It would be great if consumer electronics products had expected lifetime ratings on the front. People would naturally take issue with products with significantly below median lifetime, and also if their own products didn't live up to the lifetime.
It would also make sense to phrase other quantities on product packaging in the way they're experienced by the consumer: instead of emphasising the wattage of a bulb, if you showed the lumens/$, more efficient bulbs would naturally win out. Instead, LED bulbs have fake wattage numbers to show the equivalent wattage incandescent lighting that would be needed to match the LED.
