much closer. Also, they should use regular florescent tubes instead of aquarium tubes or specialty tubes.

Here is a link to a page dedicated to experimenting with different LED grow lights:
Nothing scientific, but does show that LED lights can be used successfully- the plant chosen for the experiments being tomatos, which were grown on to produce fruit.
I agree about the insane initial investment required. They likely won't ever become an alternative for those using shop light setups, but as the technology improves they should become a viable replacement for HID lighting.
