Hi All, just a question about power consumption .Forgive me if I sound numb . Anyhow here goes . 10 x 240 v 50 watt bulbs .Or 10 x 12v 50 watt bulbs on transformers . Which one is more economical if any .I was thinking the low voltage ones would use less power but the fact they are both 50 watt bulbs is confusing me . Can anybody advise as to whether the low voltage ones would use less of my hard earned cash to run.! Many Thanks . Regards Rob.
