GUIDES
At NORDLYS® we thrive to enlighten. Not just dark roads, but our customers too. We want every customer to understand their own needs and help them make the right choice of light. This is why we’ve dedicated a whole section on our site to learning. Here you’ll find explanations on technical terms, product series and much more. If you feel you need further assistance, please don’t hesitate to contact us. We are ready to guide you and answer any questions you might have.
Standard or NORDLYS+
Every NORDLYS® light is carefully selected and tested to ensure highest quality and functionallity.
Generally our lights are put into two series. The Standard series and the Plus series.
Compare the two series below and see which part of the NORDLYS® family that suits you best.
The standard model, which includes many of our lights and electrical components, are great lights at an acceptable price with great standards and needs.
All of the lights are LED lights with a long life of 50.000 hours, and at the same time has a low power consumption.
The lights have an IP-rating of 67 or 68.
An IP-rating is the degree of protection against dust and water penetration. More information on IP-ratings.
Furthermore, they meet the criteria of being environmentally friendly, and more important the standard model has a 2 years guarantee.
The plus model, which includes many different lights, are lights that meet and exeed our standards and criteria.
The lights are of exceptional design and high quality.
The plus lights have an extra high lumen rating.
All of the lights are LED lights with the same long life of 50.000 hours as the standard series and at the same time has a low power comsumption.
Difference is that the plus series lights are top of the line.
The lights have an IP-rating of 69K. The highest rating possible. More information on IP-ratings.
They also have a bi-polarity protection and they meet the criteria of being environmentally friendly, and more important the plus model has a 5 years guarantee.
LED, lumen and light pattern
Choosing Led light bar and Led work light
LED: (Light Emitting Diode) is a replacement for traditional light sources such as incandescent lamps and halogen. LED reduces power consumption by about 80% compared to halogen. When choosing the working lamp, it is not only the lumen number that must be decisive.
A high lumen value might not be the same as proper lighting. The value in “lumen” indicates only how bright a light source (e.g., THE LED) radiates. Manufacturers’ challenge is to collect the light beams, collect them, and throw them to the ground in the desired work area.
When choosing a suitable LED work light, do not just look at the datasheets’ lumen entries. Many manufacturers indicate only the calculated lumen quantity, which may differ enormously from the actual measured lumen number. Therefore, always check the light indications “measured lumen” before choosing a LED light.
Theoretical lumen is a calculated value of the number of the lumen.
Effective lumen is the number of lumens measured outside the glass. An H3 55W bulb has approximately 1000-1200 theoretical lumen and 700-800 effective lumen.
Watt is the power consumption of the lamp.
IP Rating: Degree of protection against dust and water penetration. The maximum value is IP69K.
EMC R10: Protected from emitting and receiving electromagnetic noise.
ECE R23: Meets the requirements for reversing lights concerning the angle of light to the roadway.
Light pattern
Flood spreads the light. Use where it is vital to have a wide range of lights, e.g., work lights.
Spot gathers the light. Use when it is crucial to light long and concentrated, e.g., floodlights.
Combo is a combination of Flood and Spot. Use for long-distance headlamps.
Scene spreads desires more than Flood. Use for nearby areas.
IP-rating explained
Let’s get tecnical…
What does IP density mean?
IP stands for International Protection. IP density follows DIN 40 050, Part 9 standard. The purpose of this standard is an accurate definition of the rules for penetration of solid foreign objects, including dust and water in electrical equipment on vehicles.
Density IP 5K4K
Dust must only enter in such a quantity that the function and safety are not affected. Water, which, with increased pressure, sprays against the housing from all directions, must not have any harmful effects; water pressure approx. 4 bar.
Density IP 9K
Water, directed at the house with a high pressure/steam jet cleaner, must not have any harmful effects; water pressure approx. 80-100 bar.
Density IP 6K7
Do not allow dust to enter. Even in the case of temporary submersion, water must not enter.
IP ratings explained
First Digit (intrusion protection)
0 – No superior protection. It was not rated (or no rating supplied) for protection against the ingress of this type.
1 – Protection from a large part of the body, such as a hand (but no protection from deliberate access), from solid objects greater than 50mm in diameter.
2 – Protection against fingers or other objects not greater than 80mm in length and 12mm in diameter (accidental finger contact).
3 – Protection from entry by tools, wires, etc., with a 2.5 mm diameter or more.
4 – Protection against solid objects larger than 1mm (wires, nails, screws, larger insects, and other potentially invasive small items such as tools/small, etc.).
5 – Partial protection against dust that may harm equipment.
6 – Dust-tight. Full protection against dust and other particulates, including a vacuum seal, tested against continuous airflow.
Second Digit (moisture protection)
0 – No protection.
1 – Protection against vertically falling droplets, such as condensation. The protection ensures that no damage or interrupted functioning of components will be incurred when an item is upright.
2 – Protection against water droplets deflected up to 15° from vertical
3 – Protected against spray up to 60° from vertical.
4 – Protected against water splashes from all directions. Tested for a minimum of 10 minutes with an oscillating spray (limited ingress permitted with no harmful effects).
5 – Protection against low-pressure jets (6.3 mm) of directed water from any angle (limited ingress permitted with no harmful effects).
6 – Protection against direct high-pressure jets.
7 – Protection against full immersion for up to 30 minutes at depths between 15 cm and 1 meter (limited ingress permitted with no harmful effects).
8 – Protection against extended immersion under higher pressure (i.e., greater depths). This test’s Precise parameters will be set and advertised by the manufacturer and may include additional factors such as temperature fluctuations and flow rates, depending on equipment type.
9 – (K): Protection against high-pressure, high-temperature jet sprays, wash-downs, or steam-cleaning procedures – this rating is most often seen in specific road vehicle applications (standard ISO 20653:2013 Road Vehicles – Degrees of protection).
Approvals explained
ECE R 65
Defines the light values to be achieved, the distribution of light, and the marking lamps’ color position. Only warning lights complying with ECE-R65 may be used in public transport.
ECE R48 reef. 6
Notice requiring all side marker lamps to flash simultaneously with the vehicle’s flashing lights.
EMC
Approved and granted electromagnetic proficiency.
If the lamp is not designed to the EMC specifications, and no certification is available, there may be interference with other electronic safety-relevant systems.
Example: Noise in the radio speakers, failure of the ABS electronics, or damage of the lamp due to noise sensitivity.
