       | For context: These are ultra-efficient LED light bulbs that are
       | currently exclusive to the UAE.
       | 
       | LED efficiency is non-linear with increasing power input. LEDs
       | are most efficient at lower currents. The harder an LED is
       | driven, the less marginal increase in light output.
       | 
       | The Dubai Lamp gets higher efficiency by using more LEDs and
       | driving them in the more efficient part of their operating curve.
       | More parts cost, but lower energy costs long-term.

       | Called the german ministry of environment. They weren't even
       | aware, these LEDs exist. One good option would be to move this
       | into legislation. This would be a great addition to the
       | "Okodesign-Richtlinie"
       | (https://www.umweltbundesamt.de/themen/wirtschaft-konsum/prod...)
       | regulating product design for better sustainability and
