DIY Dimmable Ballasts

[mkrupp]

I've checked the other threads and couldn't find anything that directly answers this:

I have a 45" tank and want to install dimmable T5 lighting. 48" tubes are too long.

The only dimmable ballast available here (Canada) seems to be the 54 watt which is intended, as I understand, for 48" bulbs.

The question: Could I connect 2 - 24" bulbs together and power them with the 54 watt dimmable ballast? If so, would I wire them in series or parallel?

Thanks for any insight.

This is not possible.
