Yes I agree, however the point I am trying to make is that it's so hard to select good LED lighting. To my mind any advert which does not have power used to light output some where, be it watts and lumen, or watts per lumen, and volts and amps and lumen, then it is likely rubbish.
My opinion is most of the values stated are headline figures from the LED datasheet anyway so completely meaningless. The efficacy is typically far less than this as it's near impossible to keep the die at 25°C without active cooling. If it says 100lm/W it's made up and not measured...
