Yesterday I went into flowering, after 3 months of having a 400w metal halide on 18/6

HPS worked as soon as I switched, and 8 hours later I unplugged, cleaned up the grow area and plugged it back in. It worked for a few hours before the 12h was done.

This morning I went to find that the HPS was flickering, when it should have been on 20 mins before.

Now it just kind of flickers.. no physical damage on the bulb, and it has only been used for less than 24 hours in total. The ballast seems fine because the metal halide works.

I tried waiting for the ballast to cool down, still nada.

Ballast is a HPS 400w... MH is a conversion bulb.

Does HPS usually burn more power than MH? Maybe my circuits are overloaded but there's enough juice for the MH to power up?

HELP!
