4 32watt 4ft fluorescent light?

32-Watt 4 ft. T8 Daylight Deluxe 6500K

Is this light good for vegging how many plants?

6500k is OK, and as many as you can comfortably fit DIRECTLY underneath.
I only say this, because the 4' fixtures are bulky for the amount of light they produce, that's why you won't see many people asking questions about them.

Are they good enough for seedling and lil plants?

Not since 2009!

I've been running my 20"x49" veg box with a 4 bulb T8 fixture for over 3yrs now, it will work.
