so out of curiosity, here is the scenario you have a auto shop with 4X F96T12 fixtures and you want to save power but you dont want to remove your awesome 4X F96T12 fixture
so you replace the magnetic ballasts for electronic ballasts would that save any power what so ever? and/or you change out your 75 watt bulbs for 60 watt bulbs would that make a big difference in power draw?
or would the ballast still run them at 75 watts ?
Electronic ballast would most likely run them at something less than 75w (other than the ballast-loss savings, that's the typical way they "save" energy with ballasts)
Don't bother with 60w lamps, they still suck in cold (or even cool) weather. No flickering on electronic, but they will be dim.
You could upgrade to F96T8 as well.
Why so low power lamps in F96T12 ? Isnt there anything brighter you could put in along with ballast change ? (Are they single pin or HO ?)
F96T12 75w would always be single pin.
