To begin with is was to replace incandescent lamps as indicator. But nowadays it is used for myriads of uses from indicator to lamps fixture for your House there are also specialty LEDS like ultraviolet and what not

Home LED lighting is a cut above the rest when it comes to energy efficiency. As compared to incandescent lighting, LED lighting wins hands down where energy consumption is concerned. For every 60,000 hours of usage, incandescent lighting uses approximately 3,600 kWh of electricity where LED lighting uses 120 kWh. Bottom line: energy efficiency equals a significant cost savings. LED lighting gives off directional light. Therefore, it is useful as a source of light for reading or spotlighting in the home. Its powerful light output also makes it great for outdoor floodlighting and path illumination. LED bulbs are now available that can replace most halogen or fluorescent light bulbs used in the home.

Although LED lighting may not be useful for all home lighting needs, replacing a few bulbs with LED bulbs would have a noticeable affect in the amount of electricity used.

LED light displays are already used in signs and videos in many indoor and outdoor sporting events and concerts. LED video displays and signs are often preferred because of their higher brightness, which is critical when people are viewing a sign or video from a long distance. Added advantages of LED video displays are their capacity to incorporate curves and 3-D design. This makes LED video displays technologically superior to currently available large screen displays. Research and developers in the consumer electronics space are eager to take advantage of this overwhelmingly useful technology in future products.

Other uses for LED lighting include LED flashlights and key chains, automobile taillights and interior lights, and LED based projection televisions. LED lighting is also being used in the military for LED flashlights that work with night-vision goggles, UV-LED canteen water treatment devices and the sterilization of surgical equipment.

ANSWER NOT USED IN A HOME are kidding ? all my lighting inside and out is all LEDS never shut them off what for? saving is in the 98%

replaced 3 60 watts lamps with 3 90 watts LED using total 10 watts
