Lamps on ballast

[rpetrovski]

What happens if a 100w MH lamp is put on a 175w MH ballast? And vise versa? Does it matter the tipe of ballast?

Thanks,

Shortened bulb life with possible violent ending.

I agree.

There are a few that will interchange, but the thing you want to make sure matches is the ANSI code.

Here is a list of HID ANSI codes.

Ballast does matter unless the bulb is designed for it. A 100 watt metal halide in a 175 watt ballast will be over driven from the ballast letting in more current to the lamp. The bulb will run hotter, produce a warmer light and have a greatly reduced life expectancy. There is also an increased chance of are tube rupture. A 175 watt lamp running at 100 watts will never warm up fully and have a greatly reduced light out put with a greenish light to it. The ballast itself will usually not be bothered by it, but some electronic ballasts can.
