Ledvance LED Tube Performance Class T8 External 15W 830 3000K 1200mm 35

Manufacturer's article number	4099854015281	? Manufacturer's part number.
Application directly to the mains	No	? 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	No	? 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	Yes	? These lamps can be applied to an LED driver. Please note the manufacturer's specifications for the correct current value.
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	Exclusive	? 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	190°	? 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.
Built-in motion detector	No	? Luminaire or lamp has a built-in motion detector. The light will switch on when a movement is detected.
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 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.
Constant current	350mA	? For constant current drive LED's are connected in series. The driver must be able to provide the appropriate current.
Diameter	27mm	? 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	Yes	? 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	1278963	? Eprel (European Product Registry for Energy Labelling) registration number.
Lamp base	G13	? Cap, lamp holder or lamp base type.
Length	1200mm	? Product length in millimetres. For fluorescent tubes, this excludes the metal pins on the end unless otherwise stated.
Luminous flux	2160lm	? 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	25	? 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.
Protective sleeve	Yes	? Equipped with plastic coating, which holds together the lamp components and glass in the event of breakage. Suitable for the HCCP and ISO 22000 standard. Applied to places where lamp rupture may cause damage to products or processes. The coating has a lower UV radiation.
Temperature range	-20° to 50° C	? If applied outside the specified temperature range, the components will not function properly.
Wattage	15W	? The power that the bulb consumes. This does not include the loss of any ballast or transformer.
EAN code	4099854015281	? 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)	4099854015298	? 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.
