Description
LED VU1 Linear Luminaire – Slim Track Spotlight, Individually Tiltable
578 mm · black · 4000 K neutral white · CRI > 90 · 120°
The LED VU1 linear luminaire combines a modern, flat design with high light output. Its standard 120° beam lights large areas softly and with little glare. Because the luminaire folds out and tilts individually up to 30°, you decide whether light spreads evenly through the room or highlights a specific area. 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
The luminaire is not fixed rigidly. It folds down and can then be tilted individually by up to 30° to the side. With one and the same luminaire you can either light a surface evenly or highlight a specific zone. If you rearrange the space later, you realign the light within seconds – no tools, no rebuilding.
Beam angles: which one suits your application?
As standard the VU1 emits at 120°. This is a very wide angle that spreads light over a large area and provides even base brightness. Depending on ceiling height and task, narrower or special optics are available on request – here is an overview of what suits what:
- 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
With CRI > 90 the luminaire achieves colour rendering close to daylight. Reds, skin tones and fine material differences become visible instead of looking washed out. In boutiques, fashion stores, jewellers, bakeries and galleries this often decides a sale: goods that look natural and premium are more likely to be bought.
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
The difference in luminous flux between CRI > 90 and CRI > 80 has a simple background: the better the colour rendering, the more complete the spectrum has to be. The increased red content, however, contributes less to measured brightness because the eye is less responsive there. Together with conversion losses this results in slightly fewer lumens per watt – a trade that pays off wherever colours must look exact.
Black housing: luminous flux & look
Why does the black version state fewer lumens than the white one? The reason is purely optical: light hitting bright surfaces inside the housing is reflected outward with almost no loss. Dark surfaces, by contrast, absorb a share of the light. That share never leaves the luminaire and is missing from the lumen figure – efficacy in lm/W drops slightly as a result. The trade-off: the black look is more restrained, glares less and suits dark ceilings and premium store concepts perfectly.
Power steps & luminous flux
| Power step | Power | Luminous flux |
|---|---|---|
| Step 1 (maximum) | 24 W | 3,480 lm |
| Step 2 | 20 W | 2,900 lm |
| Step 3 | 17 W | 2,465 lm |
| Step 4 (minimum) | 14 W | 2,030 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
The VU1 is a true all-rounder for interiors with a track system. In retail it lights sales floors and shelf aisles evenly and highlights individual merchandise areas with tilted luminaires. In the office it provides pleasant working light above desks and meeting islands. In galleries, exhibitions and showrooms the light can be flexibly aimed at changing exhibits. Corridors, reception areas, workshops and car dealerships also benefit from the mix of wide base light and individually tiltable luminaires.
