I can't find anything to suggest that lumens are any different for LEDs. Wiki gives a generic LED a rating of 100 lumens per watt. So a 3W LED would produce 300 lumens. A 60W incendecent gives 660 lumens on their chart. They were doing a cost comparison and listed a 9W LED. I would say that Dr. LED is wrong in their figures. Maybe the name should be Miss LED.
