Steve, why don't we want to buy VHO bulbs?? Do the NO bulbs get overdriven??

Thanks

a Icecap ballast only drives bulbs at HO levels, no NO no VHO so when you use a VHO you are under driving it to HO output and a NO is overdriven to HO output. this is why everyone was commenting about 2 years ago about how NO are almost as bright as VHO's on an Icecap ballast, and even my own testing showed the price difference wasn't worth the difference in light output. especially, since we only use them for coloring the tank anyways.
