The colour of the light that shines out is determined by the triphosphorus coating on the inside of the lamps themselves. Top-quality Philips triphosphorus powders are used for the production of Lumco lamps. These powders meet the most stringent quality standards and have a high CRI (colour rendering index) of >85 and are the same fluorescent powders that are used in the manufacture of conventional fluorescent lamps. As a result, the white colours given off by Lumco lamps fit in perfectly with the white colours of conventional fluorescent lamps.
The white colours and RGB colours in the Lumco range of colours are available as standard. A wide range of other colours can be ordered on request.

White colours

The white colour references are defined as a function of their colour temperature expressed in Kelvins. The higher the colour temperature, the colder the light. The lower the Kelvin value, the warmer the light. The average colour temperature of daylight is 5600K. Lumco lamps are available in the following shades of white:

2700K / ref. 827 / comfort white = very warm white.
With comfort white, an attractively soft atmosphere can be created. This colour is often used in private homes, hotels, restaurants etc. Comfort white delivers excellent results in spaces with white walls or light wood walls, but is best avoided in areas when a high level of daylight may shine in, as the light given off becomes more yellow when combined with too much daylight. The colour of comfort white can be compared with the white light given off by incandescent bulbs.

3000K / ref. 830 / warm white
Warm white is a pleasant shade of white that can be used for many applications. It is a more neutral shade of white compared with comfort white and does not have any yellow nuances. Warm white is much used in offices, meeting rooms, corridors, etc. Warm white combined with daylight gives an interior a warm look without too many contrasts. The colour of warm white can be compared with the white light given off by halogen lamps.

4000K / ref. 840 / neutral white
Neutral white is a soft, colder shade of white that can be used neutrally in spaces where a more pure and technical effect has to be created, such as laboratories, petrol stations and other technical areas. The colours of stained glass windows or strongly coloured walls and ceilings are displayed perfectly by neutral white light. It is also a suitable shade for lighting areas containing cold materials, such as aluminium panels, glass etc.

6500K / ref. 865 / daylight
The daylight colour gives off a very cold shade of white and is often used in outdoor settings. However, this shade of white is also suitable for specific indoor applications, such as in skylights where the aim is to create artificial daylight, or in areas where certain contrasts have to be emphasised.
Daylight combined with other colour shades also creates surprising results. Combined with other sources of light that give off warm shades of white, a blue nuance can be obtained.

RGB colours
Red ref. 804
Green ref. 803
Blue ref. 801
Lumco lamps that run in parallel next to one another can be used in the 3 RGB colours of red, green and blue. By mixing these 3 colours, countless other colours can be created, resulting in a separate atmosphere and emotion being created on the ceiling and in the room.

A few examples as illustration:
Red (100%) + Green (100%) = Yellow
Red (100%) + Green (50%) = Orange
Green (100%) + Blue (100%) = Cyan
Red (40%) + Green (60%) + Blue (100%) = Sky Blue
Red (100%) + Blue (100%) = Magenta
Red (100%) + Green (100%) + Blue (100%) = Neutral White

Other colours
Depending on the fluorescent colours used, as well as the required diameters or the use of mass-coloured glass, many other colours can be given off by Lumco lamps.
These colours are available on request.
