I remember reading in a post on here...not sure which one and too lazy to look unless we need it
...that there was a MH
bulb that would fire on a mercury vapor (read: cheap) ballast. Can someone explain the difference between probe start and pulse start?
On another subject, I have posted about the 2x32 & 4x32 electronic instant start ballasts for PC
's until I guess everyone is sick of hearing about it. I read that PC
bulbs will light on a rapid start and even a magnetic ballast too. Anybody have any experience with this? Don't the magnetic ballasts light the bulbs at a lower frequency which increases flicker and reduces bulb life? Or am I confusing this with the Icecap sales pitch?
Another thing I have noticed about MH
ballasts is that many of them are capable of operating on different voltages. A pile of them at a Shaw Industries plant that I was at this weekend were stamped 120/208/240/277 for voltage. I have seen others that were like this too. The point? If there is an industrial complex in your area, and you know someone there, you might ask if they are replacing any of their MH
lights...might get the old ones really cheap. Lots of the places around here are changing to fluorescent lighting. I'm looking
