Rectas Catalog |
Rectas is the Latin word for straight lines. That is exactly how this series of circular and recyclable LED luminaries was intended: technical decorative, with direct or indirect light. There are 6 versions, all named after famous thinkers and philosophers: Aurelius, Bredero, Cicero, Diderot, Erasmus and Freud. The fixtures are made of aluminium with black or cherry wood details. Thanks to the use of LED heat collectors very high luminous fluxes are reached. Available in different lengths.


Now also in LED
Our outdoor fixtures, made in practically indestructible 4mm thick galvanized steel, is now also suitable for LED.

Keen Light design recently eased the citizen Hall in the Town Hall of the municipality of Hoogeveen. This municipality decided, after bad experiences with led fixtures of inferior quality, to the existing lighting in the citizen Hall to replace the Keen fixtures Minos 99, equipped with the specially developed Cool Led technology.
The existing 108 recessed fixtures (equipped with a persglas bulb of 100W)
54 hanging fixtures have been replaced by Minos 99 with a consumption of just 24W.
The illumination is very satisfactory and one is full of praise for the quality of the fixtures. Additional advantage: the energy saving is about 85 percent.
Frisian Outdoor Lighting
Friesland: a province in the North of the Netherlands with its own identity and language-the Frysk. The landscape is wide and full of water. The skies variegated. The people are tough, earthy and quirky. They also high personal requirements. With this background designed Egbert Keen an outdoor lighting program consisting of three series: ' Boppe ' (the top), ' Irish ' (Earth) and ' Attaches ' (robust). These three Frisian words are characteristic of the quality and the whimsy of the entire program. Series ' Boppe ' is made of black epoxy-coated aluminum, the series ' Irish ' en'Hecht ' out of galvanized steel or black epoxy coated zinc plated steel.

Influence of light and color
|
Perceiving colors belongs to the most ordinary things of everyday life. Everything is color. Color is just as form, an important tool to recognize the objects around us. Color is like light so self-evident that we scarcely think about it while the world is in fact completely colorless. The visible world consists of colorless matter. Light is the only source that colors.

What is actually light
|
The word ' light ' is a simple word. But what a wealth of meaning behind hiding behind this concept. Because light is reflection, color, is a myth and is pure emotion. In addition, also light for safety. ' We all know what light is, but it's not easy to tell what it is... ' Rarely has anyone so right in my eyes as the English scholar Dr. Samuel Johnson (1709-1784).

Induction lamps |
The operation of Fluorescent induction lamps – is very similar to ordinary fluorescent lamps. However, the electronic link happens via electrodes but using an electromagnetic field. The performance is similar to the fluorescent lamps: 85 Lm/W and a color rendering of 80-85.

There are several executions: balloon-shaped, circular and rectangular. On or to the tubes are flush; These are connected with an electronic ballast.

In conventional gas discharge lamps limit the electrodes the lifespan of the bulbs. An electrodeless lamp knows this limiting factor not and therefore has a very long life. The lamps with an external ballast after 100,000 hours still ± 70 percent of its original luminous flux. To achieve this life, the quality of the ballast is very important. Because the light sources last longer than the useful life of the fixtures are maintenance costs, replacement costs and environmental impact almost nil.
