I need the pulse starter for the mh400/u bulb. anyone know wat the product number is??

mine never got bight enough to be of any use. maybe whatever the pulse starter is was the prob.l

What are requirements for this bulb? I installed mine and it didn't work.

I don’t remember this particular bulb, but for metal halide bulbs there are two types, pulse start and the other type... also you have to match wattage as there is a ballast in the fixture. It’s possible that the ballast has gone bad.

The previous time I purchased these lamps you had 175w 5000 or 5500kelvin available. Do you still sell those lamps?

Not Sunlite brand. Both 175W MH bulbs are 4000K.
