+1 it's a safety feature to prevent your bulbs from blowing out. My controller won't let my MH fire back up for 15 whenever my lights would flicker and lose power for half a sec. No need to worry, just don't go plugging and unplugging the thing all day. It's not good for it. Also new bulbs need a good few hours of continue run time for it to burn in and work properly.

It's normal as others have stated.
