Luxim labs recently unveiled an incredibly energy efficient light bulb that packs more luminosity than a street lamp into a pill-sized form factor. Each bulb is filled with argon gas, which turns to plasma when electricity is focused through it. The energy is driven to the bulb without electrodes. The resulting light is intensely bright and mirrors the quality of light radiated by the sun, yet is produced by one of the smallest, most energy efficient light sources we’ve seen.

A substantial portion of energy is converted into light instead of heat, which makes the bulbs highly efficient. Each super-bulb produces a stunning 140 lumens per watt, doubling the output of high-end LEDs (70 lumens per watt) and leaving standard light bulbs in the dust (15 lumens per watt). While cost and longevity have yet to be released, these brilliant bulbs represent a bright future for energy efficient lighting.
