It does depend on the type of plant and the type of lamp, but most
plants like a specific mix of light colors. Fluorescent lamps do not have a
nice complete mix of colors, if you look at their spectrum you will see they
are bright line with lots of large holes. A little incandescent light which
has a smooth spectrum can help with many plants and allow a lower total
light with better results.

If it works for you then don't worry.

using a mix of fluorescent and incandescent light.

My 48" fixtures have never failed to produce robust transplants, rivalling
anything I've seen at the local garden store. Prob is, 48" racks have a
large footprint. Easier to fit a 24" stand in the kitchen.
