Key Features of Our COB RGB 840 LED Strip

Even and streak-free

This design utilizes COB integrated packaging technology, featuring 840 densely packed RGB chips per meter. By eliminating the gaps between LEDs, it completely resolves the issues of uneven lighting and dark spots commonly found in traditional SMD lighting. The 180° wide-angle light mixing technology ensures uniform illumination, allowing the fixture to emit continuous, soft light directly without the need for additional accessories. Color transitions during dimming are smooth and natural, and the light projected onto walls is even and soft, making it an ideal choice for residential and high-end commercial lighting projects.

Soft, vibrant colors

The fixture is equipped with 840 high-density chips that support full RGB color mixing, delivering a rich and diverse range of hues. The gradient and breathing effects are smooth and natural, with no color blocking or color discrepancies. It produces pure, vibrant colors, maintaining a consistent tone throughout the fixture and providing excellent color rendering for both residential and commercial environments.

Stable and durable

This LED strip uses a highly durable FPC flexible substrate with excellent bending performance, making it ideal for installation in structures with various irregular shapes. The streamlined circuit design, combined with a highly thermally conductive substrate, ensures superior heat dissipation, minimal light decay, and a long service life. It maintains stable color brightness even during prolonged operation and remains durable and resistant to breakage even after repeated bending.

Waterproofing Applications

Multiple waterproofing options are available: the IP20 bare strip is suitable for dry indoor ceilings and cabinet interiors; the IP65 resin-coated version withstands everyday moisture and humidity in kitchens and bathrooms; and the IP67 solid-tube version offers waterproof and dustproof protection, withstanding rain splashes and ensuring reliable performance in outdoor environments such as courtyards and building exteriors. It effectively protects the circuitry from moisture damage, extending the lifespan of the light strip.

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

Avoid pulling and extruding the neon strip violently in daily use. Regularly check the tightness of connecting positions and sealing status of joints, timely handle dust and water stains on the surface to extend service life.

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.
