? The ANSI code on a lamp or device indicates that the product meets ANSI (American National Standards Institute) standards. ANSI is an organisation that develops standards for performance, dimensions and safety. Lamps with corresponding ANSI codes are interchangeable.

? The life span of a party of lamps of which 50% of the lamps will continue to function. Sometimes, incandescent or halogen lamps may become defective more quickly, but in case 50% of the lamps do still reach the lifespan, the lamps are still OK.

? The wider the light beam, the larger the illuminated surface. Brightness decreases as the beam widens, since the light is divided over a larger area.
For creating high contrasts it is therefore recommended to apply smaller light beams. However, contrasts that are too high can be distracting and can cause adjustment problems for the eye, which can be tiring. On the other hand, too little contrast creates a dull and flat impression.

? Light colour is often represented with a 3 digit number. The first digit indicates the CRI (Colour Rendering Index) or CRI Ra value:
5 = 50-59
6 = 60-69
7 = 70-79
8 = 80-89
9 = 90-99
The last 2 digits are for colour temperature.
The higher the colour temperature, the cooler the impression of light.
Warm white creates a cosy, welcoming atmosphere. Neutral cool-white creates a more businesslike atmosphere.
Low lighting levels in interior must be obtained with warm-white light. If a very high level of light is needed, this must be achieved with neutral or cool white light.
2700K extra warm white
3000K warm white
3500K neutral white
4000K cool white
5000-5500K daylight
6000K cool daylight

? Light sources can be classified on the basis of their colour rendering properties. The unit for colour rendering is called CRI (Colour Rendering Index, or CRI Ra value). The scale of the Ra is from 50 to 100.
Ra = 90-100 excellent colour rendering properties
Ra = 80-90 good colour rendering properties
Ra = 60-80 moderate colour rendering properties
Ra <60 poor colour rendering properties
Fluorescent and PL lamps with an equal power, the luminous flux of Ra 90-100 tubes is typically 20% lower.

Colour temperature is expressed in kelvin (K). The higher the colour temperature, the cooler the impression of the light:

2700K: extra warm white
3000K: warm white
3500K: neutral white
4000K: cool white
5000-5500K: daylight
6000K: cool daylight

Extra warm white creates a warm, inviting atmosphere (e.g. hotel, living room, and catering). Warm white can be used for a pleasant atmosphere (e.g. retail and office). Neutral cool white creates a more businesslike atmosphere, this color gives a sterile atmosphere.
Low lighting levels are obtained in interior with warm white light. If a very high level of light is needed, neutral or cool white light is a good choice.

? A front glass has the advantage that the inner reflector cannot contaminate it.
Some lamps have a matte or coloured glass front.

? Many lamps are available in 2 versions: heat forwards or heat backwards. Please note the user manual of the fixture!

? For many applications, there are special lamps. Maybe your application there and there is a more suitable lamp available.

? Product length in millimetres. For fluorescent tubes, this excludes the metal pins on the end unless otherwise stated.

? The amount of light transmitted by the light source per second. The unit of luminous flux is the lumen (lm).

? Many lamps have a UV filter against discolouration. This filter is often recognisable as a bluish glow over the lamp. If a lamp has a UV filter, this is indicated on its packaging and, in most cases, also on the lamp itself.
