This 4mm, 240 LEDs/m white LED strip runs on 24V for longer runs with less voltage drop than 12V, with high CRI 95 light that shows wood, food and fabric in natural color. It uses SMD 2025 LEDs at 9.2W/m (about 930 lm/m), in 2700K, 3000K, 3500K, 4000K and 6500K. Cut points fall every 25mm.
Why Choose These LED Strip Lights?
24V for longer runs
24V DC halves the current at the same wattage, reducing resistive losses and allowing longer uninterrupted runs before voltage drop becomes visible.
4mm PCB width
The 4mm board fits standard aluminum extrusion channels and surface-mount profiles.
240 LEDs/m LED density
240 LEDs/m provides smooth, even white-light output for general and accent lighting.
SMD 2025 chip technology
SMD 2025 LEDs deliver consistent white output and long operating life at 24V.
White-light CCT selection
Available in 2700K, 3000K, 3500K, 4000K, and 6500K.
IP20 or IP67 options
Open PCB for dry locations; encapsulated construction for damp and outdoor-adjacent environments.
Certified & compliant
CE, RoHS, CB, UKCA, PSE, and ErP marks for residential and commercial projects.
Custom project supply
Custom CCT, length, power, connector, adhesive, and packaging for project quantities.

Cutting and Installation
Cut every 25mm (0.98in) at the marked cut points. Use a 24V constant-voltage driver with at least 20% reserve capacity. 24V strips support longer runs — still add feed points on very long continuous runs to maintain consistent brightness.
What This Strip Works With
| Power supply | 24V DC constant-voltage driver. A full 5m reel uses about 46W (1.9A), so choose a driver rated at least 60W (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 3 reels, E2 6 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 4mm; 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
- Commercial cove lighting, perimeter lighting, and long-run architectural linear installations
- Retail environments, hotel corridors, and office spaces where minimal voltage drop over distance is required
- Residential and hospitality cabinet, display, and accent lighting on 24V DC systems
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.
