what is special about
our solution?

Invention of the worldwide first lightsource-luminaire system at the cross section of a penny

The fluorescent tube is transfered into a light fixture based on brand new socketable systems

Enabling new ways for existing, similar/adjacent or new market players to interpeatate lighting and integrate or make a lighting fixture

At the fraction of the size, weight and cost as state of the art solutions



LTwo® stands for Light Tube with Optics.

A modular, miniaturised light source-luminaire system with a diameter of just 16.4 mm, based on a T5 tube. 13 high quality precision optics from always one form factor and a wide range of accessories for all lighting applications.

The lamp becomes a luminaire in the simplest way. Professional lighting thus becomes a plug & play solution and can be integrated into materials and building structures of any kind without much effort. We thus make it possible for anyone to use professional light in any application and to produce luminaires themselves.

The product has a newly developed multifunctional lamp/light holder for easy, toolfree, magnetic mounting and angle adjustment in +/-20° as well as a locking mechanism. A coded system allows safe operation of lamp luminaires with different operating currents in Constant Voltage or Constant Current. Available in 140, 280, 560, 840, 1120, 1400mm lengths with a lumen output of 3000 lm/m. Minimal material consumption (180g/m), interchangeability, recyclability and high effi ciency (up to 180lm/W) make LTwo® very environmentally friendly.

Lumami® DESK

Lumami® DESK - A desk lamp with the qualities of a pendant luminaire

Sometimes you have to compromise to create the ideal. Ideality is achieving the maximum of function by using the minimum of resources.

Lumami® DESK combines the best features of all lighting systems for an ideal result! The absolutely homogeneous and complete illumination of the workplace in unprecedented quality!

Advantages of a pendant lamp, combined with the individuality of a desk lamp and the high performance of further lighting systems like grid ceiling or floor luminaires, for ideal workplace lighting, in compliance with DIN standard EN 12464-1

Lighting intensity >750 lux
Glare limitation through UGR <16
Uniformity through special developed optic for Lumami® Desk

At first glance, this may look like something you need to get used to and it may raise some questions... and that‘s what it‘s supposed to do!

But from the result you will be convinced!

  • Our optical modules come in an efficiency range of 65% to 90%, depending on the optic. This is industry standard or better. Especially, to consider that our precision optics use the light more efficient in the indented application. Therefore, the product is much better tailored to meet and exceed green building standards in architectural and lighting design

  • Based on all of the above our product, due to its miniaturization, uses about 90% less space and raw material as comparable industry products. This does not only protect the scarce resources of our environment, as well it reduces overall carbon emissions in storage, packaging and transport

  • In recessed application the product will cause no additional measures for structural modifications which normally lead to additional use of construction material

  • LTwo® uses a low number of parts with recycling friendly materials. Having no screws it can easily be dis-assembled. Aluminum: 124 gr/m., Plastic: 49,5 gr/m, Electronic comp. 5,5gr/m.
