Kelvin
-
Kelvin (K) is the unit that indicates the colour temperature of a light source. The less kelvin, the warmer the light colour. The more kelvin, the colder the light colour. At psmlighting we make a distinction between three types of colour temperature:Warm white: 2700K - especially for atmospheric lighting in homes, restaurants and hotels.Neutral white: 3000K - often i...

Can I add lamps to a rail system afterwards?
-
You can certainly add lamps to a rail, but the following points should be taken into account:-A rail of 12V: the number of lamps depends on the power of the transformer.-A rail of 230V: you may not exceed the maximum current of the rail.

Can I order customised profiles ?
-
A standard product does not always fit perfectly where you want it. That is why we adapt the fixtures to your wishes and the dimensions of your décor. Please understand: customised profiles cannot be returned after sale.

Artwork lighting
-
With artwork lighting you literally put a painting in the spotlight. By placing luminaires above or around the painting, everyone can see your work of art in its full glory.

Sensor
-
Sensors act as a switch to turn certain electrical circuits and lamps on or off. Sensors are not operated by hand, but they detect movements, heat and so on by themselves. This can be very useful, for example to automatically switch off the light in a room where there is no movement.

Mirror lighting
-
When you stand in front of a bathroom mirror, you need powerful and honest light. That is what mirror lighting is for. These fixtures are located above or around the mirror and ensure that you can see yourself in full detail.

Waterproof
-
Waterproof means that water cannot penetrate into a device or a terminal. This application is useful in environments such as the bathroom or garden where fixtures may come into contact with water.

Railsystem
-
In a rail system, we place a rail in which we click one or more lighting fixtures. This system can be attached to a ceiling or suspended as a pendant.

IP value
-
The two-digit IP (International Protection) value indicates how much an electrical appliance is protected against solid objects and water. The first digit can have a value from zero to six and indicates protection against solid objects. The second digit goes from zero to eight and shows the protection against water. The higher the number, the better the protection.

Light distribution curve
-
The light distribution curve shows a diagram of how the light from a light source spreads. The shape in the drawing is actually the form that light adopts when it leaves its source, for example a lamp. The light distribution curve shows two lines: a dotted line (the side view) and a full line (the front view). If there is only a full line on the curve, it means that both lines coincide.

LED
-
LED stands for Light Emitting Diode. It is a semiconductor that emits light when you send a certain electric current through it. The colour of the LED does not depend on the housing, but on the type of material of which the conductor is made. As a comparison: an incandescent lamp bulb emits light because a filament is heated. This immediately shows one of the major differences with a LED...

RGB
-
Red, Green and Blue are the main colours in the RGB colour system. By mixing these colours, you can form all the other colours. The same applies to RGB lighting.

Lumen
-
Lumen (lm) is the unit for luminous flux. In other words, it is the amount of light that a point of light emits in all directions. So the brightness of a point of light is measured, independent of the direction of the light beam.

Lux
-
Lux is the unit of illuminance. It is the amount of light that falls on a specific surface. Lux is the lumen per square meter. In contrast to the luminous intensity (candela), the distance to the light source plays an important role here. The closer, the more lux and vice versa.

CRI
-
The CRI value indicates how truthfully a light source represents the environment. Daylight has a maximum value of 100. The lower the CRI value, the greyer an object will look when illuminated with this light.

Colour spectrum
-
Normal sunlight looks white, but it actually contains all the colours you can see in a rainbow and some other colours that are invisible for the human eye. The colour spectrum contains the following colours: red, orange, yellow, green, blue, indigo, violet and the invisible colours. All these colours can be mixed to create new ones.

Colour
-
Light consists of different wavelengths, each of which has a different colour. When we see an object in the colour red, it is because it absorbs all other light, except for the red wavelength.

Candela
-
Candela (cd) is the unit used to indicate how much light a light source emits in a certain direction. In other words: the light intensity. This is determined by the opening angle. The larger the angle, the more Candela. As a comparison: Candela is Latin for candle. 1 cd corresponds approximately to the light intensity of a candle.
