FAQ - Frequently Asked Questions?
What do Em and Emax stand for?

The specifications Em = Medium illuminance and Emax = Maximum illuminance are the result of laboratory measurements at 25 ° C with a burned-in lamp (Waldmann standard) in a closed, black room. These values can therefore differ at the installation site due to measuring tolerances and other environmental conditions.

What is the difference between diopter and magnification factor?

The diopter (dpt) refers to the refractive power of a lens. The magnification factor is the degree by which the viewed object is magnified.

Magnification factor (x) = Diopter of lens : 4 + 1

What does glare-free mean?

Waldmann offers glare-free technologies for various requirements. Examples include a parabolic louver in combination with a fluorescent lamp or special conical prismatic screen (CDP) for particularly low-glare LED lighting solutions.

Where can EPA-luminaires be used?

(= Electrostatic Protect Area)

Electrostatically protected area (ESD work station), in which electrostatic charge is prevented by antistatic equipment. Waldmann luminaires bearing this symbol may be used in corresponding areas.

When do you need toughened glass?

Waldmann generally uses glass with a thickness of 4 mm as standard to ensure high impact strength and resistance. The glass can withstand even the strongest flying chips without scratching. However, if the glass does break, it shatters into small pieces to ensure a high degree of safety.

What is color temperature?

The color temperature, measured in Kelvin, represents the color impression of a light source.

• Warm white < 3,300 K

• Neutral white 3,300 – 5,000 K

• Daylight white / cool white > 5,000 K

What is color reproduction?

The maximum value Ra = 100 corresponds to the natural color reproduction of sunlight. Poor color reproduction values for lamps have a negative impact on contrast sensitivity (e.g. for surface inspections, quality inspections, precision work). The colors also look unnatural. Lamps with a minimum color reproduction value of 80 should therefore be used where high / maximum requirements exist for these two features.

What is cooling agent/lubricant resistance?

Waldmann machine luminaires are tested for resistance to a wide range of cooling agents and lubricants in machine tools. Due to the large number of products on the market and ongoing development in the area of cooling agent / lubricant resistance, Waldmann cannot provide a general guarantee for material resistance. Waldmann can provide individual resistance tests.

How many hours does the LED service life last?

The service life specification is generally qualified with two values: L70 / B50. Waldmann luminaires achieve an LED service life of 50,000 hours if the specified maximum ambient temperature is observed. After this time, the luminous flux of 50 % of the LEDs (B50) is 70 % (L70) of the original value.

What is the difference between power consumption and lamp consumption?

The specification in watts for the power consumption of the lamp differs from the consumption of the luminaire. The latter value refers to the entire lighting system, i.e. including the ballast and LED driver.

What does the specificaiton fluorescent lamp type T16 = T5 mean?

T = tube; number = diameter in eighths of an inch (T5: 5 / 8“) or millimeters (T16: 16 mm ≈ 5 / 8“). Specifications T5 and T16 are therefore identical.

What is Light Forming Technology?

With this technology, the punctiform lighting characteristic of LEDs is transformed into extremely homogeneous area light. This new development from Waldmann ensures optimum glare-free lighting.

What is Ray Mixing Technology?

This innovative technology uses the total reflection of special reflector housing. All emitted light beams are therefore optimally mixed whereby punctiform LED light sources are converted into diffuse light.

What kind of classes of protection for electrical equipment are available?

SK I (earthing protection): All electrically conductive housing components are connected to the protective earth conductor system of the fixed electrical installation.
SK II (protective insulation): Reinforced or double insulation between the mains circuit and output voltage or metal housing. There is generally no connection to the protective earth conductor.
SK III (protective extra-low voltage): Equipment in class of protection III operates with protective extra-low voltage (PELV) and requires reinforced or double insulation between mains circuits and the output voltage in mains operation.

What is the function of the visualizer / segment switching option?

The Visualizer function allows the separate switching of light segments in scenarios. This brings forth texture-emphasizing effects that make it easy to detect even the tiniest of faults, such as cracks or differences in the surface

What is an add-on lens?

Bonded add-on lens that provides greater magnification in a small field of vision of the magnifier. The diopters of the magnifier and the add-on lens are added.

What does Zhaga mean?
Zhaga is a consortium of industrial enterprises with the goal of standardizing the interfaces of LED light modules.
