840CHIP/m Digital COB RGBCCT strip light from ElisaLED integrates 840 COB chips per meter with an embedded WS2805 IC, delivering a continuous, dot-free light surface across a 10mm or 15mm PCB. Its 5-in-1 RGBCCT architecture combines Red, Green, Blue, Cool White, and Warm White channels on a single strip. Running at DC24V and 29W/m, it supports both vibrant color animations and CRI >90 tunable white output within one installed system.
Unlike standard SMD strips, COB encapsulation places all 840 chips directly onto the board, removing the visible dot pattern common to traditional addressable strips. The result is a continuous, uniform light surface — well-suited for slim-line aluminum channels with shallow profiles.
The "Digital" designation means every segment is SPI-addressable via the WS2805 protocol, enabling individual pixel control for light-chasing effects, color transitions, and dynamic animations. The RGBCCT architecture adds dedicated warm white (2700K–3200K) and cool white (5600K–6300K) chips, allowing the white output to reach CRI >90 without relying on mixed RGB to simulate white.
This combination addresses three common challenges in addressable lighting: pixelation in narrow profiles, poor white quality in RGB-only strips, and limited color temperature control in dynamic systems.

Dot-Free, High-Density Output
The COB architecture with 840 chips per metre generates uniform light even within small aluminium profiles, without hot spots evident between the chips.
5-in-1 Color Architecture
The RGBCCT design allows for full colour animation and high CRI adjustable white output in one strip, removing the need for separate lights for various lighting modes.
Individual Pixel Control
The WS2805 SPI protocol, 14 ICs per metre, enables independent control of each pixel segment and supports complicated animations, scene transitions, and circadian rhythm routines.
DC24V for Longer Runs
Running at 24V will mean less voltage loss than 12V systems. This, together with power injection every 5 meters, helps to keep brightness and signal timing constant across long deployments.
Thermal Control
The flip-chip COB architecture allows direct heat transmission to the PCB. To ensure colour stability and product lifespan, a 29W/m density Aluminium profile is suggested for heat sinking.
ElisaLED conducts systematic testing before every reel is sent.
Spectrophotometric Testing verifies colour constancy inside MacAdam Ellipse <3 SDCM across production batches, critical when numerous reels have to be matched output on a single installation.
72-Hour Ageing Test runs each strip at full brightness to test thermal stability and IC performance under prolonged load, catching early failures before shipping.
Signal Integrity Verification Using Oscilloscopes The objective is to verify clean digital data signal over the whole strip length, without flickering or data dropout.
Mechanical Durability testing include gold wire bond strength and 3M adhesive peel tests to minimise the likelihood of field failures during installation or long-term usage.
IP Rating Verification The IP65 and IP68 versions are subjected to salt spray and immersion testing to certify the integrity of silicone encapsulation for outdoor situations.
Architectural Cove Lighting
In hospitality and commercial interiors, the strip for 840CHIP/m Digital COB RGBCCT can transition from functional warm white during daytime to full-color output in the evening — all within one installed system.
Media Facades and Theme Environments
In theme parks, major retail or entertainment facilities, digital control is used for light chasing patterns that are synced with audio-visual systems. The specialised white chips allow the system to accurately represent colours while in white mode.
Smart Home & Residential Projects
The strip may also be integrated with DMX or Zigbee controllers to operate circadian rhythm programs (as well as full colour entertainment modes) for home installs.
ElisaLED offers OEM and ODM with PCB design, IC selection, housing, wiring and packaging choices. Standard lead time is 3-5 days; bespoke manufacturing lead times can vary based on project scope and will be verified upon inquiry.
If you need special CCT ranges, PCB widths or waterproof ratings that are not part of the normal choices please contact the team directly to discuss needs.
Q：What is the difference between the four digital COB LED strip options?
A:576LEDs/m Digital COB Dual Colour is addressable dual-white control; 360LEDs/m Digital COB RGB is addressable full colour effects; 784LEDs/m Digital COB RGBW is with dedicated white channel. The product is addressable RGB with tunable warm and cool white.
Q: What is the benefit of digital COB strips over traditional COB strips?
A: Digital COB strips merge dot-free COB lighting with individually addressable pixel control for smooth customisable effects with no gaps between pixels.
Q：What is the difference between Digital COB RGB, RGBW, and RGBCCT?
A: RGB is only for colour effects, RGBW adds a dedicated white channel so you can get genuine white from the strip, and RGBCCT combines RGB with adjustable warm and cool white for the ultimate in colour and white illumination in a single strip.
Q: What is the best strip for tunable white?
A: The 576LEDs/m Digital COB Dual Colour is intended for tunable white only. The product is the right solution if you need full-color capabilities and adjustable white.
Q：What should be reviewed before selecting a Digital COB LED strip?
A：Consider IC type and protocol, LED density, input voltage, color or white output requirements, control system compatibility, refresh rate, IP rating, cut interval, and the installation environment.
Q：Does this strip require a specialized controller?
A：Yes. It requires an SPI or DMX-to-SPI decoder that supports 5-channel RGBCCT digital protocols to independently manage color and color temperature channels.
