The Zen Linear Diffused Light is built for ceilings where the track profile itself needs to disappear as much as the light source does — at H12mm, this ambient fixture sits almost flat against the 21mm Zen track, considerably thinner than the equivalent fixture in most magnetic track systems. Available as the 10W S20-E300 (L306mm) and the 20W S20-E600 (L600mm), both with Bluetooth app control tuning colour temperature continuously from 2700K to 6500K. Black or White.

Most ambient track lighting trades one thing for another: either the fixture profile is slim and the light output modest, or the output is strong and the fixture body is noticeably thicker. The Zen system's 21mm track and H12mm fixture profile — both thinner than the comparable NEUE system's 22mm track and taller fixture bodies — hold that thinness while still delivering usable ambient output, at 10W or 20W depending on the run length. This is the specification for a ceiling detail where the track reveal itself has to stay minimal, not just the visible light source.

Length selection follows the section of ceiling being lit: the 306mm S20-E300 suits shorter runs — a compact alcove, a single wardrobe interior, a short accent zone — while the 600mm S20-E600 covers a standard room bay from one fixture. Both connect to the same Bluetooth control ecosystem as every other Zen fixture, meaning a single Smart Life app session governs dimming and colour temperature across an entire installation regardless of which specific Zen products are mixed on the run.

The full 2700K-6500K tuning range, available via app on every Zen fixture rather than fixed at order time, means a single fixture can serve a warm evening mood and a neutral daytime setting without needing two separate CCT specifications purchased in advance — a genuine advantage over systems where colour temperature is a fixed factory choice.

• S20-E300 (10W, 306mm): Alcoves, wardrobes, short accent runs
• S20-E600 (20W, 600mm): Standard room bay ambient from a single fixture

How does the Zen system's tunable colour temperature actually work day to day?

Every Zen fixture connects to the Smart Life app via Bluetooth, and colour temperature is adjusted continuously across the full 2700K-6500K range from the app rather than being fixed at purchase. This means a warm evening setting and a neutral daytime setting are both available from the same physical fixture, changed on demand rather than requiring separate CCT-specific units.

Why choose Zen over a standard magnetic track ambient fixture for a slim ceiling detail?

The Zen system's 21mm track and H12mm fixture profile are built specifically for installations where the ceiling reveal needs to stay minimal — thinner than comparable systems where the track and fixture body are more substantial. Where that ultra-thin profile is the priority, Zen is the correct specification.
