Ultra Brightness: Compared with traditional leds strips with spaced apart and dark bright spots, the LED strips adopted COB technology(chip on board), high dense 4800 LED chips are used on the 10m flexible board(480LEDs/M) that emits continuous linear light with no black spots in between. Soft and even light, No mercury, No UV, safe to eye. The Highlights of COB: Flexible COB LED Lights DC24V, High Quality and Energy Efficient LEDs generate 11000 Lumens (110LM/ W), Brightly Light CRI(93). 180 degrees beam angle design for 50% wider lighting, multiple chips on board for uniform illumination, NO MORE worries about dark spot! Power source is not INCLUDED! DIY & Dimmable: The COB led light can be cut every 50mm/1.97in, you can cut the COB LED strip according to your own needed length, and DIY your needed shapes. Please note that once cut, you need COB Connectors to connect cut pieces. You can use dimmer to adjust brightness(Dimmer not incouded in package). Durable and Easy to Install: Real double-layer PCB board and high-quality materials made, PAUTIX COB led's lifespan is more than 65,000 hours. Self-adhesive for stronger stick on clean/dry/smooth surface. Due to adhesive, we recommend testing the light strip before fully installing it. Widely Application: PAUTIX 24V 10M COB LED strip lights are ideal for both home decoration and public places, for directly or indirectly illumination, you can install the light strip in engineering projects, vanity mirrors, kitchen cabinets, closets, bedrooms, living rooms, wine shelves, bookshelf.ect. Warm Tips: We suggest that use DC24V, 2A power supply for led strip light 10m, 12V mains can not make the strip lit. Our strip is low voltage, it is strictly forbidden to directly connect the LED light strip to 240V high voltage, which will damage the LED light strip instantly.
