22mm Magnetic Track Tunable White Series
Linear · Grille · Spot · Wallwasher — Four Fixture Types, One Track, Every Shade of White from 2700K to 6500K Per Fixture
What Is the 22mm Tunable White Magnetic Track Series?
The 22mm Magnetic Track Tunable White Series is a 48V DC low-voltage magnetic track system that combines the flexibility of magnetic fixture positioning with per-fixture CCT tunable white control. The 22mm track width supports a broader fixture range than narrower track systems — including linear bar modules, anti-glare grille spotlights, standard spotlights, and asymmetric wallwasher heads — all on the same track, all individually CCT-adjustable.
22mm Track vs. 5mm Ultra-Slim Track
Two widths, different strengths — choose the track system that matches your fixture needs and aesthetic priorities.
🔵 22mm Magnetic Track — This System
- 22mm wide — slim but visible ceiling detail
- Four fixture types: Linear, Grille, Spot, Wallwasher
- CCT tunable white — 2700K to 6500K per fixture
- Higher wattage capacity — up to 30W fixtures
- Recessed or surface mount options
- Best for spaces needing fixture variety on one track
- Linear bar and wallwasher not available in 5mm system
- Grille spotlight for UGR <19 office compliance
⬜ 5mm Ultra-Slim Track
- 5mm wide — hairline, virtually invisible when recessed
- Spotlight and downlight fixture types only
- Fixed CCT per fixture (or CCT tunable — separate model)
- Lower wattage capacity — up to 15W fixtures
- Recessed only (ultra-slim profile)
- Best for spaces where ceiling appearance is paramount
- The invisible track — only fixtures are visible
- Lower fixture variety trade-off for minimal visual footprint
Four Fixture Types
All four fixture types connect to the same 22mm magnetic track — mix and match freely on any run.
Linear Bar
Ambient · Fill LightElongated linear LED module producing a short continuous line of diffused light. Creates architectural linear detail on the ceiling plane and provides soft ambient fill below the track. Available in 200mm and 300mm lengths.
Grille Spotlight
Anti-Glare · UGR <19Square or rectangular spotlight with anti-glare grille diffuser. Eliminates direct source visibility while maintaining focused directional output. UGR <19 compliance for offices, co-working spaces, and hospitality environments.
Spotlight (Round)
Accent · DisplayStandard round directional spotlight on adjustable head — tilts and rotates for precise accent lighting aim. COB module for clean, shadow-free beam pool. For retail displays, artwork, and feature accent from track position.
Wallwasher
Wall Wash · Even SurfaceAsymmetric optic module specifically designed to wash a vertical wall surface from a ceiling track position. Even top-to-bottom illumination with no bright stripe at the top. For feature walls, artwork corridors, and material display.
Tunable White — Every Fixture Its Own CCT
The defining feature of this system: each magnetic fixture is independently adjustable across the full 2700K–6500K range — simultaneously, on the same track.
↑ Example: four different fixtures on the same track, each at a different CCT — all set independently from the control app or DALI console
Four Control Options
Choose the control method that fits your installation — from DIP switch standalone to professional DALI and wireless smart home protocols.
DALI DT8
Per-fixture CCT and dimming via DALI Type 8 protocol. Individual addressing for BMS integration, scene programming, daylight linking, and energy metering. Standard for offices, hotels, and commercial projects.
Zigbee
Zigbee wireless protocol for smart home and building automation integration. Compatible with Zigbee hubs (Philips Hue Bridge, Samsung SmartThings, Home Assistant). Per-fixture CCT and dim from app or voice control.
BLE Mesh
Bluetooth Mesh wireless control. Each fixture individually addressable from a smartphone app. No WiFi hub required — BLE Mesh fixtures communicate directly. Alexa, Google Home, and Apple HomeKit compatible.
DIP Switch 3-in-1
Standalone control via onboard DIP switches — set CCT (warm/neutral/cool) and brightness level directly on the fixture driver without any external controller. Simple, reliable, no infrastructure needed for basic installations.
Why Specify 22mm Tunable White Track?
Per-Fixture CCT Control
Warm accent spotlight and cool task grille on the same track, each at precisely the right colour temperature for its function. Impossible with fixed-CCT track systems.
Four Fixture Types
Linear bars, grille spotlights, round spotlights, and wallwashers — the widest fixture variety in the Nucleo magnetic track range. One system covers every lighting layer in the space.
Reposition Anytime
Every fixture magnetically clips onto the track at any point and slides to any position without tools. Adapt the lighting layout to match room changes without ceiling work.
Recessed or Surface
Recessed track for a clean architectural ceiling finish. Surface track for quick installation on concrete slabs and false ceilings without a groove — same fixtures, same performance.
48V Safe Low Voltage
48V DC throughout — no mains voltage at any fixture connection. Safe to reposition fixtures without circuit isolation. Compliant with low-voltage installation regulations.
Human-Centric Ready
Tunable white enables circadian lighting schedules — warmer morning light, neutral midday, cooler afternoon boost, warm evening wind-down. Automated per-fixture via DALI or app.
Technical Features
📏 22mm Track Width
Wide enough to accommodate the connector body of all four fixture types including the wider linear bar and wallwasher bases. Sits in a 26mm ceiling groove when recessed.
⚡ 48V DC System
Full 48V DC bus throughout the track. Higher voltage than 12V/24V systems — allows longer track runs with consistent power delivery and supports higher-wattage fixture types.
🔗 L / T / X Joints
Mechanical and electrical corner connectors for L-junctions, T-junctions, and X-crossings — enabling complex multi-direction ceiling track layouts for large-space installations.
🎨 Finishes
Track body: white, black, and silver anodised options. Fixtures: black finish throughout the range — a bold, premium look that complements both light and dark ceiling surfaces.
🔒 Anti-Drop Clips
Secondary mechanical safety clip on all fixtures prevents accidental drop from the magnetic connection — mandatory for commercial and public-space ceiling installations above head height.
📐 SDCM <3
Tunable white chips binned to SDCM <3 at every CCT point in the 2700K–6500K range — consistent colour accuracy whether the fixture is at 2700K, 4000K, or 6500K.

Installation Guide
🔧 Track & System Installation
- Plan the track layout — mark the run positions on the ceiling with a laser level. For recessed track, cut a 26mm-wide groove at the required depth (30–35mm) using a plunge saw or multi-tool. For surface mount, mark fixing positions for the mounting clips at 400mm intervals.
- Route the 48V DC driver output cable from the driver position to the track feed entry point through the ceiling void. For DALI systems, additionally run the 2-core DALI signal cable. For BLE Mesh and Zigbee, only the 48V power cable is needed — the wireless signal travels without additional data cabling.
- For recessed track: press the 22mm track body into the groove. Secure with the supplied internal fixing clips every 400mm — clips engage from behind the track inside the groove. For surface track: fix mounting clips to ceiling at 400mm intervals, click the track into the clips.
- Install all corner connectors (L, T, X) where required. Feed the 48V cable from track section to track section using the inter-section electrical link connectors. Ensure all mechanical and electrical connections are fully engaged before closing any ceiling around the track.
- Connect the driver output to the track feed connector. For DALI: connect the signal cable from the DALI controller to the driver. Power on and verify the track energises correctly — test with a single known-good fixture before loading all fixtures onto the track.
- Clip all fixtures magnetically onto the track at their planned positions. Position each fixture type in its intended location (linear bars for ambient zone, grille spots for task positions, accent spots for display targets, wallwashers facing the wall to be washed). Proceed to commissioning.
🌡️ Tunable White Commissioning
- For DALI DT8 commissioning: with all fixtures on the powered track, run a DALI device scan. Each tunable white fixture appears as a DT8 (Type 8) device — two control channels per fixture: channel 1 for dim level, channel 2 for CCT. Assign short addresses according to your zone layout.
- Test each fixture's CCT range: send a CCT command of 2700K (full warm) to fixture 1. Verify the correct fixture shifts to warm white. Send 6500K. Verify it shifts to cool white. Any fixture not responding to CCT commands has a wiring or addressing issue.
- Programme CCT scenes: Scene 1 "Morning" — all fixtures 5000K, 80% brightness. Scene 2 "Work" — linear bars 4000K 70%, grille spots 5000K 100%, accent spots 3000K 60%. Scene 3 "Evening" — all fixtures 2700K, 40% brightness. Store and test each scene.
- For BLE Mesh/Zigbee commissioning: open the compatible smart home app (Tuya Smart, Home Assistant, or manufacturer app). Pair each fixture individually — each appears with a brightness slider and CCT temperature slider. Test CCT tuning across 2700K–6500K on each fixture. Group fixtures by zone for scene assignment.
- Create Tuya scenes — "Task Mode" (grille spots: 5000K, linear bars: 4000K), "Accent Mode" (spotlights: 2700K, wallwashers: 3500K, linear bars: off), "Full Bright" (all 4000K, 100%). Set time-triggered automations for each scene if required.
- Document the final fixture positions, addresses, scene assignments, and CCT settings for the project handover. For DALI commercial installations, include this in the building's lighting schedule. For Tuya residential projects, share the app login and scene guide with the client.
🌡️ When Every Fixture Knows What It Needs to Be
The best lighting design doesn't choose between warm and cool. It chooses both — simultaneously, from the same system, each light at the temperature that matches its function. The warm spotlight on the artwork. The cool grille light on the desk. The neutral wash on the wall. The ambient bar overhead, slightly warmer than task, slightly cooler than accent.
Standard fixed-CCT track forces a choice: install warm white and the desk feels intimate but the task work suffers; install cool white and the desk is functional but the space feels clinical. The tunable white system removes that choice entirely. Each fixture is set to exactly the right colour temperature for what it's illuminating — and those settings can change throughout the day, adapting to morning alertness requirements or evening relaxation mode.
Nucleo's 22mm Tunable White Magnetic Track is the specification answer for every project where this level of lighting intelligence is required. Four fixture types, any CCT, any position, any time — from one track that installs once and adapts indefinitely.
