ouch...this is going to hurt...turning on my brain

Isn't "Watts" (or more rather "power") just current, times voltage? Or some such.

This is correct. I had a long explanation of the differneces between rapid start, instant start and program start..but after consideration..and not wanting to bore everyone to death I think it is likely as simple as the type of bulb you expect to power with them ... T12 versus T8.

I recently discovered first hand the T8's need more power to start and to operate than the T12's

IMO.
