FAQ - NORDIC LIGHTS® - Nordic Lights Ltd.


Our lamps are proven to perform reliably in the most demanding of environments all over the world! This is reflected by our continuously high supplier quality ratings, customer feedback, repeat business, & very low customer returns.

Our comprehensive warranty provides peace of mind that your lamps will continue working for many years without issues.

We are an approved & preferred supplier to many of the world´s leading manufacturers of heavy duty machinery.

We only use the highest quality components from the most reputable & approved suppliers.

Our extensive state-of-the-art in-house testing laboratory ensures we can continually & repeatedly confirm the quality, reliability & performance of our designs.

Every production lamp is functionally checked and operationally tested for over 10-hours prior to being shipped.

We outperform our competitors by applying the latest & best available technology along with outstanding customer service provided by our well trained, experienced & dedicated personnel.

Our team has extensive combined knowledge & experience, not only from all areas of the lighting industry (from light sources & lamps through to optics, electronics & control systems), but also from the industries where our lamps are intended for use. This ensures we really know & understand the requirements for light in all its applications. We can help you in a vast range of topics: simulation (light and 3D modelling), optimal positioning of lamp on vehicle, standardizing how much light is needed in different areas, recommend suitable lights, customize lights, studying the vehicle in the terrain, comprehensive testing facilities, as well as with knowledge of regulations.

We can offer tailor-made solutions to ensure you get the best product for your application. Combinations of different light patterns, brackets, vibration dampeners & cable connections can be applied to optimize a lamp for different applications & a specific set of conditions.

Our processes are approved to ISO9001, ISO14001 & we utilise six-sigma & Lean methodologies.

Colour Temperature refers to an ideal black body radiator. Correlated Colour Temperature refers to a light source whose perceived colour most closely resembles that of a black body radiator. Correlated Colour Temperature (CTT) describes if the appearance of white light is warm (reddish), neutral or cool (bluish). It is expressed in Kelvin (K). Higher values relate to cooler colours.

IP means “Ingress Protection” or “International Protection”. The IP code is defined in standards IEC 60529&DIN 40050. It classifies the degree of protection provided by an electrical equipment enclosure against the intrusion of solid objects & liquids.

There are many different definitions for this. In general, “intelligent” or “smart” lighting can be seen as lighting which will either automatically adapt its intensity in some way without the need for any user input, or automatically gather or transmit additional data to other applications. Both solutions require that the lighting is integrated with additional sensors.

Improved visibility due to “cooler” light colour.

More energy efficient compared to halogen.

High light output & wide illumination area.

HID bulbs are standardized.

Less heat generation compared to halogen.

Longer service life than halogen.

Easy to replace.

Energy efficient low power consumption (- 85% compared to other light sources).

Compact & directional providing design flexibility & no wasted light.

Unaffected by switching cycles.

Natural colour temperature (“Daylight”) which is easier on the eyes & results in better, more productive working conditions.

Very long lifetime compared to other light sources (50,000+ hours).

Maintenance free. No bulb replacement results in less machine down time & lower maintenance costs.

Rugged. No vulnerable filament. Lamps can take extreme abuse.

Starts instantly (Nanoseconds versus minutes – HID).

Environmentally sound. No hazardous substances (lead/mercury).

RoHS complaint.

Very wide operational temperature range.

Halogen = 500 hours

HID (Xenon) = 5,000 hours.

LED = 50,000 hours.

Yes. As long as the lamp in question has more than one LED chip. The light output will of course be reduced.

Yes. The Spica & KL ranges have isolated electronics. Also the Scorpius N4410 has electronics that are isolated from the lamp casing.

Yes. Polarity must be observed for correct operation. The “+” & ”-“ connections are marked on the lamp.

Lamps are reverse polarity protected to -32VDC.

Lamps are over-voltage protected up to 80VDC.

Low heat generation is a common misconception about LED’s. Any electrical component consuming energy produces heat in some form.

With LED’s the heat is generated at the base of the LED chip (the LED “junction”) & is directed backwards from the light emitting surface. This is why the lenses of LED lamps are significantly cooler than those of halogen or HID solutions which direct the majority of their heat forwards.

The temperature of the LED junction is absolutely critical to achieve the optimum lifetime of the LED. Poor LED thermal management will result in dramatic reductions of LED lifetime. Effective cooling of the LED chips is required & achieved by careful design of the metal heatsink (the lamp casing). As heat is dissipated through the casing, the case naturally heats up.

Yes, but optimal lamp cooling is achieved if the heatsink fins are vertical rather than horizontal. It should also be noted that, depending on the lens used, there may be differences in light distribution if a lamp is rotated.

Yes. Various combinations of LED lamp lumen output & light pattern are available. The correct replacement LED lamp to choose will depend on the application.

It should be remembered that LED typically has a higher colour temperature than HID. The lamps are more efficient & light is much more directional, resulting in less stray (wasted) light & illumination more accurately directed to the area where it is really required.

No. The lamps are designed to take the brand bridge into account. The LED’s are positioned higher & lower than the bridge &, combined with the light guides & lens designs, ensure that the usable light is directed where needed so that the resulting light pattern is exactly as intended.

Due to the low power consumption of the Dorado indicator LED, some vehicles may require an additional electrical load to ensure the circuit functions correctly. The “tell-tale” is the additional load required by the vehicles system and is included in the lamp assembly.

The lamp production date is located on the product label.

The Beam angle is the angle between the two planes of light where the luminous intensity is 50% of the maximum luminous intensity at the centre of the beam.

The Field angle is the angle between the two planes of light where the luminous intensity is 10% of the maximum luminous intensity at the centre of the beam.
