Any info on LED lights?

i am currently growing under 2 40 watt fluorescents and i was wondering about revamping my grow room. it is a closet, not too small but i am concerned about heat, so i didnt want to go the hps/hid route. i was wondering if anybody has any information on led lights, whether or not theyre good or not for growing etc.
i can not find any info on the lumens or anything for them, which is worrying me. i was thinking about the LED Spotlight Bulb from HTG, what do you guys think?

Ive seen a few grows with the LED spotlights, thay seem ok for vegging, but they can become rather expensive for a good amount of light! The led panels (225 leds i think?) are awfull for both flowering and vegging. They are only 14watts so no intensity or penetration atall! Thought about getting 125w CFL's instead? They are cheap and dont kick out much more heat? ...

They do make 28 Watt versions and up. Its also all about lumens and nm length.

there are quite a few threads popping up lately with respect to growing with leds. i personally love em. great on so many levels. the only problem i see is the few extra dollars they cost. im willing to pay a little extra for something that grows fantasic weed and keeps me off the map! happy growing dude. oh check out hydrogrow leds...i bought my 126w from there. love it. im having great results so far. check out my grow in my sig.
