Each miniature bulb is filled with inert argon gas, that turns to plasma when electricity is passed through it. The vast majority of this energy is converted into light rather than heat. These super-bulb produces 140 lumens per watt, that’s twice that of the high-end LEDs at 70 lumens per watt and 10X that of standard light bulbs in the dust at 15 lumens per watt.
