Workhorse Ballasts

[Achilles]

With everything said (and I REALLY appreciate the input), it sounds like this "poor man's version" is exactly what I should use to light my refugium. Those extra features are not really needed on the refugium anyway.

Another few question though,

1. Does overdriving cut the bulb life down?
2. What is the worst case scenario from doing that.... a burnt out bulb or a burnt out house!?

Thanks!
