Convert failed HPS Ballast?
I have a Sun System 10 600W HPS ballast that just failed. It was five years old and out of warranty (practically by the day!) so I opted to do a direct replace. New ballast is on its way.
Is it possible (and at all economical or a good idea) to try to convert the failed HPS ballast to a Metal Halide ballast? Or to something that will run a CMH bulb? Do I have any options like this, or am I stuck with a hunk of throwaway ballast?
Thanks in advance for any opinions!
