an ok light size?

hey everyone im growing well im new im growing in my closet which is only about 2-3 feet in width now Im only growing 2 plants so I heard that you need about 3000k per 1 square foot so I got this huge bulb its obv a fluorescent its 6500k and 250 watts its huge lol so only have around 3 sqaure feet I got 6500k let me know thanks

look at the watts per foot, as the lumen output on those is sometimes misleadingwith floros you want 50 actual watts per foot so you also have tosee if that bulb is 250 actual watts or 250 eq. watts, i have one of those big ass bulbs in my livingroom, its like 56 actual watts and 300 eq.

so its a good bulb?
