Setting up a veg room. looking for some input

[Taint85]

I am going to set up a 5x5 veg room. I am limited on height only have about 4 feet to work with. For that reason I am going to use a 4 foot 4 bulb t5 fixture. My question is what type of bulbs do guys might recommend. I have done some research but I’m having a hard time finding in depth instruction. Thanks in advance.

I’m a new grower and I only have 2 light bulbs in my tent and my plant is growing great it didn’t stretch a little so keep the lights 12-15 inches away maybe tile the first full week is done then gradually move the lights up

This is my set up
