Description
LED VU1 Linear Luminaire – Slim Track Spotlight, Individually Tiltable
1438 mm · black · 6000 K cool white · CRI > 90 · 120°
The LED VU1 linear luminaire is a slim linear spotlight for the 3-phase track. With a 120° beam it delivers soft, wide-area light, and it can be folded down and tilted individually by up to 30° to the left or right. That way you light surfaces evenly and aim the light at shelves, goods or walls whenever needed. 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
Every VU1 folds out and swivels individually 0–30° to the left or right. The everyday benefit: you light shelf fronts, display tables or wall surfaces precisely without installing extra spotlights. Since each luminaire is adjustable on its own, you can combine even base light and pronounced accents on a single track.
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
CRI > 90 means colours appear as they truly are. A full red share in the spectrum makes textiles, food and decoration look vivid and appetising. Wherever colour fidelity counts – fashion, jewellery, cosmetics, delicatessen or exhibitions – this version is the right choice.
Long service life – L80 at 100,000 hours
What does L80 / 100,000 hours mean? Simply this: after 100,000 hours of operation the luminaire still delivers at least 80 % of its day-one brightness. At ten hours of use per day that is more than 27 years. Illumination therefore stays virtually constant for a very long time.
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
The VU1 is fitted directly into the busbar using a 3-phase adapter – no drilling, no cable routing. The three phases (L1, L2, L3) let you switch several lighting groups on the same track separately, for example general light and window light. The adapter fits the common European track systems: Stucchi, Global, Staff, Unipro, Eutrac, Ivela and the EU universal standard. The luminaire is Safety Class I with protective earth.
Colour temperature 6000 K – cool white
Cool white light provides maximum brightness and contrast – proven in storage, production and high halls.
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.
Black housing: luminous flux & look
With a black housing the luminous flux is deliberately a little lower than with white – this is not a difference in quality but physics. Inside the luminaire, light is redirected several times before it exits. Bright surfaces reflect very well, dark surfaces absorb part of it and release it as heat. The result: slightly fewer lumens and marginally lower efficacy (lm/W). Anyone looking for an unobtrusive, low-glare appearance still makes the right choice with black.
Power steps & luminous flux
| Power step | Power | Luminous flux |
|---|---|---|
| Step 1 (maximum) | 60 W | 8,700 lm |
| Step 2 | 50 W | 7,250 lm |
| Step 3 | 42 W | 6,090 lm |
| Step 4 (minimum) | 33 W | 4,785 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.
