| Average life span | 13000h | ? 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. |
| Brand | Unbranded | ? If the product is unbranded, we do not have a regular supplier for it. Therefore, the product version may slightly vary. |
| Colour code | 830 |
?
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 |
| Colour rendering index Ra | >80 |
?
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 | 3000K |
?
Colour temperature is expressed in kelvin (K). The higher the colour temperature, the cooler the impression of the light: 2700K: extra warm white
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.
