Pulse start ceramic metal halide questions.

Is anyone using pulse start metal halide or pulse start ceramic metal halide bulbs? I am looking at setting up a 100-150W CMH light and it seems that there is very little information on them. I know that the 250W + 400W CMH bulbs will burn out when used with electronic ballasts due to harmonic resonances within the bulb. I thought I remember reading somewhere that the smaller bulbs do not have this problem. Can someone confirm this for me? I am curious if I could use an electronic pulse start ballast with a 150W CMH bulb.

The 150w cmh varies by manufacturer (ge/sylvania/philips) on ballast requirements probe/pulse........but if you go for the allstart series they fire up on most

product code ... CDM145/C/U/O/4k/ED28 EA Allstart << this philips 150w CMH bulb WILL work on both probe/pulse start ballast (Uses Ansi ballast : M57,M132,M152)

Remember that even though they are Universal position, they will lose an extra 5-10% of their life being run horizontally......good luck

Thanks for the response. Just so I understand 100%, as long as the product code is correct I am all good. It doesn't matter if it is an electronic ballast or not.

If your ballast doesn't match the Ansi codes/ then I can't 100% guarantee it will work.......but if you check your electronic pulse start MH ballast and it runs at 50/60hz it should work(10,000/20,000hz NO!)....the 250w and up cmh bulbs require magnetic ballasts/ 150w cmh and below will run on most mag/ some elect ballasts ......The length of the lamp cord also comes into play with these bulbs/ finicky....good luck

You can get a 150w/250w mag ballast for very little $$$$
