I'm after some electronic ballasts to retrofit to a number of 5ft 58 watt flourescent fittings (maybe also a couple of circular fittings).
I can get new fittings with electronic ballasts pretty cheaply (£12.95
- VAT) but I'd prefer to retrofit if I can as it will be less hassle and there will be less junk to throw away afterwards. Can anyone sugest a supplier of electronic ballasts at reasonable prices?
