Lighting suggestions

[mike31154]

Have you considered tossing the PCs entirely and trying to modify the fixture with retro T5HO lamps? If that's possible, it might be worth giving it a try. Much more choice in bulb temperature/colour and with indivdual ballasts/reflectors the light output increase would be substantial. You might even be able to keep the MHs turned on for a shorter period and save a few kilowatts.
