I was in a lighting warehouse today and I came across some lighting ballasts which were for 2 X 75W, i was wondering if it would is possible to run other tubes on that for example four 40W T8 tubes or five 30W T8 tubes. The reason is that the 2 X 75W balast was going for 275.00 south african rands, which would be a lot cheaper than say five 30W ballasts @ +- 100.00 south african rand each.
