need MH and PC ballasts

[segraves1]

checked on the WH5 output and it is indeed 128W

COULD I:

run 2, 65W PCs (130W total) off of the higher output capacity WH7 (rated at 220W) or would that cause problems?

as I understand Fluorescent Ballasts, they can power anything UP TO their max rating.

Actually according to Fulham a WH5 will drive a pair of 65w... but a WH7 will drive them as well without doing any harm.

Here's a great reference page I wrote up for the bulb types and #'s for all of Fulham's fluorescent ballasts.
