Sometimes i find things not on this web site or better explained (no offense I love GWE!) and i stumbled on this web page that explains LED's pretty well and also explains HID equivalency and why they say it is "equivalent to wattage" in reference to HPS or MH. Thought this would be a good place to start when looking at LED's as a grow option. I'm pretty happy with my LEC right now but i like to look at the new stuff too sometimes. here's the link if anyone is interested.
