Product information "Linessa 2L"

Illuxtron Linessa 2L


Less is more. Or in the case of Linessa: Making technical innovation affordable by clever product design. The end result is a lighting panel that only has 7 parts and no glue, screws or tape. Linessa has a very minimalist design. At the end of life it is very easy to take the product apart or implement a new LED module. In this scenario we minimize the waste of materials, keeping it as low as possible. Compare this to hazardous fluorescent lamps that need to be replaced frequently.

Bartenbach Darklight Technology - UGR11

Normal diffuser panels distribute light in all directions and create a lot of glare. The Bartenbach Institute helped us to develop special reflector cups that ensure all of the light is reflected in ways that you need. Less glare in an office means less mistakes, less head aches and greater wellbeing for your employees.

Best in class Lux/Watt

The normal amount of lux for an office desk is around 500Lux. With the Linessa series this can be achieved with less energy. Compared to a normal diffuser LED panel of 25-40W it saves 25-40%.

No Multi Shadows

As soon as you try to focus light on to an object with multiple reflectors there will be an annoying multi shadow effect. By using 10 times more reflector cups than normal this effect will dissapear.

Bespoke Versions

The metal plate can be easily changed to different dimensions. It is even possible to integrate a sensor into the plate or air sleeves for ventilation.

Less Light Pressure

Existing LED reflector technology panels have low glare, but were uncomfortable to work under. By adding more reflector cups we managed to achieve the best comfort available in any LED panel on the market. The pressure from the LEDs is divided by an enormous amount of LEDs.

Features and benefits
• Application of Bartenbach's special Dark Light Technology with ultra-low UGR rating.
• Ideal for office applications
• Extremely low wattage for necessary lux level

FAQs rund um LED-Leuchten
Sammlung über häufig gestellte Fragen rund um LED-Leuchten (Nicht LED-Lampen)

Recessed ceiling spotlights/downlights are available in many different versions. These parameters primarily define this product family: 
  • Hole diameter - We recommend selecting the spots first, then drilling the holes. Otherwise the limitation is predetermined Output 
  • Light output in lumens, or wattage. How much light is needed in the room. There is no general answer to this question. Use the following link for the project enquiry 
  • Installation depth - usually a mandatory requirement in terms of drill hole depth or distance from suspended ceiling. 
  • Color temperature dimmability - We recommend modern options such as DALI or Casambi. 
  • Beam angle - For uniform room illumination. Usually determined by the distribution of the spots in the room and the room height. 
  • Fastening - Installation in false ceiling or concrete ceiling Glare - Depending on the viewing angle, lower LEDs in the spotlight can often no longer be perceived as a bright point of light, thus ensuring pleasant lighting.

If you have a lighting project and would like to use downlights, please use the link provided for our project enquiry form. We will try to answer all your questions.


It is a challenging topic. A basic distinction can be made between these types of LED luminaires: 
  • designer luminaires (the eye pays the price regardless of the technical design) 
  • luminaires with replaceable LED light sources (less sustainable) 
  • luminaires with permanently integrated LED boards and their own LED driver (most sustainable solution with the best efficiency and flexible options for dimming via DALI, 1-10V, etc.) 
  • technical luminaires with special lighting tasks such as LED downlights.

Colloquially, they are often equated with each other. However, lighting experts make a clear distinction between lamps and luminaires.

This also applies to LEDs. A lamp is the typical light source (e.g. a light bulb) that is screwed into the socket of a luminaire. That already explains it. Luminaire is the system consisting of lamp, base, lampshade, etc. LED luminaires are available with a replaceable LED light source (lamp) and with a permanently installed LED module. The advantages and disadvantages can be found in another FAQ.
