So £40,000 per million-lumen hours = £0.40 per lux, no? Today that metric might look 10x better, around 4 cents per lux

- quickthrowman 2y agoLEDs can put out 200 lumens per watt, 5000 watts of that for one hour is a million-lumen hours. Assuming perfect efficiency, that would use 5 kWh of electricity, which is $0.40 total if you pay $0.08/kWh. I believe that works out to .00000004 cents per lux.
