This 7.7mm, 120 LEDs/m white LED strip is single-LED cuttable: trim it at any LED, every 8.3mm, and the run ends exactly where your cabinet or channel ends. It runs on 12V or 24V DC with 120 SMD 2025 LEDs per metre, 6W/m, CRI 90, about 579 lm/m, in 2700K, 3000K, 3500K, 4000K and 6500K.
Why Choose These LED Strip Lights?
Single-LED cutting precision
A cut point between every LED lets you trim to the exact millimeter, eliminating guesswork on short custom-length runs.
7.7mm PCB width
The slim 7.7mm board fits standard aluminum channels and tight mounting slots without modification.
120 LEDs/m LED density
At 120 LEDs/m, spacing is tight enough for smooth, shadow-free illumination across shelves and display faces.
12V/24V multi-voltage input
Choose the 12V or 24V version to match a compatible constant-voltage power supply.
White-light CCT options
Available in 2700K, 3000K, 3500K, 4000K, and 6500K; choose the CCT that suits the application.
IP20 or IP67 construction
Open PCB for dry interiors; full encapsulation for damp or humid locations.
Certified & compliant
Carries CE, RoHS, CB, UKCA, PSE, and ErP marks for residential and commercial projects.
Custom lengths & options
Project quantities can be quoted with custom cut length, CCT, connectors, adhesive, and packaging.

Cutting and Installation
This single-LED cuttable design allows cuts every 8.3mm / 0.33in, 1 LED per cut. Observe polarity, use the 12V or 24V version with a matching constant-voltage power supply, and test before final mounting. Add feed points on runs over 5m to avoid visible voltage drop.
What This Strip Works With
| Power supply | Constant-voltage DC driver matching the version you order. A full 5m reel uses about 30W (12V ≈ 2.5A, 24V ≈ 1.2A), so choose a driver rated at least 40W (20% headroom) |
|---|---|
| Dimming & control | SP631E single-color dimmer (Bluetooth app + remote) or E2 Series (RF / WiFi / Zigbee smart-home control) |
| Max load per controller | 12V: SP631E 2 reels, E2 4 reels; 24V: SP631E 4 reels, E2 9 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 7.7mm; allow a little extra for the IP67 silicone coating |
Not Compatible With
- 120V AC mains — always power it through a low-voltage DC driver
- Mixing voltages — the 12V/24V versions are separate builds; order the one that matches your driver
- 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
- Cabinet interiors, shelving, wardrobes, and furniture recesses requiring precise cut lengths
- Display cases, retail fixtures, and museum vitrines where standard reel lengths would leave excess strip
- Residential and hospitality accent lighting in alcoves, toe-kicks, and 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.
