Hi Ross,
We could build the fixtures with dimmable ballasts to allow full dimming on all tubes. The cost to add this per fixture is about $100. Another option is we could build the fixture with two ballasts instead of one. This would allow you to wire half the fixture separately. The cost to add this is $20 per fixture. Please let us know if you have further questions!

So I am nearing completion on my new studio and I want to have plenty of light when I need it and still be able to dim it down a notch for when I don't want it that bright. I am looking at four TechBrite 96" 4xF32T8 Industrial Strip - Miro4 Reflectors and two TechBrite 96" 6xF32T8 Industrial Strip - Miro4 Reflectors. What dimmer ballasts would I need to do this to replace in my lights. Or is step-dimming an option? Or is it even possible to wire to get only half the bulbs to light? Thanks, Ross
