Need a light for 3x3 foot print.

High Times winner of best LED of 2016 is G8. go to dormgrow.com and read all about it. I have a 3x3 tent and the G8 -240 with flower booster is all you need.
 
I've only had them for one grow. Very happy with the results. Growing autos so the lights are on 18/6. With both lights on, temp stays a nice 75 degrees. Best part with new equipment (cleaned everything before use in tent, including rocks at bottom of pots) is my first grow was pest free. I've dealt with spider mites and fungal fucking gnats with other grows. Almost bought some ladybugs last summer, but only had 3 plants growing outside and wasn't sure what to do with 5000 of them, for $6.99.
 
This would be a biiit of extra effort on your part (well probably a decent amount of effort) but for a damn good light you could go diy. This vid shows a build specifically for 3x3 area using Cree brand cobs.

And here's a link to the kit.

as said in the video, you'd also have to get a couple things from a local hardware store, but all in all, it's gonna come out to be only a bit more expensive than an lec upfront, it uses 20% less electricity, and it puts out more light. Lec is great, and the extra work of the diy aspect is kinda daunting, but it's an option!
 
They are white, tuned by phosphorus coating like cfls or house led bulbs, so yes. They have a fuller spectrum than hids, and significantly higher photosynthetic photon per watt. I can quick go through the vid and make a shopping list for home depot/lowes to go along with the cob kit if you're interested. I'll say that it's a bit more difficult if you can't view youtube since he has a series on diy lighting.
 
I'd say in terms of raw photons and spectrum, yes. It is more expensive upfront though, and there's the time and energy spent learning to make the light and then the building process itself.
