On L530E bulb it show's energy usage and energy saving. The energy saving being much higher than usage but I can't find any explanation for these figures I can only try to make sense of it by assuming usage is the bulbs usage and energy saving is showing the energy that would be used by a 60 watt bulb? If this is the case it's slightly misleading as it's showing what a 60 watt bulb would be using if it was switched on for the full 24 hours a day rather than the equivalent of what the smart bulb is using while in operation. Not that it matters I just want to figure out what the app is trying to show me with these figures!!!
