Actually, if you try to come up with a self-starting ballast that doesn't put
out a lot of heat and is small enough to fit in a typical hood, you're into
rocket science territory. The common ballast typically runs too hot to touch and
measures about 10" x 2" x 1.5". It also corrodes easily and has a tendency to
ooze polluting acids when it fails.
