FAQ Page
What does “lm” stand for?

“lm” is an abbreviation for “Lumen”. It is also often referred to as “Output”. Lumen is a measurement of the luminous power emitted by a light source. This unit is often confused with “Lux” – see here. Our products range from 40 up to 5,000 lumens

What is IK?

“IK” is an abbreviation for “Impact Resistance (Kinetic Energy)”. This unit indicates the degree to which an electrical device is able to resist external mechanical impacts. Our products are typically rated IK07/IK08 (standard for the industry).

What is K?

K” is an abbreviation for “Kelvin”. It is also often referred to as “Color Temperature”. “K” is a measurement of the color impression of the light, which is often described as warm (low K value) or cold (high K value). The normal range of light is 1700-9500K. Our products are typically in the range of 5500-7500K (standard for the industry).

What is IP?

“IP” is an abbreviation for “Ingress Protection”. It is also often referred to as the “Enclosure Class”. The Enclosure Class is indicated by the letters IP, followed by 2 digits or 1 digit and 1 “x” before or after the digit. This classification indicates the degree to which an electrical device is able to resist the intrusion of solid objects and water/fluid. Our products are typically in the range of IP20-IP67.

What is Ra?

Ra” is also often referred to as “CRI”. See CRI below

What is LED?

“LED” is an abbreviation for “Light Emitting Diode”. It is an electrical component that converts electrical energy into infrared, visible or near-UV light. LEDs are now the primary light source in work lamps, as they can provide high lumen output and are incredibly energy efficient, environmentally friendly, durable and long-lasting – they can emit light continuously for years without “burning out”. On average, the light emitting diode will emit only half as much light after a minimum of 50,000 lighting hours, depending on factors such as high/low temperatures or high electrical loads. We only use “CREE”, “COB” or “SMD”.

What is CREE?

CREE is a brand produced by a company based in the state of North Carolina. They are widely recognized in our industry as the best manufacturer of high-quality LEDs. We use “LEDs” – see here – from CREE in more than 80% of our lights.

What is COB?

“COB” is an abbreviation for “Chip On Board”. It is a type of “LED” where the integrated circuit is directly connected to a “printed circuit board”. By eliminating the link between individual semiconductors, the finished product can be more compact and cheaper, with a higher lumen output. This technology is often called third-generation LED. We use COB LED in approximately 70% of our lamps

What is SMD?

“SMD” is an abbreviation for “Surface-Mount Device”. It is a type of “LED” where the components are attached directly to the surface of a “printed circuit board”. In comparison to “COB”, high lumen (lm) output requires more room for the diodes. Comparison: Task Lamp TL5000 uses 120 x SMD for an output of 5000 lm, while Task Lamp X4 uses just 1 x COB for an output of 3800 lm. SMDs emit less heat, however, so they can be installed in plastic enclosures rather than aluminum or metal. This technology is often called second-generation LED. We use SMD LED in approximately 30% of our lamps.

What is CLASS?

“CLASS” is also often called “Enclosure Class”. It indicates the protection class in relation to the risk of electrical shock. The strictest standards apply for CLASS 0, I, 0I. The standards are not as strict for CLASS II, III. Our products are all CLASS (II) (cabled lamps and power supplies) or CLASS III (battery-powered lamps/lights).

What is enclosure and protection class?

This is typically defined as “IP” or “CLASS”

What is lx?

“lx” is an abbreviation for “Lux”. Lighting power is measured according to how much light impacts a surface. The unit Lux indicates lumens per square meter. This unit is often confused with “Lumen (lm)”

What is CRI?

“CRI” is an abbreviation for “Color Rendering Index”. It is often referred to as ”Ra” (which comes from CIE Ra - the international standard for color reproduction). It indicates a light source’s ability to reproduce colors correctly on a scale from 0 to 100, where 100 is best (daylight). Our products typically have an Ra value of approximately CRI80 (standard for the industry).

What is cd?

“cd” is an abbreviation for “Candela”. It indicates how must light is emitted from a light source in one specific direction. This unit is often used instead of luminous power (“lm / Lumen”) for reflector lamps in order to calculate the lighting power from the lamp at a given distance. We use Lumen (standard for the industry).

Drop test

Our products are tested, including a drop test from a height of 1 meter. The “printed circuit boards” and “LEDs” we use are also subjected to rigorous testing. As with all electrical components, however, they are sensitive to human error (e.g. faulty soldering). Therefore, malfunctions can occur since we produce more than 200,000 units annually.

What is a printed circuit board?

Printed circuit boards are often just called PCBs. They are used in electrical devices to provide an electrical circuit in a compact and durable form.

What is CE?

“CE” is an abbreviation of “Conformité Européenne ”. This label on a product serves as a “travel visa” ensuring the product freedom of movement within the EU internal market. This label is the manufacturer’s guarantee of compliance with all safety directives. The label does not necessarily indicate anything else about the qualities of the product. All of our products meet the requirements for CE labeling.

What is WEEE?

“WEEE” is an abbreviation of “Waste Electrical and Electronic Equipment”. Products bearing the “trash can label” must be disposed of as electronic waste by consumers and manufacturers/importers. We are a member of the Danish Lighting Industry’s WEEE Association, a collective program for manufacturers/importers of light sources that ensures we comply with all statutory requirements.

What type of power charger should I use for rechargeable batteries?

Our products with rechargeable batteries are always supplied with either a power supply and USB cable or just a USB cable. One end of the cable either has a Micro B or Standard Type C connector, which is inserted into the lamp/light. The other end of the cable (Standard Type A connector – 5V DC) is inserted into a power supply, which we recommend as having 3.7V-max. 1A output (such as our CHG011).

When is a defect claim rejected?

Generally speaking, a defect claim is not approved if the product has been subjected to “unnecessarily harsh treatment”. Our products are designed to withstand a great deal (for example, our “drop test”), but if a lamp shows signs of having been “used as a hammer” or similar, the claim will be rejected. See examples here:

What is the operating time of the products?

This depends on many factors. Our products are typically supplied with 2600mAH (milliampere hours) but also range down to 800mAh. The higher the mAh rating, the longer the operating time per charge. The longest operating time is achieved by using the lowest lumen output or when a rechargeable battery is charged to 100% power – but it also depends on the battery itself. For example, we supply AAA dry cell batteries from a European-recognized manufacturer (currently Duracell) in our PRO light series. The operating time is indicated on the basis of these batteries, but if the end user changes to lower quality batteries, the operating time will decline. Therefore, the stated operating times are indicative and apply for the batteries we supply with the product. Storage at low temperatures can also have a negative impact on the operating time.

What is the charging time for the products?

This depends on numerous factors, including the current power level of the batteries at the start of use, the battery type (“14500”, “18650”, etc.), battery capacity (mAh), voltage (V), and “power supply”. Our products are always supplied with partially charged batteries. We primarily state the charging time for a battery that is dead.

What is “output”? And why do the products have different “outputs”?

This is mostly used as another term for “lm/Lumen”. Older end users typically require a higher output to see a point clearly than younger users. Many of our products have adjustable lumen levels. Output and “operating time” are also impacted by the use of dry cell or rechargeable batteries (some of our products can use both battery types).

How do I handle the products correctly in terms of safety?

All of our products are covered by the same safety instructions to prevent personal injury and damage to the product and surrounding area.

What is Color Temperature?

“Color Temperature” is measured in the unit “K/Kelvin”.
