A mod and a breeder here uses nothing but T5 and he/they gets plenty with it. T5 You have to put all different bulbs in it . Like 3000k and 5000k, 20000k, UV etc.
315 LEC are great. in that size tent it would make bricks. If you have the means then good choice. I like to build around a good light and air flow setup.
@2' wide I would go with 2 xtra sun hoods.
LED's I would use 4-6 light COB. Blurple LED's 4 of anything that does 3'-4'x3'-4'.
CFL's boxes and boxes in those 1 to 4 sockets they use for light diffusers.
T5 4' 4-light with mixed spectrums.
