I setup my new system and all went well until I realized I had left my 400w switchable ballast set to HPS instead of MH....

I turned off the ballast for a few minutes, switched it to MH, and turned it back on. After a few minutes the lamp starts flickering and has low intensity.

Did I fry my ballast or the bulb?

When I switch it back to HPS it goes back to full brightness....

bonehead manuever but whatever....
