| Artikelnummer fabrikant | 428772 | ? Manufacturer's part number. |
| Average life span | 4000h | ? 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. |
| Beam angle | 36° |
?
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. |
| Brand | Osram | ? If the product is unbranded, we do not have a regular supplier for it. Therefore, the product version may slightly vary. |
| Colour rendering index Ra | 100 |
?
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.

| Length | 45mm |
?
Product length in millimetres. For fluorescent tubes, this excludes the metal pins on the end unless otherwise stated. |
| Luminous intensity | 2200cd | ? The light flux that is emitted in a certain direction. The unit of luminous intensity is the candela (cd). |
| Pieces per outer carton | 20 | ? Number of pieces per outer carton. To order full boxes of the item, please add it to your shopping basket in multiples of this amount. |
| UV filter | Yes | ? 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. |
| Voltage | 12V | ? This may be either a fixed voltage or two values, in which case the product can be used within these limits. |
| Wattage | 50W | ? The power that the bulb consumes. This does not include the loss of any ballast or transformer. |
| EAN code | 4050300428772 | ? EAN code is the barcode of an article which is used worldwide as article code. The EAN code extra is the code from the extra packing. |
| EAN code (extra) | 4050300531861 | ? EAN code is the barcode of an article which is used worldwide as article code. The EAN code extra is the code from the extra packing. |
