I'd also like to see an incandescent flashlight that can put out anywhere near that much light for so little power.
Which is critically important for simulating the sun... it's no good to blast corals with tons of light if it's not in the range they can use, and we do a lot of this, unfortunately, no matter what lighting system we use.
The PAR readings on these systems are all perfectly comparable to MHs. LEDs also don't put out tons of energy in the UV spectrum, which means you don't waste power generating that and then filtering it out again which is in part where a lot of their savings comes from.
where did i say because its using less watts its not as powerful?
