generally you want 10,000 lumens per sq ft to mimic outdoor sunlight.
Minimum you need 2,000 lumens per sq ft to grow.

For a 1 sqft area yes it's "enough" but not optimal, probably want to add another bulb during flower for 1sqft though.

My cab is slightly over 1sqft (16" x 12") and I'm running 115w with 8k lumens @ (3x 2.7k & 2x 6.5k ) so sounds about right to me :) As long as you're only growing in a 1 sqft space :P Remember to keep the light max 3 " from your tops, really unless they touch your bulbs they won't ever burn.

This was taken a few days ago, just before flipping into 12/12. They are three bagseed, so most likely 1 or 2 will get culled in the next few days when I can tell their sex :)
