An LED lamp or LED light bulb is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and can be significantly more efficient than most fluorescent lamps. The most efficient commercially available LED lamps have efficiencies of 200 lumens per watt (Lm/W). Commercial LED lamps have a lifespan many times longer than incandescent lamps.
Linear lighting is defined as a linear shape luminaire (opposed to square or round). These luminaires have long optics to distribute the light over a more narrow area than with traditional lighting. Usually, these lights are long in length and are installed as either suspended from a ceiling, surface mounted to a wall or ceiling, or recessed into a wall or ceiling.
