LED, lumen, and light pattern

NORDLYS High Beam 431130

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.

NORDLYS Light pattern

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.
