Incidentally, unless my maths is failing me (and it may well be) Optolum were producing an led lamp that could produce 83.3 lumens for 3 watts almost 3 years ago; they may well have improved since then.

I've emailed both Optolum and Ultraleds to find out what their state of the art is at the moment and whose led they are using; I'll post their responses.

Hail to technology advancement. I still remembered my younger days when I had a huge argument with my lecturer. The topic was 2 valves (or max 3 valves) per piston head (petrol). I said 4 was possible and furthermore, ferrari was toying the idea of having 5!
