COB RGB 840 LED Strip – High-Density Colour-Changing with Seamless Light
Our premium COB RGB technology delivers the ultimate combination of smooth, dot-free illumination and vibrant colour control. With an impressive 840 LEDs per metre packed into just 8mm width, this strip creates seamless colour-changing effects impossible with traditional RGB strips whilst maintaining the professional quality of COB technology.
Premium COB RGB Advantages:
-
Ultra-high LED density – 840 LEDs per metre for the smoothest colour transitions
-
Dot-free RGB illumination – seamless colour mixing without visible LED spots. (Spotting on the images is due to the camera. They're not visible in real life)
-
Ultra-compact design – just 8mm wide for discreet installation
-
Superior colour quality – smooth, even colour distribution across the entire strip
-
High efficiency – >105 lumens per watt with full RGB capability
-
Professional grade – perfect for applications where quality matters
Perfect Applications:
-
Intricate channel letters – fit LED strip in one continuous piece rather than in multiple pieces and having to connect together
-
Premium entertainment venues – bars, clubs, restaurants requiring smooth colour-changing effects
-
Architectural colour wash – building facades, coves, features needing seamless colour transitions
-
High-end retail displays – luxury brands requiring premium lighting quality
-
Creative installations – art galleries, exhibitions, events where colour precision matters
Installation Advantages:
-
Flexible installation – no intermediate connections needed for runs up to 10m (see power planning for electrical requirements)
-
Cut exactly to length – 50mm intervals for precise fitting
-
Professional adhesive – pre-applied backing bonds to clean surfaces
-
RGB control ready – compatible with all RGB controllers and 24V LED drivers
Power Planning Made Simple:
-
1 metre = 14W (high power due to premium RGB density)
-
3 metre run = 42W (typical display application)
-
Up to 5m = 70W (requires 80W+ power supply for safety margin)
-
Up to 10m = Power from both ends (160W+ total power supply capacity)
-
Longer than 10m = Requires power injection every 5m to prevent dimming

Product Supply Options
The strip is supplied in 10m reel or cut from the reel as per your requirement.
What You Receive:
- ✅ Full Reels (10m): LED strip with 100mm of wire pre-soldered at each end
- ✅ Per Metre: LED strip with adhesive backing
- ⚠️ Per Metre Note: Cut from part reels - wire connection not guaranteed
What's Not Included:
- ❌ Power supply - requires separate 24V power supply
- ❌ RGB controller - requires RGB controller for colour control and effects
- ❌ Connectors - optional LED strip connectors for wire-free connections
- ❌ Mounting profile - aluminium profiles available separately for professional installations
Additional Services:
🔧 Bespoke Service: We can supply cut-to-length sections with pre-soldered cables - just ask!
Important Notes:
- Full reels always include wire connections for immediate use
- Per-metre cuts may require wire attachment (simple solder job or use connectors)
- Continuous lengths up to 10m can be supplied as one piece when ordering multiple metres
- Professional installation recommended for commercial applications
- RGB Controller Required: Unlike single-colour strips, RGB strips need a controller for colour changes
Professional RGB Control
RGB LED strips require controllers for colour changing and effects. Choose from simple manual controllers to advanced systems with smartphone apps, sound activation, and integration with professional lighting systems.
Basic RGB Controllers: RGB controllers - manual colour selection and basic effects
Advanced Controllers: DMX, smartphone app control, sound-to-light, programmable effects
Professional Systems: Compatible with DMX, DALI control protocols for commercial installations
Smart Home Integration: Works with RGB-compatible home automation systems
