thiis is 100 watt, there's no such a MV that is 150 watt....the next wattage to 100 for USA is 175 watt, then theres 250, and 400 and 1000.....the 700 watt was discontinued....but Iwasaki still makes them, they make one of the best lamps!
The electrodes have lost the electron emitter coating and is conducting solely by itself so it glows hot like an incandescent lamp. The early starting phase of MH lamps is also like this because their electrodes do not have the emitter coating which gives it an incandescent colour at first.
Metal halide lamp gas fill is xenon gas and a mercury gas fill is argon so the break down voltage of a metal halide lamp is much higher than mercury and emmisive material cannot aid in starting.
mine does that for a few seconds just after starting, then the electrodes go yellow/white and then stop glowing, then acts normally and warms up to full brightness. but really strange!
boy at the last half was it making noises...

What is the wattage on this lamp? I know that MV lamps below 150 W usually act different than any above that.

150 watt would be HPS...

Sorry, I meant 175, but that fact is present in HPS and MH as well.

why dont Metal Halide Lamps have Emitter on the Electrodes?

i love the way it glows green for a little. best part of mercury vapor!
