need help about my grow light

i recently bought a Hydrofarm FLT24 2-ft/ 4-Tube T5 Commercial System with Bulbs which puts out about 8000 lumens . is this made just for vegetation and if so what kinda light do i need fore flowering 3 plants? btw its a closet grow roughly 7ft high 6 ft wide and 3 feet deep

Get 2700K T5 bulbs for the same fixture when flowering. I suggest two more fixtures, also. Or perhaps a 400w HPS instead.

Vage,
Get a 600 hps and if you're going to use the whole space...you may need a light mover.

Now do i replace yer current light with those?

Seriously, nobody can help you at this point...with such little info. Read a book.
You said you were going to use the flouro for veg...so do that until you're ready to put them into 12/12 and then activate the HID.
