What's the equivalent in old money i.e. Watts?


It doesn't really work like that anymore. As LED Lighting has become more efficient the lumen output has increased whilst the watts have remained the same or decreased. You need to be able to measure the lumens - effectively the amount of light output.

However, as you say in 'old money' a rough guide would probably sit these between 30 and 40 watts.
