This is a lumens value. This is not lumens per square metre.
It is immaterial what distribution you spread the light over when comparing the light output in total in lumens.
You have confused lumen and lux. Perhaps this site will allow you to understand the difference.
http://en.wikipedia.org/wiki/Lux
Incidentally I was attempting to demonstrate the fact that that technology has moved on a great deal since the data on which you have based you argument namely 55 lumens for 3 watts.
Indeed, you can rest assured that this small scale reseller pushing these things out for as little as 25 GBP a time is selling what is a long way from ‘state of the art’.
