Decoration and accent lighting

The steam of metal halide lamp of low power (20 to 150 W) is compact and its light is easily focus. If a luminous flux per unit is required, it is an effective alternative to the lamp incandescent and halogen for decoration lighting lamp, for example in the reception halls and showrooms. Indirect luminaires equipped with lamps to metal halide of average power (150 W, 250 W) realize a saving of 70% compared to halogen lamps.

Lighting a table or documents posted on the walls

A light enough on the table cannot be achieved only by a specific lighting.
To get a uniform lighting on the table, the tube, with its elongated shape, is the most appropriate. The CFLs can also agree, but will be more easily “circles” of light and lighting will be less uniform.


A class is lit by:

  • general lighting: 9 lights low luminance of 2 x 36 W each.
  • light table: 3 asymmetric lamps of 50W each.

The average lighting measured in the class is 420 lux for a general power of 9 W/m². The level of illumination of the table, when his specific light is on, is 436 lux. When only the general lighting, the table average lighting level is 99 lux, which is clearly insufficient.
The CFLs The choice of fluorescent lamps (fluorescent tube type) and the LEDs will be interesting to realize an effective dimming depending on the level of natural light in the concerned local. Easily lamps dimmable In the premises who have access to natural light (presence of Bay window), the choice of lamp will take into account compatibility with the “dimming” to adopt management of the luminous flow according to the natural light.

Apart from the CFL 4 pin with electronic ballast, this type of lamp to 2 pin and screw cannot be effectively dimmee.

Iodides and metal halide

This type of lamp can be dimmed to the maximum 50% (and often there are problems of color (collor shift) in the case of dimmingchange.) If the windows are large sizes, the choice of iodide or metal halide lamps will not make sense.

Selection according to the time of operation and the frequency of power on/off
