With 280 LEDs per metre on a 8mm board, this high-density white LED strip gives a smooth line with little visible LED spacing, even in shallow channels. It runs on 24V DC with 280 SMD 2025 LEDs per metre, 12.8W/m, CRI 90, about 1,664 lm/m, in 2700K, 3000K, 3500K, 4000K and 6500K. Cut points fall every 25mm.
Why Choose These LED Strip Lights?
280 LEDs/m high-density LED layout
The 280 LEDs/m pitch eliminates visible bright spots and delivers continuous, uniform illumination across the beam path.
SMD 2025 chip technology
SMD 2025 LEDs maintain consistent colour and output at high packing density.
8mm PCB width
The 8mm board is compatible with standard extrusion profiles and surface-mount channels.
24V constant-voltage input
Constant-voltage 24V input works with standard LED drivers and dimming systems.
CRI 90 colour rendering
High CRI ensures accurate colour rendering for retail merchandise, artwork, and hospitality environments.
IP20 or IP67 options
Open or encapsulated construction available for dry, damp, and wet locations.
Certified & compliant
CE, RoHS, CB, UKCA, PSE, and ErP compliance marks for professional installations.
Custom supply available
Project quantities quoted with custom CCT, length, power, connectors, and packaging.

Cutting and Installation
Cut only at marked cut points (25mm / 0.98in, 7 LEDs per cut). High-density strips generate more heat per metre — mount on an aluminum channel or heatsink for best thermal management and long-term reliability. Size the power supply with at least 20% reserve capacity.
What This Strip Works With
| Power supply | 24V DC constant-voltage driver. A full 5m reel uses about 64W (2.7A), so choose a driver rated at least 80W (20% headroom) |
|---|---|
| Dimming & control | SP631E single-color dimmer (Bluetooth app + remote) or E2 Series (RF / WiFi / Zigbee smart-home control) |
| Max load per controller | 24V: SP631E 2 reels, E2 4 reels. Wire each reel back to the controller separately rather than chaining reels end to end |
| Wall dimmers | A 120V wall dimmer only works through a dimmable driver that matches it (TRIAC/ELV or 0–10V); it cannot dim the strip directly |
| Mounting | Aluminum channel with an inner width of at least 8mm; allow a little extra for the IP67 silicone coating |
Not Compatible With
- 120V AC mains — always power it through a low-voltage DC driver
- 12V drivers — a 24V strip on 12V will run very dim
- RGB, RGBW and addressable (SPI) controllers — this is a 2-wire single-color strip and needs a single-color dimmer
- Outdoor or damp locations in the IP20 version — choose the IP67 option, and use a driver rated for the location
Recommended Applications
- High-end retail displays, jewellery showcases, and merchandise lighting requiring shadow-free uniformity
- Museum and gallery picture lighting where visible LED spacing is unacceptable
- Hospitality back-bar illumination, feature walls, and architectural cove details
Purchase Options and Customization
Select the required color temperature or color mode and the appropriate IP20 non-waterproof or IP67 waterproof construction. The standard length is 5m Reel / 16.4ft. Custom size, CCT, power, adhesive backing, cable, connector, packaging, and project quantities can be quoted separately.
