I recently bought an LED light. It claims - on Amazon and on the label on the box - to be a 12W LED light. The Energy Usage Classification on the very same label also claims it uses 7kWh/1000h. Something does not add up here...
- I know that they often label LED lights with the wattage of an incandescent bulb of equivalent brightness, since that's what people are used to, but I don't think incandescents ever went as low as 12W...
  
  The incandescent bulb in my oven is 4W.
  
  Nope. There was a "incandescent ligh bulb equivalent wattage" on the amazon page, which would fit the 12W, but not what I saw in light power.
- I agree... Maybe the energy usage changes ocver time? Maybe one of the light emitters dies after some number of hours?
- amazon moment
- Perhaps the second figure is “average actual use per day” or something?
  
  The "7kWh/1000h" is the official measurement by the independent lab for the energy classification. So I'd say they are closer to reality.
  Apart from that, for a supposed 12W light, it was rather on the weak side. So that 7W measured figure fits better than the manufacturers 12W label.

oh seeing that logo brings me back
