Light question

[tzhanks]

I just got my new metal halide and when I plug it in the light does not turn on. How do i know if the light bulb or the ballast is the problem?

[alton]

Borrow a lamp, what is the wattage?

Is the bAllast magnetic ? If so u should here a hum

[tzhanks]

It is a 150w and the ballast is a External 150W Electronic HQI Metal Halide Ballast. Even though the ballast is not magnetic should it hum?

Also note that when you turn it on it can take some time to warm up and give off light. My first MH I thought was damaged because I expected it to come on right away like a normal light, MH do not work this way.

Its also very bad to constantly flip the on/off switch over and over, you can damage a MH this way.

Put it on off mode for 20-30min and then turn back on and wait and see what happens. I can take 10min or longer for full intensity.

I have left it plugged in for 6 min and still no light so I unplugged it. Should I wait 30 min and plug it in longer?

If it is new take it back to where you bought it.

You need to leave it on for at least 30 minutes. If they fail to light, they cycle.

Make sure the bulb is well seated.

Also check the fuse on the ballast.

Shouldn't hum. Also the ballast should be slightly warm after 30 minutes. Warm is good, hot is bad.
