We've got big lamps (DKZ)in our green screen scoops. After the phase out of incandescent lamps, these replacement lamps buzz. I've tried different brands, talked to lighting suppliers, etc., and now I have a selection of lamps that make so much noise, we can't shoot with this fixture.
Any ideas short of replacing all 5 fixtures with LEDs at 3200K? That expense is not in the budget now.
