LED VU3 Linear Luminaire – Central Light + Two Tiltable Spots

1200 mm · black · 5000 K daylight white · CRI > 90

This linear luminaire for 3-phase track systems merges wide central lighting with two tiltable accent spots. The result is even base illumination that can be focused precisely on individual areas whenever needed – ideal for retail, office and workshop environments. For controllable lighting this linear luminaire is optionally available as a DALI-2 version. It can then be dimmed steplessly and integrated conveniently into modern light-management and building-control systems.

Key benefits at a glance

Features in detail

• Colour rendering CRI > 90 for natural, rich colours
• Switchable power 48 W / 40 W / 34 W / 27 W without tools
• Optionally DALI-2 dimmable on request
• For 3-phase track – compatible with common track systems
• Rugged aluminium housing in black, PMMA lens, IK04

Central light + two tiltable spots

The central light emits at a wide 100° beam and lays down an even base brightness across the room. The two outer spots use a 30° × 90° optic and tilt steplessly between 0° and 30°, so you can place accents exactly where needed without moving the luminaire.

For shelf and aisle lighting the tiltable spots are ideal – the light can be aimed exactly at shelf boards and displays, presenting goods along the aisles bright and appealing.

Perfect colour rendering for retail & boutiques

For the highest demands on colour fidelity: CRI > 90 reveals subtle nuances that weaker light sources swallow. In fashion boutiques, jewellery stores, bakeries and showrooms colours appear rich and true to life – ideal wherever perfect colour rendering drives sales.

Long service life – L80 at 100,000 hours

100,000 hours at L80 means that only after this long operating period does luminous flux fall below 80 % of the initial value. Until then illumination stays almost constant – a clear benefit for operators focused on low maintenance and long service life.

High-quality LED chips by Sanan

At the heart of the luminaire are LED chips by Sanan – one of the largest and most respected LED chip manufacturers in the world. The listed company from Xiamen produces several hundred billion LED chips per year and supplies international technology corporations, among others. Sanan chips stand for excellent efficiency, tight colour tolerances and high operational reliability – reflected in even light, stable colour rendering and long service life.

Mounting & track compatibility

Mounted via a track adapter on a 3-phase busbar, the luminaire can be positioned freely along the track and switched separately across the three phases. It fits the widespread track systems Stucchi, Global, Staff, Unipro, Eutrac, Ivela and the EU universal standard. Up to 16 luminaires may run per circuit (< 800 W). Connection is Safety Class I with protective earth.

Colour temperature 5000 K – daylight white

Daylight white light is crisp and activating – ideal for technical work, assembly, labs and visually demanding areas.

Why CRI > 90 delivers slightly fewer lumens

The fact that CRI > 90 delivers somewhat fewer lumens than CRI > 80 is directly linked to its better colour rendering. To render colours true to life, the LED needs a broader spectrum with an increased red share. This share contributes less to measured brightness because the eye is less responsive there, and the required conversion causes extra losses. The result is a slightly lower luminous flux and somewhat lower efficacy (lm/W) – a worthwhile trade wherever perfect colours matter more than the last lumen.

Black housing: luminous flux & look

Why does the black-housing version deliver slightly fewer lumens? The reason lies in the reflection inside the luminaire: bright, white surfaces reflect the generated light very efficiently and direct almost all of it outward. Dark or black surfaces, by contrast, absorb part of the light that hits the internal surfaces – this portion does not leave the luminaire and is lost as heat. That is why the luminous flux, and therefore the efficacy in lm/W, is somewhat lower with a black housing than with a white one. In return, the black version appears less glaring and more discreet – a deliberately chosen advantage in boutiques, shops and premium settings where an understated, elegant look is desired.
