MDT ® / MST ® - an endless holiday for your eyes
With MDT ® (Micro Downlight Technology) Regent has revolutionised glare free lighting for work stations. This solution originated from the need to create good lighting design with reduced costs. Conventional reflectors for glare free lighting are relatively large and expensive specular louvres in metal or plastic, which, because of their geometry/dimensions, require big light sources. Regent has developed the perfect solution, allround glare free lighting with minimal louvre height and optimal production costs! The trick: the reflector in the form of a downlight has been miniaturised, then pressed and punched hundreds of times in light aluminium sheeting.
The direct light on the work station is then glare free in all directions and conform to international standards. The main light is diffused from ceiling to floor thanks to a secondary reflector.
With a height of only a few centimeters, MDT ® allows greater visual comfort especially at work stations. Eye strain, tiredness and headaches are a thing tof he past!


- LEVEL, HELLO, REVOLUX, FOGLIA
Which Regent luminaires are equipped with MDT®?
MDT ® (Micro Downlight Technology) was used for the first time in 2001 for the development of LEVEL and allowed a luminaire height of only 4 centimeters! LEVEL offers perfect luminaires for work stations in different versions: suspension, system and wall luminaire, standing uplighter.
A lighting system with maximal modularity and unexpected freedom for light planning. HELLO has two tracks that hold the light band suspended under the ceiling. The free space in between can remain empty or be equipped with different light elements.
REVOLUX is a modular ceiling recessed luminaire. The light coming from the centre positioned fluorescent lamp is distributed homogeneously in the space thanks to a secondary reflector. MDT ® guarantees glare-free light, even when viewed directly!
When the MDT ® louvre is reduced to its minimum and realized as self supporting construction, the result is FOGLIA.

With MDT® light creates comfort.
With MDT ® (Micro Downlight Technology) Regent has revolutionised glare free lighting.
The best example: the lighting system Level. What may look like a hole in a metal sheet, is actually a mini downlighter that functions like a light dome, refracting light. With the light directing element, deep-drawn from aluminium reflector material and a translucent film inlay reflector, MDT ® ensures perfect allround glare free lighting. The result: more comfort at work stations.
And all this in one luminaire body - 4 centimetres high - including light source, wiring and ballast. One dimension, which guarantees absolute planning reliability and design freedom.

The difference between MDT® and MST®
The louvre MST ® (Micro Slot Technology) is based on the same idea as MDT ® with the difference that the round form of MDT has been „drawn in the length“. The result is a Slot.
The slots guarantee glare-free lighting on the transverse axis and a great quantity of direct light along the longitudinal axis. It means that MST ® is the ideal solution to the need of glare-free lighting parallel to the luminaire-axis.
An optimal application field: the shelf corridor of a sale point. The direct light should reach on both sides the displayed products, without blinding the customers.
MST ® and a fitting saddle reflector are the ideal complementary solution for the bisymmetric ICE GRID luminaire!
