Fluorescent studies?

Does anyone know of any studies that compare various 48" fluorescent tubes for seed starting. I start lots of plants inside and usually use cheap 40 watt cool white bulbs from the Mart. I am interested to know how these compare with:

40 watt plant and aquarium tubes

40 watt 'Daylight' tubes--color temp. 6500k

A combination of regular 40 watt cool and 40 watt warm tubes

Thanks for any input

john
