About LED light bulbs LED light bulbs were developed in the 1960s, recent advancements have developed LED light bulbs into a bright, efficient, long lasting and purely electronic source of lighting that produces very little waste. LED’s function on a polar mechanism, the amount of light emitted is based on the shape and curvature of the housing surrounding the lens. LED bulbs are therefore measured by the radius of curvature (mm).
LED light bulbs are being used for their energy efficiency
and overall cost effectiveness, they last longer and are 5-6 times less power
consumptive that comparable incandescent bulbs.
