The 840CHIP/m COB RGB strip packs 840 flip-chip bonded LEDs into every linear meter, mounted directly onto a 10mm PCB. This density avoids the noticeable dot effect typical to SMD strips even inside profiles smaller than 15mm. The LCD splicing screen uses DC24V power supply, 14W/m power consumption, and the red (625nm), green (530nm) and blue (460nm) channels are shown smoothly and seamlessly in full colour; the IP20/IP65/IP68 is optional to meet diverse installation circumstances.
Standard SMD strips bond individual LEDs at visible intervals. In tight architectural grooves or reflective surfaces, those gaps appear as repeating bright dots and shadow lines — a problem that worsens in shallow profiles.
COB (Chip-on-Board) technology bonds chips directly onto the PCB substrate under a continuous phosphor layer, removing the gaps entirely. No external diffuser is required to achieve a smooth light line.
At 840 chips per meter, this strip operates at the high end of the COB density range. The 180-degree beam angle — compared to the typical 120-degree output of SMD strips — improves light spread and color mixing in compact spaces.

Dot-Free Linear Output
840 chips per meter leaves no visible gap between LEDs. Even with a shallow 10mm profile without a diffuser the light line is still continuous and even.
Wide angle beam
The 180 degree output spreads light more widely over surrounding surfaces than typical SMD strips, removing shadow lines and focused glare.
Stable 24V Operation
DC24V keeps electrical performance consistent across a full 5-meter run. For longer runs, powering from both ends reduces voltage variation further.
Full RGB Color Range
Red at 625nm, green at 530nm, and blue at 460nm cover a wide color gamut for saturated color effects and accurate transitions between hues.
2oz/3oz Copper PCB
The 10mm PCB uses electrolytic copper to manage heat from the dense chip layout and limit voltage drop along the strip length.
Ultra-Shallow Ceiling Coves and Wall Recesses
This strip creates a smooth continuous light line in hospitality and retail applications with recesses of less than 15mm depth where lesser density strips might still display dot patterns or shadows.
Jewelry and Commercial Display Lighting
Polished glass and metal surfaces reflect the light source directly. The 840-chip density keeps those reflections linear rather than appearing as a row of individual bright points.
Home Theater and Smart Ambient Lighting
The strip is compatible with 24V PWM, DMX512, Zigbee and Matter RGB controllers. It can manage high-frequency PWM dimming without flicker, making it a good choice for immersive home theatre and smart lighting applications.
Architectural Feature Lighting
The dot-free output and flexible 10mm PCB that bends around corners without breaking chip bonds is perfect for staircases, display shelving and hospitality interiors with narrow profile channels.
Each production batch of 840CHIP/m COB RGB goes through a structured inspection before shipment:
ElisaLED offers customised configurations, including PCB designing, LED chip selection, controller IC integration, housing, wiring, and packaging. Standard catalogue purchases ship in 3-5 days. Custom projects normally take 7-10 days.
Q: How does this strip compare to the other COB options in the range?
A：The COB range covers several configurations: 480LEDs/m for single color, 640LEDs/m for dual white, 960LEDs/m dual-row for higher brightness single color, 784LEDs/m RGBW for RGB plus a dedicated white channel, and 840LEDs/m RGBCCT for RGB combined with tunable warm and cool white. The product is the dedicated full-color option in this lineup.
Q: What is the practical advantage of COB over SMD in tight profiles?
A：COB chips sit under a continuous phosphor layer with no visible gaps between them. In profiles shallower than 15mm, this eliminates the dot and shadow pattern that SMD strips produce even with a diffuser in place.
Q: What is the difference between RGB, RGBW, and RGBCCT?
A：RGB produces color effects only. RGBW adds a separate white LED for true white output alongside color. RGBCCT combines RGB with adjustable warm and cool white for the broadest range of output in one strip.
Q: Which COB strip is best for high-brightness white output?
A：The 960LEDs/m dual-row single-color COB strip is designed for maximum uniform white output.
Q: What should be checked before choosing a COB strip?
A：LED density, required color output, input voltage, control system compatibility, IP rating, cut interval, and the physical dimensions of the installation profile are the key factors to review before ordering.
Q: Does the high chip density cause overheating?
A：COB construction transfers heat directly through the PCB substrate. Installing the strip inside an aluminum extrusion profile is recommended to maintain performance and lifespan at higher operating temperatures.
