Although they are still sold I don't know why you would install conventional fluorescents now. They're still cheaper than LED tubes but that's the only reason I can think of. In a commercial environment the economics of LEDs win every time, both the savings on the power bill and the cost of relamping. And the LEDs don't flicker.
Who remembers the 100Hz CRT sets made by Philips and others? Wonderfully restful looking pictures but the electronics to upconvert without bad artifacts were a problem back then. If we could have done that at the dawn of TV who would have bothered with interlace. After all, the film industry showed the way by doing "up conversion" in the projector with a mutlblade shutter.
