mh won't fire

[bnhreef]

I had problems with my MH this last spring.

The bulb was Hamilton 250w DE 14K. The bulb holders were made by PFO. What had happened was, when I seated the bulb, it took a fairly good push to get them in. In so doing, I ended up putting to much stress on the bulb contacts on each side. The wires coming out of the glass bulb are pinched into these metal contacts and I probably broke the micro spot weld (if there is one) thus causing the light to take a long time to fire. I replaced the light and this time I used a flathead screwdriver to pry the bulb holders on each side open a little and now the lights fire without any delay.

FYI I did see some tiny black arc marks in the electrode that extended onto the plaster thingymajig so there was arcing going on...check for this.

Take care.
