Key Features of Our COB RGBCW 840 LED Strip

No spots

Featuring a high-density COB flip-chip design with 840 LEDs per meter, the light source is densely packed to produce a seamless, uniform light output with no visible LED dots or dark spots. The 180° wide-angle diffusion ensures even light distribution and smooth, seamless transitions, making it ideal for both residential and commercial linear lighting applications.

Bright in both color and white

The COB RGBCW 840 LED strip features RGBCW 5-in-1 LED chips, capable of producing over 16 million vibrant colors, complemented by cool white and warm white light. With a color temperature range of 2700K to 6500K and stepless dimming, it delivers a high color rendering index, perfectly replicating natural light. A single strip can serve as both primary lighting for daily use and decorative ambient lighting.

High color rendering

High color rendering with a Color Rendering Index (CRI) of 90 or higher, accurately reproducing the colors of objects and skin tones without color distortion. Designed with eye health in mind, it meets the high-standard lighting requirements for commercial displays and home use.

Stable and durable

Featuring high-quality FPC circuit boards and COB integrated packaging, these lights offer excellent heat dissipation. Operating at a low voltage of 24V, they generate minimal heat, exhibit minimal light decay, and have a service life of up to 50,000 hours. They are resistant to bending and breakage, ensuring stable and durable performance over the long term.

Daily Installation Notes

Pre-installation Preparation

Clean the installation surface to keep it flat and dry, confirm the matching power supply voltage is consistent with the product rated voltage, and check whether the strip surface has damage or circuit abnormality in advance.

Wiring & Laying Rules

Keep positive and negative poles in correct connection status, avoid wrong line connection causing circuit failure. When laying ultra long distance strips, adopt double end power supply mode to guarantee uniform brightness of the whole light strip.

Daily Maintenance Tips

Never bend or twist COB light strips; 12V/24V models require a dedicated power supply. We recommend installing them in aluminum channels, ensuring adequate heat dissipation and keeping them away from high temperatures; IP20 models must not come into contact with water or condensation.

Phenomenon	causes	solution
whole strip not working	1、positive(+) and negative (-)Connection wrong. 2, input voltage too low. 3, Power supply failure .	(1)checkthe+and -connection right between power supply and led strip. (2) check the power supply output voltis same with strip working volt.
whole strip with slight brightness and few sections bright	1、positive(+) and negative (-)short circuit of input wire, the resistor and chip led be burnt by surge. 2, leds will be failed by the power supply leakage or strip components touch the metal object around .	(1)please do not connect the wire with electricity, and make sure strip without any short circuit before power on. (2) check the power, strip and metal object allisolated
led strip Color difference	1, something fall on the surface of LED.	(1)check the LED surface if anything fall on, like oil, dust,putty powder, then clean it.(this issue always happen in the project, suggest toinstall the led strip when decoration done.)
one section orfew sections failureor color missing	1, the pad of components crack by the wrong fold or people step on the led strip . 2, the chip of led burnt out.	(1)cut the failed section and replace with new section. (2)the led burnt out by ESD orthe strip surface-to-surface touch each other or strip surface touch metal cause the short circuit.
the brightess is big difference between the front and the end	1, the strip length is too long make voltage drop.	(1)suggest to power strip on both sides when constant volt strip length>7meters and constant current strip length>15meters.
strip fall off from the object	1、the object with paint, dust and silicone will make the tape sticky weak	(1)suggest to clean the surface of object before stick the strip.
led strip white colorturn blue color	1, the fluorescent glue of ledare corroded by something.	(1)if you need to use something like glue, tube, plastic to fix the strip,...please use the netural type, do not use acid type or something with sulfur.
