Incandescent lamps are the most inefficient due to the fact that they rely on the heating of a filament to produce light, which wastes a lot of energy as heat. Fluorescent, metal halide, and LED lamps are all more efficient options. Of these, LED lamps are generally the most efficient choice as they use the least amount of energy and have the longest lifespan.
