MH question..whats the difference?

this may be a dumb question but hey...i'm dumb when it comes to lighting :thinking:
whats the difference between an electronic ballast and a magnetic pulse start ballast?

Efficiency, start up electrical usage. Also magnetic ones "may" have a hum to them.

thanks
so its probably worth the extra $40 bucks for the electronic ballast (single 250wt)

If its only $40, I'd pay the difference.
