We deliver to installers and end users. We do not deliver to individuals.
(LED) light systems by Veko are applied in manufacturing areas, (high-bay) warehouses, distribution centres, multi-storey car parks, sports facilities, swimming pools and shopping malls.
Veko has produced its line lighting in its own manufacturing facility in Schagen, the Netherlands, for over 40 years. In addition, we have a product development test room, SMD production room and showroom at our own premises.
Yes, we are happy to show you around our Schagen premises. School classes and students are welcome too. You can email your request for an appointment.
Fluorescent lighting is not a sustainable product and is not energy efficient. We advise our customers against using fluorescent lighting in their lighting systems. If you are still using fluorescent lighting, we recommend system renovation. The investment in LED quickly pays for itself. And if you are already using Veko lighting, all you need to do is switch the luminaire from fluorescent to LED. If you opt to install another brand in our light line, your warranty will be voided, and you will not be insured if damage occurs that is caused by your lighting.
Yes, absolutely. This is a perfect solution for rented buildings in which you still require the best possible lighting. During the rental period, you always have the option to purchase the lighting at a favourable charge. Ask your Account Manager about the possibilities.
By default, Veko supplies all LED luminaires with a unique replacement warranty of 5 years or 25,000 operational hours. Furthermore, Veko applies a 1-year warranty to batteries of decentralized emergency lighting, and a 2-year warranty to all other products.
In case Veko has installed the lighting, we will check it between 200 operational hours and 1 year after delivery once and repair any defects.
A detailed description of the warranty terms of Veko Lightsystems International can be found in article 17 of our general terms and conditions. For local sales within the UK, article 15 of the general terms and conditions of Veko Lightsystems Ltd is applicable.
In some cases, we can even provide 10 years warranty on LED fixtures. More information about this can be provided upon request. The full guarantee plan can be obtained from Veko.

LEDs are Light Emitting Diodes: electronic components that convert electrical energy directly into light through the movement of electrons inside the diode material. LEDs are important because, due to their efficiency and low power consumption, they have become a substitute for most conventional light sources.
The lumen per watt (lm/W) ratio indicates the efficiency of a lamp. The higher this value, the less power is required to produce a certain amount of light. Please note if this value is determined for the light source or luminaire as a whole or for the LEDs used in it. LEDs themselves have a higher value. There is always some loss in efficiency, for example when drivers and optics are applied. This is the reason why LEDs may have an output of 180lm/W, while output for the luminaire as a whole is 140lm/W. Manufacturers are required to state the value of the light source or the luminaire. The output of the luminaire has priority over the light source output, because LED luminaires are assessed as a whole.
The power factor indicates the relationship between the power input and the power used to enable the LED to function. There is still a loss in LED chips and drivers. For example, a 100W LED lamp has a PF of 0.95. In this case, the driver requires 5W to function, which means 95W LED power and 5W driver power.
Demagnetising a coil and charging the capacitors is referred to as apparent power. This power is not included in the driver or the LED but is returned through the reference line. This is what we call blind current, and it is important to take it into account when renovating. This is especially true of older buildings where the nylon wire may be thinner, which can lead to short circuit (and thus to fire) in the case of excessive blind current. Blind current is a common problem especially with LED tubes, because the existing magnetic ballast often remains. This was developed for fluorescence (TL) and not for LED.
DIALux is a drawing program for all light calculations that are required for a light design, in order to provide substantiated advice to the end user. Always have a DIALux design produced by a certified DIALux designer, such as Veko Lightsystems International BV. These certificates are issued by DIALux after successful completion of a course. The certification guarantees that the design completely matches the real-time situation and avoids any unpleasant surprises.
The CRI or Colour Rendering Index is an index for determining how natural colours are displayed by the light of a lamp, with a reference value for a halogen or incandescent lamp.
The colour temperature of a light source is expressed in Kelvin (K). Warm white is 2,700 K and daylight around the 6,500 K.
A light module is the LED pendant of a conventional lamp. It usually consists of an LED chip that is mounted on a circuit board equipped with electrical and mechanical attachment materials. This means that it is ready to be attached to the luminaire. Note: the light module may consist of more than one chip and can be a composition of 9 or 16 chips, sometimes with a phosphor coating.
The Surface Mounted Device (SMD) LED is 1 LED on a circuit board, which can be in mid-power or low power and is less sensitive to heat generation than a COB (Chips On Board) LED. SMD LEDs are usually mounted on a Printed Service Board (PCB), a circuit board onto which the LEDs are soldered mechanically. When a small number of LEDs with relatively high power are used, the heat distribution on this PCB is unfavourable. It is better to use a mid-power LED in that case, because the heat is then better divided between the LED and the circuit board. The circuit board must consequently also lose heat. This is achieved by placing the PCB on an aluminium profile. High-quality LED lighting products have an aluminium profile on the outside in order for the ambient temperature to cool the lamp. Cheaper variants are equipped with a plastic casing, since plastic is cheaper than aluminium. These products only offer good heat dissipation from the LED to the base plate. If the aluminium does not lose this heat, cooling remains problematic.
Retrofitting means: replacing a conventional light source with LEDs while retaining the luminaire. In this case, only the light source is replaced, possibly with some adjustments to the luminaire. Although some refer to this as renovation, the base remains the same.
UGR stands for Unified Glare Rating, or the glare value for a light source. This is a calculated value for the degree of luminaire blinding and is valuable for assessing comfort.
Standard Deviation Colour Matching (SDMC) is a measuring unit of colour difference between different products in lighting. Colour tolerance is expressed in different Mac-Adam steps.
DALI stands for Digital Addressable Lighting Interface and is applied in light management. In a network or stand-alone solution, each fitting is allocated its own address. This allows each lamp to be individually accessible and controlled (on – off - dimming). DALI consists of a 2-wire drive which runs apart from the power supply and can be expanded with motion and light sensors among other things.
Alongside LED chips, drivers are an important part of LED lighting. It is important that these two components are matched to each other. Roughly 60% of all warranty cases based on failure are caused by a driver failure rather than by the LEDs.
The LB standard is increasingly mentioned in lamp specifications. This gives a good indication of quality, both in terms of light recovery and LED failure. The ‘L’ value indicates the amount of light recovery after a lifetime. An L70 after 30,000 operational hours indicates that after 30,000 functional hours, 70% of the light remains. An L90 after 50,000 hours indicates that after 50,000 operational hours, 90% of the light is left, thus signalling much higher quality. The ‘B’ value is also important. This relates to the percentage that may deviate from the L value. This may for instance be due to the failure of LEDs. L70B50 after 30,000 hours is a very common specification. It indicates that after 30,000 operational hours, 70% of the new light value is left, and that a maximum of 50% deviate from this. The B value is based on a worst-case scenario. If the B value is not mentioned, B50 is used. Veko luminaires are rated L85B10, which indicates the high quality of our luminaires.
Increasingly, light sources are being expressed in the unit Lumen. Light sources were formerly measured by ‘Wattage’. In traditional lighting, the ratio between Lumen and Watt was equal, and not bound to a brand or kind of lamp. Lumen is the light intensity that a light source emits, and is not visible. The radiation that comes from a lamp until it touches a surface, such as a work floor, is called light intensity, and it is displayed in Candela.
The amount of light reaching the floor (or desk) is measured in Lumen per m2, i.e. Lux (1 Lux = 1 Lumen per m2). The illumination intensity is measured with a Lux meter.
Luminance is the radiation of the work floor to our eyes, the unit is Candela per m2. This is measured with a spectrometer and/or luminance meter.
Although the initial cost of conventional light sources is lower than that of LEDs, the operational costs of LEDs are significantly lower. LEDs have a longer lifespan and lower maintenance and replacement costs. Since LEDs need to be replaced less often, the owner spends less money on new lamps and labour costs needed to replace them. Furthermore, LEDs consume less energy. As a result, the total cost of a LED system can be significantly lower than that of conventional lighting systems.
Most lighting applications with LED are paid back in only three to four years. LED Light systems by Veko are generally paid back in one to five years.
The term solid state illumination is used because the electronics produce the light directly from the solid materials in which the electrons are incorporated. This differs from other technologies, such as fluorescence technology which requires a gas discharge medium to initiate the production of light.
In order to properly detect colour, both the spectral composition and the amount of light are important. Colour consists of three basic colours: red, green and blue. A mix of these colours can create all colours that exist, except for black. Therefore, black is not a colour. When we mix green, blue and red light, we get white. However, when we mix matter (such as paint) in red, green and blue, we get black. In the dark, colours are perceived poorly. The human eye will then adapt (adaptation) to sufficient visibility in the dark. We can then better distinguish details and our perception is in grey tones. The complete adjustment process from light to dark takes about half an hour. The adaptation from dark to light takes only about a minute. During the daytime and with sufficient light (from about 500Lux) colours are noticeable.
A lighting plan is an important part of both new construction projects and renovation projects. With a DIALux plan, a thorough lighting plan is made based on facts rather than estimates. In large projects, it is also recommended that a performance test be conducted in accordance with the NEN: 1891. This checks whether the delivered installation complies with the design that was made. The largest risk for LED lighting is light recovery, which is only detectable when measured after delivery.
The driver is the determining factor of how dimmable a lamp or luminaire is, and in what way this should be done. For example, drivers can work with DALI, 0-10V or TRIAC (phase cut). Whenever it is possible to dim LED lights, this is always preferable. If the LED can be dimmed by 30%, it can increase savings by 30%, as well as extend the lifespan of the light. Dimming can be done manually, for example, with integrated dimmers, or automatically with a system such as DALI. A DALI system automatically adjusts the dim level of illumination based on the amount of daylight in a room. This is done by placing a sensor with a control device in the room. This additional cost is usually returned within a very short time based on energy savings.
Motion detectors or presence sensors are an excellent combination to be used with LED lighting, because they can directly turn on and off. This type of lighting is ideal in a hall, or a toilet, but it can also be used in a variety of industrial spaces and warehouses where people are working. Most LED lights are tested to survive 1,000,000 switching times, which is good for years of use. One tip: it is preferable to apply a motion detector separate from the luminaire, since the light source is likely to last longer than the sensor. Moreover, a defective sensor can prevent additional cost savings.
Light bulbs and halogen lamps are known to lose up to 95% of energy in the form of heat. Many people think that no heat is released with LED lamps, but the opposite is true. LED lamps also generates heat, about 50 to 70% of the energy is converted into heat. In order to ensure the quality and lifespan of the LED, this heat must be discharged via a base plate (PCB) and through an efficient heat conductor such as aluminium. The efficiency of a LED lamp is determined by the extent to which the absorbed power is converted into as much light as possible and as little heat as possible. The more light we get out of a LED lamp, the higher will be the Lumen/Watt ratio. So, a high lm/w ratio LED lamp produces less heat than a lower lm/w LED lamp.
LED lighting must be able to emit heat both in the base and in the luminaire. This requires proper cooling. If the cooling is insufficient, then there will be a higher relapse of light. First of all, cooling is required where the LED is attached to the base plate. The base plate can be either a PCB or an aluminium (metal-core) PCB. What is important is how well this base plate can emit heat to the environment or the luminaire. Veko mounts the LEDs directly on the aluminium PCB, which provides significantly better cooling results.
LEDs have a focused beam of light, unlike traditional luminaires that spreads light on its surroundings. When LED luminaires are provided with reflectors, much of the light in the centre of the beam leaves the system without even coming into contact with the reflector. This reduces the degree of modulation of the light beam and can be the cause of blinding. Lenses help to guide almost any beam of light emitted by the LED.
The operating temperature is a major influence on the lifespan of LEDs. The recommended operating temperature depends on the selected cooling, driver, LEDs and housing. A unit must be judged as a whole, rather than its components separately. After all, the ‘weakest link’ can be the determinant. Low temperature environments are ideal for LEDs. Cooling and freezing cells are particularly suitable, because the LEDs can get rid of the heat well. Since less heat is already generated with LED than with conventional lighting, cooling will also need less power to maintain its temperature. A win-win situation! In relatively warm environments, the situation becomes different. Most LED lighting has a maximum operating temperature of 35° Celsius, Veko lighting goes up to 45°C!
LEDs can be powered by amps (in mA) or voltage (Volts, or V). Most consumer lights are powered by voltage, primarily 12V and 24V. However, when the power has to bridge a longer distance, a loss in voltage can occur. That is why industrial LED systems are powered by amps, usually 350mA, 700mA or 900 mA. The flow rate then depends on the load and can vary between 20V and 50V.
With daylight control, the biological clock can be controlled, by adjusting light intensity and -colour to the time of the day. This is widely used in hospitals (shift services), but it is also becoming increasingly common in schools and industries. The application of daylight control is very interesting, since light becomes an instrument used to improve individual performance. In the morning, for instance, melatonin is still present in the body. By using neutral light with a high intensity, it can help to breakdown this hormone in the body allowing better concentration. In the afternoon dip, the intensity of light can be increased again and the colour adjusted to daylight so productivity can also be increased.
LEDs do not contain gasses, glow spirals or moving parts that are exposed to exhaustion. They produce light through a one-step process that takes place inside the diode. Moreover, there is no glass that can break or screwed contacts that might get loose.
