the fulham is only available online ... it's an industrial ballast that some retailers order and resell.
talk to Greg at www.reefgeek.com
... he has them for $36 last I ordered one.
The fulham is a true electronic (not a hybrid), so it is very light and very efficient in terms of energy usage and light output. I believe the 2x59 ballast from lowes is a hybrid, which is efficient in terms of light output, but not energy usage ... both are a LOT more efficent then magnetic ballasts in both energy usage and light output
You could use a magnetic ballast to run a PC
, but they're not really designed for it, and you won't get as much light as you would from a electronic ... besides, magnetic ballasts aren't that much cheaper, plus they are harder to wire and make a lot of noise.
best routes would be:
1) buying Two 2x59 electronic ballasts from lowes like Logan suggested - net cost is $48 - each bulb would need it's own ballast - this would give you the ability to have sunrise, noon and sunset lighting.
2) buying One Fulham 7 from online - net cost is $36
of course, you have to add shipping and/or taxes
