| Manufacturer's article number | 4058075822399 | ? Manufacturer's part number. |
| Manufacturer's article number (old) | 822399 | ? Manufacturer's part number. |
| Application directly to the mains | Yes | ? These lamps can be applied directly to mains voltage 230V AC (alternating current) |
| Application to conventional ballast EM | No | ? These lamps can be applied on a conventional ballast (wounded coil, choke or magnetic ballast). |
| Application to electronic ballast EB | Yes | ? These lamps can be applied with an electronic ballast (EVSA or HF ballast). Consult the manufacturer's compatibility lists to check whether the combination is compatible. |
| Application to LED driver | No | ? These lamps can be applied to an LED driver. Please note the manufacturer's specifications for the correct current value. |
| Average life span | 30000h | ? 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 | 120° |
?
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 | Ledvance | ? If the product is unbranded, we do not have a regular supplier for it. Therefore, the product version may slightly vary. |
| Colour code | 840 |
?
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 | 4000K |
?
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.
|
| Diameter | 45mm | ? Diameter in millimetres, measured at the widest point. |
| 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 | No | ? 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. |
| Eprel registration number | 1404797 | ? Eprel (European Product Registry for Energy Labelling) registration number. |
| Lamp base | GX24q-4 (4-pins) | ? Cap, lamp holder or lamp base type. |
| Length | 164,8mm |
?
Product length in millimetres. For fluorescent tubes, this excludes the metal pins on the end unless otherwise stated. |
| Luminous flux | 2250lm | ? The amount of light transmitted by the light source per second. The unit of luminous flux is the lumen (lm). |
| Number of switch cycles | 200000 | ? The life span of a lamp may be limited by the number of switch cycles, which is the number of times a lamp can be switched on and off before it becomes defective. |
| Pieces per outer carton | 10 | ? 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. |
| Power factor | >0,9 | ? Power factor is the ratio between net power and apparent power. The PF is the value that indicates how efficiently electrical power is delivered to the consumer. Ideally, the PF is equal to 1. Anything below 1 means that additional power is required to deliver the desired power to the consumer. |
| Wattage | 20W | ? The power that the bulb consumes. This does not include the loss of any ballast or transformer. |
| Wattage equivalent | 42W | ? Replacement bulb power specified by the manufacturer. A CFL and LED display average 5x as much light compared to a standard bulb. To the CFL or LED power available divide the bulb power by 5. |
| EAN code | 4058075822399 | ? 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) | 4058075822405 | ? 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. |
