This decision of choosing an led for my cabinet is stressing me out,lol.the more research i do on some of the options i had in mind the more i doubt my choices.guess ill just have to pick one and jump on and dont look back.
Area 51 RW-75. How much vertical space do you have. 5w LEDs need more distance than 3w. I think LEDs mounted in reflectors need more distance than those mounted on white backboards. I have a UFO with 3w on white backboard and it can be 4" from the canopy. If you can manage 16" vertical distance, the RW-75 is your best bet, supplemented with a couple Cree 60w equivalent (9.5w actual) bulbs from Home Depot (in clamp-on reflectors). That would give you 23.5w per sq ft.
If you go with a Chinese import light (like my Blackstar UFO), you'll need more like 30w sq ft. They're not as efficient as Cree.

still gotta make a secret cab to fit in my closet. what dimensions would be best for the amount of light you mention?
The RW75 is designed for 20x20 with 12-16" vertical space in flower. If you increase the width/depth you can fill in with those Cree 9.5w/60w equiv bulbs from home depot.
If you're talking about vertical height, that's going to depend on the size of plants you grow. I do autoflowers in 2.5 gal containers in a 4' tall tent. Taking into account the height of the container, 24" tall plant, thickness of the UFO and some space above it for ventilation, that leaves me about 4-6" of distance between the canopy and UFO. Even then I usually have to LST (bend) the main cola down to maintain that distance.

If you had no budget on setting up a grow room, what would be the best, top of the line, LED lights you would buy? Buddy wants me to help him set up a veg and a flower room with all LEDs. From what ive heard californialightworks is the best but wanted to see if anyone has had better luck with anything else

Apache tech AT600 and AT200 if you are looking for more than one unit get in touch with them they will probably work with you. Good guys- professional, (work mostly in the larger industry [universities]), down to earth (willing to talk about specs and science), not there to sell you even if that is their end game they look out for your best interest.

Apache Tech AT600 is the only true 1000w replacement. Scotch above me gave the run down on the company and a link to my grow with them. More of my grows with it in my signature. It really is the best light out. Price is then only thing that keeps apaches on most people dream list. But if you are serious and want the best, call apache and they will definitely work with you guys.

400watts so it draws just over 200w.. but its under 200 bucks Delivered... these are 5watt diodes also... http://www.aliexpress.com/item/Free-Shipping-400w-mars-2-led-grow-light-strip-for-medical-plants-greenhouse-and-indoor-plants/1816886365.html

what counts is photon efficiency, see this as lumen/watt for plants.
CLW and Apache can not hold it against newer constructions (BML-Spyder)

He is right guod...that is the at120...not the at600 or 200. The new AT's use 219's.

how does the area 51 rw75 sound for a 3x2 cabinet?
It covers 20"x20" optimally, 24x24" max. You'd need some supplemental light to get about 20-25w sq. ft. (if the supplemental light is of the same efficiency as the RW. If it's not, you'd need 30'ish.).
