Unsual ballast/lamp wattage

Post by benlucysam » Tue Apr 28, 2015 2:40 pm

I acquired today a fairly old 2 foot 20W T12 batten, it has no identifying marks as to brand, but the ballast is rated at 1 X 2 foot 20W or 1 X 3 foot 25W, never in my life heard of 3 foot 25W, the ballast Is made in England but has no brand, I would imagine the fitting is 70s early 80s, Any ideas?

Sounds like a 3 foot 30watt choke?, or a simple print mistake?

Never heard of one of those. There's a 33" 25W though!
