need help with light!

whats a good led for around 4sqft? i know nothing about led but trying to learn

do you have any exhaust before we go further?

im doing a cfl grow now. was considering led but cant research if i dont know good from bad yet

Their are some great panels for your area but it depends on the situation IMO....

if you have no exhaust at all you need to stay low wattage to deal with the temps even with led that's why I ask...

I can give you some recommendations if you tell me you exhaust situation and your room height...

2x2x3 box. can be built higher. 6 inch exhaust fan with passive intake

Even at four feet of height you wanna stay away from all secondary lens panels due to focusing issues so :

http://plantphotonics.com/our_lights.html 70 w or 140w will work very well

if you can build your cab above five feet and can keep at least ten inches away:

http://www.californialightworks.com/Products_SolarFlare.htm 200w(165w) will do well, still think bloom booster is the way to go with spectral output === but i've seen full cycle do well .....so your choice...

http://www.bsled.com/led-grow-light/h160d-210w.html 140w or 210w more watts bigger buds===that never changes, way cheaper option than others

http://shop.area51lighting.com/9-a51-90.html same deal/ lifetime warranty!!.....coming out with new panels very soon with better ppf/w soon ......

happy shopping ...........and their are many more options but these have shown good results

thanks for your help man
