RE: [APD] Over driving lights
You're talking about a 2x32 electronic ballast? 2x40?
A yar or two ago, Wayne was wiring bulbs in series, if I
remember correctly, on an elctronic ballast meant for T8
32W bulbs, using half the bulbs the ballast was intended
for. The ballast was one he could pick up cheaply at Home
I believe the series wiring was the most effective. It gave
a higher voltage across the bulb assembly without allowing
more current that was useful. I don't remember if he ever
gave a wiring diagram but he experimented with hooking up
the bulbs in diff ways and measuring output, voltage,
I'd have to go back and dig up the posts to be sure.
