Dyson revealed a task light that uses their proprietary  LED bulbs that it claims last 37 years thanks to better cooling technology that adds years to the bulbs’ lives. Instead of a round heat sink encased in each bulb, the bulbs in the task light are connected to a horizontal heat-pipe technology inspired by what is used in satellites. The heat sink is made of aluminum and draws heat away from the bulbs, which the company claims keeps them at a steady 131º F and preserves the LED’s phosphorus coating, keeping them burning for much longer. With 12 hours of continual  use per day, Dyson says they should last 37 years. Called the CSYS, the task light has an interesting design that allows for moving the light 360o with both horizontal and vertical sliding arms. It features eight bulbs that provide 587 lumens per square meter of light and it has touch-sensitive dimming.
