The cartel enforced production quotas and bulb lifetimes with a system of monetary fines, backed by the power of GE’s patent portfolio. Bulbs from each producer were tested, and penalties imposed for bulbs lasting significantly shorter or longer than 1,000 hours. Phoebus continued to exert influence on the market until World War II ended its reign. The cartel is often cited as one of the first instances of planned obsolescence: designing products with an artificially shortened lifespan. A 2010 documentary, “The Light Bulb Conspiracy,” explores the history of the cartel along with some more recent instances of planned obsolescence. I wonder what the conspirators would have thought of bulbs that supposedly last 100,000 hours? Or even 7,500?
The LED keeps emitting blue and green even when dimmed, which makes it stick out in the darkness. People also perceive stroboscopic light down to 1/2000th of a second due to the persistence of vision effect, so the PWM method of dimming doesn’t work at all. In fact it is used in many flashlights to increase battery lifespan because you have to drop the duty cycle a lot before the apparent brightness starts to go down.

The goal is to not only make emergency lighting systems easier to manage but to make buildings safer. For example, sensors in emergency luminaires can not only be used to trigger an alarm but to provide the location of the hazard as well. Using machine intelligence, the system could then activate specific lights to direct building occupants away from the hazard and toward the nearest safe exit.
