SLV Numinos L CL plafond opbouwarmatuur 20W leverbaar in diverse uitvoeringen
| Manufacturer's article number | 1004314 | ? Manufacturer's part number. |
| Appliance class | Class I (earthed) |
?
In the electrical appliance manufacturing industry, the following IEC protection classes are used to differentiate between the protective-earth connection requirements of devices. Class I These appliances must have their chassis connected to electrical earth (ground). This earth conductor is coloured green/yellow in most countries (green in US, Canada and Japan)
Class II These appliances are double insulated. It has been designed is such a way that is does not require a safety connection to electrical earth (ground)
Class III These appliances are designed to be supplied from a separated/safety extra-low voltage (SELV) power source maximum 50V (Volt) AC alternating current. The voltage from a SELV supply is low enough that under normal conditions a person can safely come into contact with it without risk of electrical shock.

| Average life span | 50000h | ? 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. |
| Ballast | LED Converter | ? A conventional ballast has a wound coil. It is somewhat cheaper to buy, but more expensive to run because more power is converted into heat. An electronic ballast not only has a lower power consumption, but it also has the advantage of longer lamp life. |
| Beam angle | 24°, 36°, 60° |
?
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 | SLV | ? If the product is unbranded, we do not have a regular supplier for it. Therefore, the product version may slightly vary. |
| Colour | White, Black | ? Most common colour in the product. |
| Colour code | 930, 940, 927 |
?
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 | >90 |
?
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 | 2700K, 4000K, 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.
|
| Dim to warm | No |
?
Dim to warm is a dimming technique that adjusts colour temperature as the light is dimmed: it shifts from warm white to extra warm white when fully dimmed. This technique has various names, such as Dimtone or Glowdim. |
| Dimmable | Yes, Dali, Pushbutton, C dimmer (Tronic electronic transformer) | ? Some lamps and ballasts are dimmable. There are different types of dimmers and different ways to dim a ballast or transformer. In case of insufficient knowledge, please check with our sales department. |
| Height | 213mm | ? Maximum height in millimetres. |
| Inner ring colour | Black | ? Inner ring colour. |
| Lamp included | Yes | ? Luminaire including or excluding lamp(s). |
| Light source | LED | ? Type of lamp that fits in the luminaire. In some cases, several types of lamps can be used in one luminaire. |
| Luminaire application | Indoor | ? Application of the luminaire depending on the environment. For example, an indoor fitting cannot be used outdoors. An outdoor luminaire, on the other hand, could be used indoors, but may be less suitable here, fore example because it provides too much light or is aesthetically unsuitable. |
| Luminaire type | Ceiling surface mounted | ? Type of luminaire application. |
| Luminous flux | 2340lm, 2400lm, 2430lm, 2440lm, 2475lm, 2620lm, 2675lm, 2715lm | ? The amount of light transmitted by the light source per second. The unit of luminous flux is the lumen (lm). |
| Outside dimensions | Ø100mm | ? Outside Dimension is the largest size, often of the lamp head. |
| Pieces per outer carton | 1 | ? 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. |
| Voltage | 220V-240V | ? This may be either a fixed voltage or two values, in which case the product can be used within these limits. |
| Wattage | 20W | ? The power that the bulb consumes. This does not include the loss of any ballast or transformer. |
