? Either show items that are in stock or items that are not in stock.

? 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.

? If the product is unbranded, we do not have a regular supplier for it. Therefore, the product version may slightly vary.

? 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

? 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 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.

? Number of hours after which 10% of the lamps have been interrupted when using a conventional (wound with copper wire, not electronic) ballast.

? Number of hours after which 50% of the lamps have been interrupted when using a conventional (wound with copper wire, not electronic) ballast.

? Diameter in millimetres, measured at the widest point.

? 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.

? Number of hours with 10% of the lamps has been interrupted by application of an electronic (or HF) ballast.

? For many applications, there are special lamps. Maybe your application there and there is a more suitable lamp available.

? Product length in millimetres. For fluorescent tubes, this excludes the metal pins on the end unless otherwise stated.

? The amount of light transmitted by the light source per second. The unit of luminous flux is the lumen (lm).

? 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.

? 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.

? The power that the bulb consumes. This does not include the loss of any ballast or transformer.
