Description
LED VU1 Linear Luminaire – Slim Track Spotlight, Individually Tiltable
1152 mm · white · 4000 K neutral white · CRI > 90 · 120°
With the LED VU1 linear luminaire you get a versatile track spotlight in a slim design. The standard 120° beam provides broad, even base brightness; in addition, each luminaire folds down and swivels individually from 0 to 30° sideways. You can adjust the light direction at any time without moving the luminaire along the track. For controllable installations the luminaire is also available in a DALI-2 version on request: it can then be dimmed steplessly and integrated into a central lighting control system.

Individually tiltable: light exactly where you need it
Individually tiltable means each luminaire can be folded down out of the track and then turned steplessly between 0° and 30° to the left or right. So you aim the light exactly where it is needed – at a shelf wall, a display or a workstation. This is especially handy when the interior changes: instead of rebuilding, you simply re-aim the luminaires.
Beam angles: which one suits your application?
Ex works the luminaire comes with a 120° optic – the classic angle for area lighting. For special requirements further beam angles are available on request. Here is what the individual versions do:
- 120° (standard) – very wide angle for even base light. First choice for normal ceiling heights up to about 4 m, for aisles, offices, sales rooms and workshops.
- 90° – slightly more focused than 120°. At the same height it puts more light on the floor and reduces stray light on the walls – good for aisles and shelf rows.
- 60° – medium angle for higher ceilings (approx. 4–6 m) or when a certain zone should be noticeably brighter than the rest of the room.
- 30° – narrow spot angle. Creates strong accents on individual products, displays or artworks and suits high ceilings because the light arrives concentrated below.
- 25° double (DS25°) – two narrow beams from one luminaire. Ideal when two opposite shelf sides of an aisle are to be lit at the same time.
- 25° asymmetric (L/R) – throws the light offset to the left or right. Perfect for wall shelves, wall pictures or window walls when the luminaire cannot hang directly in front.
- Opal cover 120° – a milky cover instead of a lens. The light is diffused softly and the luminous surface looks uniform – particularly low-glare for offices and anywhere soft light is desired.
As a rule of thumb: the higher the ceiling and the more targeted the light should be, the narrower the angle. For normal room heights and even brightness the standard 120° optic is the right choice.
Not sure which beam angle suits your room? Simply get in touch – we are happy to advise you and will find the right optic for your ceiling height and application together with you. The lenses for the different beam angles can be selected at no extra charge after consultation with us.
CRI > 90: colours like daylight
For the highest demands on colour fidelity: CRI > 90 also reveals subtle nuances that simpler light sources swallow. Clothing does not look faded, wood and leather keep their warm tone, food looks fresh. That makes this version ideal for shops, showrooms and display areas.
Long service life – L80 at 100,000 hours
The figure L80 at 100,000 hours describes how slowly the LEDs dim over time. Even after 100,000 operating hours they still emit at least 80 % of their original brightness. There is no sudden failure, only a very slow, barely visible decline – easy to plan for and low on maintenance.
High-quality LED chips by Sanan
A word on the LED manufacturer: Sanan Optoelectronics from Xiamen is not a no-name supplier but the largest producer of LED chips in China and one of the leading ones worldwide. Since its foundation in 2000 the listed company has grown into a vertically integrated group that makes everything itself, from wafer to finished chip – which secures consistent quality across large volumes. This luminaire benefits directly: high efficiency, very tight colour tolerances (SDCM < 5), stable colour rendering and a long service life of L80 at 100,000 hours. Cheap LED chips save money at purchase – good ones save it over the entire service life.
Mounting & track compatibility
Mounting is simple: the luminaire clicks onto a 3-phase busbar via its adapter – place, turn, done. Because the track carries three separate phases, you can switch different groups of luminaires independently. The adapter is compatible with the widespread systems Stucchi, Global, Staff, Unipro, Eutrac and Ivela as well as the EU universal standard; the design is Safety Class I.
Colour temperature 4000 K – neutral white
Neutral white light is businesslike and friendly at once – the all-rounder for sales rooms, boutiques, offices and exhibitions.
Why CRI > 90 delivers slightly fewer lumens
Fewer lumens at CRI > 90 – why? Higher colour rendering comes from a broader spectrum with a stronger red share. The eye perceives red light more weakly than green or yellow, and the necessary phosphor conversion causes extra losses. Together these slightly reduce measured luminous flux and efficacy (lm/W). The gain: colours, fabrics and materials look exactly as they really are.
Power steps & luminous flux
| Power step | Power | Luminous flux |
|---|---|---|
| Step 1 (maximum) | 48 W | 7,680 lm |
| Step 2 | 40 W | 6,400 lm |
| Step 3 | 34 W | 5,440 lm |
| Step 4 (minimum) | 27 W | 4,320 lm |
Power is selected directly at the luminaire via switch – so you match brightness to the room without additional devices and save energy permanently.

Applications
Typical locations are shops, boutiques, supermarkets, showrooms, galleries, offices, conference rooms, corridors and reception areas as well as workshops and exhibition halls. Because the luminaire simply clicks onto the track, the lighting can change along with the room – new shelves, new ranges or a new layout mean no electrical rework, just repositioning and re-aiming the luminaires.
