What is a Good CRI Rating for LED Lights?

The Color Rendering Index (CRI) is a critical measure of how accurately a light source reveals the colors of objects compared to a natural light source. For LED work lights used in demanding industries such as mining, construction, agriculture, forestry, and material handling, a good CRI rating is essential for ensuring safety and efficiency.

Does the “brand bridge” across the centre of the Nordic Lights LED lamp lenses have any effect on the light pattern?

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.

Can an LED lamp replace an HID lamp?

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...

Do you have LED lamps where the electronics is fully isolated from the case?

Yes. The KL range has isolated electronics. Also the Scorpius N4410 has electronics that are isolated from the lamp casing.

Does the LED lamp still work if one of the LED chips fails?

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

What are some benefits of LED?

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...

Why do you have so many different types of LED work lights?

An LED is not a standardized light source like a halogen or HID bulb. LED’s vary, particularly in physical size & lumen output. This enables flexibility to produce lamp designs suitable for a wide variety of applications & customer requirements. A lamp with lower lumen output typically requires less, or lower powered LED’s than a lamp with a much higher output. The lamps physical dimensions,...

What can make LED’s flicker, or appear to flicker?

Lamps using switched power supplies actually turn the LED’s on and off extremely rapidly (<300Hz). However, the human eye cannot see this (the eye can only see flicker below about 200Hz). If LED flickering is noticeable then there could be various reasons: Cheap LED lamps may be designed with too low LED switching frequency. There may be a fault in the lamp circuitry. There may...

What’s the difference between Theoretical & Operational lumens?

A Lumen is the unit of measurement of the complete quantity of light emitted by a light source – the luminous flux. Lux is the quantity of luminous flux on a surface. It decreases by the square of the distance (inverse square law) of the surface from the light source: E(lx) = luminous flux (lm) / area (m2). What is the difference between a Lumen...
