    led lighting differs from incandescent and compact fluorescent lighting in several ways. When designed well, led lighting can be more efficient, durable, versatile and longer lasting.

    led lighting products use light emitting diodes to produce light very efficiently. An electrical current passes through semiconductor material, which illuminates the tiny light sources we call leds. The heat produced is absorbed into a heat sink.

    led lighting is very different from other lighting sources such as incandescent bulbs and CFLs. Key differences include the following:

    Light Source: leds are the size of a fleck of pepper, and a mix of red, green, and blue leds is typically used to make white light.

    Direction: leds emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light. This feature makes leds more efficient for many uses such as recessed downlights and task lighting. With other types of lighting, the light must be reflected to the desired direction and more than half of the light may never leave the fixture.

    Heat: leds emit very little heat. In comparison, incandescent bulbs release 90% of their energy as heat and CFLs release about 80% of their energy as heat.

    leds are now being incorporated into bulbs and fixtures for general lighting applications. leds are small and provide unique design opportunities. Some led bulb solutions may look like familiar light bulbs and some may not, but can better match the performance of traditional light bulbs. Some led light fixtures may have leds built–in as a permanent light source.
