led set up?

I need some help from experianced growers! I am considring doing an LED light(mostly) set up. What kind of LED lights are good and what kind should I use. If I do use LED lights, should I incorporate any other lighting styles(HPS, flouresent,MH)?

I looked into this today....Ive been growing some nirvana White Rhino and some Master Kush under a 150w HPS and a 250 MH with three 42w cfls....this setup works good for veg growth so far....it seems that the LED setup could be weak....I cant seem to find any details on how many Lumens they put out.....but the plus for these seem to be the light they produce....Plants use both Blue and Red light (along with UV light for temp regulation)...with LEDS you can produce the Blue light used for C4 synthesis and Red for the Production of flowering hormones....but you need to figure out exactly how much light they put out.....let me know if this works...I would stick to the HID HPS they work well.
