I played around with this alot in the winter using "grow" lights...some 6500k led corn bulbs as well as some CFLs. Since I didnt get a chance to really use one or the other on its own I cant tell you what was better but they would all work just fine. I will list some of the stuff I bought and most of it is very inexpensive on ebay ect can just do a quick search to look at it.
5m 300 Led Grow strip lights (12v 5A power adapter required) $10 + adapter
45w grow panel light $25-30
Various LED grow bulbs 28w (28led) $3 200led (34w) $5 and a couple 126led bulbs (100w) $20 each)
165 led (5730) and 200 led (2835) corn bulbs 6000-6500k+ which gives of more of a blueish light $3-$4 a piece
Couple 4 and 5 way corn bulb adapters
CFL 5500k and 6500k bulbs 3 pack $10 (local store)
Hanging pendant light bulb holders $3 each
The $ amount is in CDN and most of it I bought from Ebay which I found to be the cheapest place for the stuff I wanted....On anything you buy just take some time and do your research if you have the time to do so.
I got all my stuff over a 5-6 month period and some I asked my wife to buy me for x-mas ect...Since space is an issue you could always go the corn bulb route with an adapter and it really gives the best bang for your buck in any space regardless. As far as grow lights go the strip lights for me were the most cost effective way to go..sadly I didnt figure this out until after I had all my other stuff. You can even make your own grow light just using Red and blue strip you buy on there own as well. If in a large grow box you can just set up a 3/4 to 1 red to blue ratio like most strips and grow light s are set up OR you can cut them up and make the strip however you want.
Good luck finding the best set up that works for you.
