? These lamps can be applied directly to mains voltage 230V AC (alternating current)

? 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.

? 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.
