The LED modules can be ordered for 12, 24 Volt or 48 Volt operation or for constant current. 

How much light the lighting emits is critical. Whether light bulb, low-energy lamp or LED module, the luminous flux is stated in lumen for all products. This value includes the light emitted in all directions. With linear LED lighting, the luminosity is better stated in lumen per metre (lm/m).

Apart from the luminous flux (lm), for linear LED lighting the energy consumption is also stated per metre (W/m). If we divide the lumen by the wattage, this gives a very good comparison value for the efficiency of an LED module. Cheap products often have an energy consumption up to five times higher than that of quality products. This is noticed not only in electricity costs, but also in the heat development and therefore the lifespan of the LED modules.

BILTON offers flexible module lengths from 0.3 to 25 metres. This means that modules can be ordered to size as much as possible. IC controls allow module lengths of up to 25 metres without luminosity flux drop. Over long distances, this reduces the number of electricity connections and power supplies at intervals can be omitted.

A high level of separability ensures that cold ends are avoided. Cold ends occur if the distance from the last module to the end is greater than its range as a result of the radiation angle. BILTON offers high separability of up to 2.5 centimetres.

The distances between the individual LED chips is called the pitch. The smaller the distances, the higher the homogeneity in the lighting. The result is perfect lines of light instead of single points of light.

White does not equal white. To distinguish differences, colour temperature is measured in Kelvin (K). The reference in domestic use is the warm-white light of a light bulb (approx. 2,700 to 2,800 Kelvin). The higher the value, the colder the light is perceived. Natural daylight ranges from 3,200 K at sunrise and sunset to 6,500 K at the sun's highest point. “Tunable white” LED strips can imitate this daylight process. Through individual phosphor layers on the LED chips, even the colour of the radiated light can be designed according to customer requirements

The term binning describes the selection process, which LED chip manufacturers use to categorise LEDs, particularly in respect of the colour location. As the human eye tolerates colour deviations very differently depending on the colour, the so-called MacAdam ellipses are used for classification. They represent elliptical colour spaces, in which we do not yet perceive deviations from the reference. A 1-MacAdam ellipse stands for no discernible deviation. Deviations up to stage 3 are “barely perceptible”. LED chips in the tolerance of a 7-times MacAdam ellipse lead to inhomogeneous colour representation in LED modules

It is not only the light colour that is important. It is also important that objects appear in their genuine colours. The colour representation index CRI is a dimensionless figure, which reflects the quality of a light source. It judges the similarity of the spectrum of an LED chip to a reference spectrum. By definition “100” is the highest value, there is no bottom limit. Colours are well represented if the colour representation index has a value above 80 Ra. In housing and working lighting, the CRI should be more than 80 Ra, if several light colours are used at the same
time, it should be 90.

Depending on the application, a different radiation angle for the lighting is critical. The higher the radiation angle, the more area is illuminated. LED modules have a radiation angle of up to 120 degrees. As a result, the light is significantly more directed and compared to T5 fluorescent tubes there is less loss through reflection.

Unfortunately, some module manufacturers use the possibility to increase the brightness of LED chips “artificially” by operating the LEDs with higher currents. However, this leads to serious negative impacts on lifespan and energy efficiency. The LM80-08 standard is the requirement for a standardised testing process to determine the lifespan of LED modules. The lifespan is stated in operating hours. The lifespans of the BILTON LED modules are measured according to LM80-08. After 60,000 hours, they still provide 80 % of the original luminous flux.

Protection against environmental influences is one of the most important criteria for the longevity of LED modules. Depending on the application case, LED modules need different protection classes. The higher the protection class IP, the more important the quality of the coating. As a result of the BILTON CVD coating, protection class IP66 (protection against dust and spray water) can be achieved without colour location shift.

From an order quantity of 20,000 running metre, individual branding, so-called “private label” is also possible. As additional proof of your own brand quality or as specific trademarks.
