Right and whats the degree of the lenses they're using? This has a HUGE effect on the intensity of the light emitted for LEDs.

What's the actual wavelengths they are putting out? Not "red" or "blue" but the actual nm?

These are the specs that actually matter and range drastically from cheap LEDs to top of the line ones.

I put in a ton of research when looking into lighting several years ago and have generally kept up with whats going on, imo.

There's no sense "saving money" on electricity if the electricity being used does not go towards putting out usable light of a decent quantity. Just because a light turns on and looks bright, doesn't mean it's good for plants...lumens have nothing to do with how a plant processes light.

Additionally, you can't make generalizations about fluorescents like "much of the energy is green" because it depends on the color temperature (k) of any specific light, which can vary pretty much across the entire spectrum (just look around the lighting section in a hardware store and you'll see this to be the case).

So while your argument for LEDs looks good in a generalized sense...it fails in actuality, which is why good (read: effective) LEDs are still ridiculously expensive for the actual amount of usable light they emit (if you haven't looked at the link I provided earlier, please do, those are literally the best LEDs I have seen discussed on any growing forum).
