Are LEDs the wave of the future..??

I guess we'll see once there is more testing done on them. If PFO is releasing information on their progress already, it suggests to me it has commercial viability already.

And even if for now it is just for shallower tanks, that could make a big difference for fish stores and frag grow-out tanks to save on electricity and bulb replacement cost.

Obviously this is assuming that there is some economies of scale as the technology goes from only early adopters to maintstream folk.

Just sorta in answer to the question about lux further back, the thing is lux is really just a measure of intensity but not a measure of PAR (photosynthetically active radiation). What would be really interesting to see would be the PAR outputs of that unit. e.g., a halogen bulb is really bright but wouldn't be very useful over a reef tank due to the spectrum. (You don't even see halogen's used as plant grow lights.) So I think the long-term viability of the unit will depend on what ppfd/PAR comes out of it. Anyhow that's what I think would be interesting to see.
