Robe colour spot 1200at (not e)


Recommended Posts

Hi There.

I've got a Robe 1200 at that lamps on and works fine for 20 mins or so, but then the lamp dims and it keeps getting dimmer and dimmer over time. A hard reset and re-strike sorts it out for a bit.

Is that a ballast issue or a PCB issue?

I'd love to hear your thoughts

It's a brand new lamp.


I was thinking it was something to do with the fixtures ability to run the lamp on a low power mode.

I'll change the Ballast. It goes super dim if left long enough. I didn't think that was possible for the lamp to maintain an arc so low!

I'll let you know.
