Super Bright and Linear: COB led strip lights is new and upgrade technology that compared with traditional SMD led strip, total 2400pcs(16.4ft/5m) led chips on pcb board, high density of leds and uniform light with widely emitting angle 180° it has, the effect of COB led rope lighting looks more linear and dot-free. Safe low voltage 24vdc input (power supply not included) High Light Efficiency and CRI: 100-110 LM/W luminous efficiency and high CRI more than 92Ra are good for energy saving and eyes friendly,not only used for home decoration, it can used for Auxiliary lighting and night atmosphere creating Cuttable & Flexible: The COB led strip light is special soft and flexible that easy to bend any shape as requied, cuttable designed at every 50mm(1.96in) segment and re-joint, which suitable for various complex and different length needed applications Easy Installation & Sticky Tape: With strong self-adhesive tape, the COB led strip is easily installed on clean and dry surface without any else tools, 8mm pcb width is suitable for many different applications. Widely Use & Durable: COB led strip light adopt up to 50,000 hours lifespan led chips, with obvious advantage, and durable quality, it is widely used for kitchen, bedroom, cabinet, mirror, TV background, shelf, library, wardrobe, commercial mall, office lighting etc. COB LED strip light is upgrade from traditional SMD flexible strip, not like regular types SMD5050 or SMD2835, it only can do 120 leds/m or a little bit leds on pcb board, but COB led strip can made with 480 leds/m chips on pcb board, it looks dotless, and linear, when you install in aluminum profile or narrow channel, don't worry about darkness area, high CRI and luminous efficiency are suitable for high-end projects, to do home decoration, it has big advantage as your requirements.
