I recently switched back to MH and am running the purple select a watt 250w-400W lumatek ballasts. With a sunlight supply 3x250W DE Maristar fixture.

So far the results have been great compared to LED after two months and would like to mount the fixture.

Am I am able to mount these Ballasts on their side or upside down (directly to ceiling). Or do they have to be mounted right side up on a flat surface?

Thank you!
