I realize that this has been discussed multiple times, but I haven't found anything that directly addresses my question:
Is one 24" VHO (75watts) bulb comparable to THREE 24" T5 (24W each) bulbs? Or, is it more like 1 VHO->2 T5 or 1 VHO->1 T5?
I realize that wattage is not quite the same thing as lumens....
Basically, my math based on wattage goes something like this:
2 VHO == 150w, replace the lamps every 6-9 months costs ~$160 for three years
6 T5 == 144w, replace lamps every 12-18 months, costs ~$240 for three years
So, VHO, purely on the basis of lamp costs comes out a little cheaper (startup costs are also significantly cheaper because the cost to setup a single lamp is about the same either way: 2*x is much less than 6*x)
But, if 1 VHO == 1 T5, then the operating costs of the T5, both in electric bill and lamp costs, are much more attractive....
