2 sets of light strips: 1 set of white light strips & 1 set of blue light strips Installation: If your screen uses an inverter, this kit replaces it to connect to the graphics card; If your screen is a high-voltage integrated power supply card, then: the card is conductive, find 12V (capacity), and disconnect from the power supply, use a multimeter to locate and connect to 12V (capacity) Disconnect the connection to the negative pole, the card has three wires: 12V, ON, GND, 12V from the inverter connects to the 12V positive pole on the high-voltage integrated power supply card, GND connects to the negative pole, ON connects to ON/OFF. In simple terms, the high-voltage power supply is disconnected, replacing the inverter, in the high-pressure front to take power. Long lifespan, designed for screen use, expected lifespan of 100,000 hours Easy to install, using double-sided tape can be adhered to the LCD track on the screen, or stuck anywhere else With newly imported lamp bulbs, better brightness, color temperature correction The new LED constant current step-up kit supports 12-30V wide voltage input 3 1 groups are free to cut 15-24 inch universal versatility Adjustable brightness Constant current kit specifications: 7cm x 2cm (length x width) Constant current kit, also known as pressure plate Light strip specifications: 535mm x 4mm x 2mm (L x B x H) Input voltage: 10V ~ 30V wide voltage + DC 12-30V This product is the screen's light strip, high brightness, cannot directly see LED particles nearby, high-density arrangement of imported bright LED chips Color: White + Blue Material: Fiberglass panels Package content: 4 x LED light strips, 1 x adjustable constant current card, 1 x 4P cable, 1 x graphics card, 1 x cable Only the above package content included, other products are not included Note: Light and different screens may cause the object's color in the picture to differ slightly from the actual item.
