Overdriving lights.

[reefburnaby]

Hi,

The 18" to 24" thing...I think that is true for electromagnetic ballast. Since the operating voltage and current for those lamps are approximately the same (within 15%), the 18" will be overdriven slightly and 24" is underdriven slightly -- but the same ballast is used for both.

As for lamps exploding...unlikely. The worst it will do is burn out like a light bulb or not start at all.

If you want to overdrive a 20W, you can buy a F32T8 ballast and drive 4 outputs in to one lamp (or even two in series may be possible)....that should overdrive it by 2x.
