Does anyone use dual arc bulbs?

If so are they supposed to change color? Mine will flicker to where the mh will be more prominent, and a few seconds later the hps will be more prominent, is this supposed to happen?

When it is firing up?

 

[greenPlantern]

It does it the whole time the lights are on

If you're using an electronic ballast, then that's likely your issue. Hortilux doesn't recommend running Dual Arc with the electronic ballasts because the ballast cannot figure out what type of bulb it is.

Magnetic ballasts are recommended for Dual Arc bulbs.
