Hello shillamus,
It depends on what your growing with it and how you have things set up.
cfl's are the same thing as T5 florescent
lights, except their more compact. hence the term
CFL (compact florescent light). CFL's have the
ballast in the base of the bulb, straight tube florescent lights have the ballast in the light fixture.
Weather their compact or straight tube, all florescent lights have the same issue. The usable light range is very short. The luman drop off rate goes way up beyond 2 feet from the bulb. In other words at 1 foot from the bulb your getting about 85% of the usable lumins/par to the plant foliage, at 2 feet your getting more like 60%, at 3 feet from the bulb your only getting about 25% of the lumans/par reaching the plant, at 4 your getting basically no usable light. Same goes for
led lighting.
While a 200 watt CFL will concentrate more lumans/par in one area, the coverage area is smaller. As an example four, 4 foot T5
bulbs equal 216 watts and will cover 8 sq feet of area. While a 200 watt CFL will only really cover about 4 sq feet. So the wattage is about the same but the coverage area is cut in half. You don't need 200 watts per 4 sq feet to grow lettuce. It would grow faster because of the higher light intensity. but not really worth all the extra electricity. You would be better off with the larger coverage area and growing more plants.
With that said fruiting plants take about twice as much light intensity (par/lumans) to support the fruit. While it is possible to grow fruiting plants with florescent lighting, it's not cost effective. Watt per watt your much better off using HID lighting to grow fruiting plants, especially large ones like tomatoes.
As for spectrum of florescent lighting, higher wattage doesn't mean better spectrum. It means higher light intensity (output). Unless the manufacture is selling their lights in the hydroponics industry they don't usually provide a wavelength (spectrum) chart for comparison. It's not that florescent bulbs sold in hydroponics shops are necessarily better than standard bulbs and that's why they provide the charts. Manufactures selling their florescent bulbs for household and shop lighting don't need a wavelength chart because people buying them for that reason aren't comparing wavelengths. They compere the color of the disable light by the K value. They typically range from 2400K to 6500K. The lower the K value the more of the red spectrum the light puts out, the higher the K value the more of the blue spectrum there is.
