Same here. 2 fixtures with a blue and daylight light bulb in each. Once the tomato and pepper seedlings were out of here, I started 2 4' long planters of lettuce which are producing very well under one of the fixtures (the other fixture is put away).
Very cost-effective. Just keep the fluorescent lights VERY low, so the leaves of the tallest seedlings are almost touching the bulbs.
