LED strip light is comprised of an elongated flexible strip of printed circuit board (PCB) utilizing two or more electrically conductive traces to supply electrical power, a plurality of light-emitting diodes (LED) attached alongside the front surface of the flexible strip and electrically coupled to the conductive traces, and a length of adhesive along the back surface of the flexible strip. Modular strip lighting is extremely desirable for a number of applications, including as decorative lighting in commercial facilities where the lighting is installed for discrete display, particularly on contoured surfaces. The downsides for traditional light sources such as neon and fluorescent lamps include trouble in starting in cold weather, high risk high-voltage operation, and the presence of mercury that in turn results in an environmental hazard. Incandescent lamps generate a large amount of heat, have poor resistance to vibration, have limited lamp life, and consume considerable amounts of energy which means that most of their light energy is wasted as infrared heat energy. LED technology allows the replacement of short lamp life with longer lamp life and energy deficient light sources making use of energy efficient light sources which are long lived and cooler running. LEDs are a lot more energy efficient, more durable, and last longer than conventional light sources. The solid state design of LEDs means they are durable and robust and provides them the capability of withstanding shock, vibration, frequent power cycling and operation in abnormal cold and hot temperatures. By using of a flexible circuit board, a LED flexible strip light can create a line source with a elongated shape when electrified, and so the flexible circuit boards can be widely implemented to decoration and illumination in numerous applications. The LEDs may emit the same light or may change colors to provide an array of light options. LED strip lights typically use 5050 or 3528 RGB SMD LEDs for single-color or multi-color (RGB) illumination. These flexible LED strips can be used for architectural lighting, sign letter lighting, concealed lighting, perimeter lighting amongst many other applications. They are a cool and efficient way to decorate tables, TV rooms, bedrooms and closets. They can also serve as eye catching special effects at stores and expo booths. LED light strips are slim and discreet lighting products which may be mounted directly on most surfaces to present professional-quality lighting effects. Its adhesive back and flexible body allows it to adhere to any clean and dry surface. They typically operate on 12V/24V DC power, and can be used with a range of dimmers, switches, connectors, and other low-voltage accessories to perform a wide variety of lighting tasks such as accent lighting. And with its connectors, LED strip light is able to make sharp turns around corners. The LED strip is cuttable and linkable. It can be cut every 3 LEDs along the cutting marks, without damaging the rest strips. LED strips are packed with 5 meter per reel, each reel is a selling unit. These lights are available in ratings of IP20 (non-waterproof ), IP65 (epoxy coated), IP66 (silicone tube), and IP68 (silicone filled).
