SSL Spektri 80 Lightmeter

Color temperature measurement with Lighting Navigator The simplest solution for successful light projects The Light Navigator from the well-known manufacturer Asensetek is more than just a luxmeter. Besides the color temperature measuring, also the color rendering index CRI/Ra can be determined and the light spectrum can be displayed. Thus the Light Navigator is the perfect device for all those, who just want to check the technical data of a lamp or a light, or measure their consisting light installation rapidly. Additionally different standards are deposited for the individual countries. That way it's possible to check if your present installation meets with the standards, with little research only.  The meter works as an independent sensor, just like the other Lighting Passport devices from Asensetek and is coupled via bluetooth with your smartphone or any other smart device (iOS or Android). Download the app, connect via bluetooth and you're ready to go.       Technical data of the Asensetek Lighting Navigator:   Size   Width: 63.1 mm   Depth: 17.5 mm   Height: 63.1 mm   Net weight   92 g ± 1 g (with stand)   Wavelength range   380 ~ 780 nm   Illuminance range Measurable   50 ~ 50,000 lux    Optical resolution (FWHM)   10 nm   Accuracy (@ 1,000 lux Standard Light Source)   CCT:± 3.5 %   Illuminance:± 5 %   Integration time   6 ms ~ 16 s   Operating temperature/   humidity range   0 ~ 35 °C, relative humidity under 80 % with no condensation   Storage temperature/   humidity range   -10 ~ 45 °C, relative humidity of 85 % or less (@ 35 °C) with no condensation Measuring the color temperature and counting with the app of Lighting Navigator     Main Features   Filter   Measurement   Comparison    Measurement Capability   CCT   CRI (Ra)    Illuminance   Spectrum   R9 Rank   IEC-SDCM Rank (MacAdams)   Other Features   Photograph, Note, Auto Connection,    Standard Estimation, GPS Orientation,   Social Media Integration   Language   English, Traditional Chinese, Simplified Chinese   AppStore   Google Play

Mavospec Base M521G | Lite M530G - Spectrometer from Gossen The MAVOSPEC BASE and its "little brother" the MAVOSPEC LITE are perfect for everyday measurements of all conventional and modern light sources such as LEDs or OLEDs. In any lighting situation - from private residential to professional to industrial - compliance with defined values and standards, as well as consideration of quantitative and qualitative requirements, is crucial for the lighting effect achieved. The MAVOSPEC light meters support light planning, find problems in electrical installations and offer simple light measurement and documentation for every user. All characteristic measured variables such as illuminance, color temperature, color rendering index, etc. are determined from the measured spectrum and displayed in an understandable way on the color display. The operation is user-friendly and intuitive via ring controller and few keys. Versatile application possibilities and a wide range of use make the MAVOSPEC BASE and MAVSPEC LITE the reliable partner of the lighting specialist for selection, tuning, verification, comparison, evaluation of the light and color quality of different light sources or different manufacturers.

It provides information about the colour characteristics and can be used to compare the colour composition of different light sources. The colour rendering property can also be derived from this, because missing or reduced areas in the spectrum cause errors in colour rendering. Color rendering index - measurable with both devices Ra is a measure of the colour rendering properties of lamps whose theoretical maximum value is 100. The higher the colour rendering index, the better the colour rendering properties of the lamp. The most natural colour rendering possible is achieved by using lamps with Ra > 90. Ra is the arithmetic mean of the color deviation of the first 8 of 14 test colors according to DIN 6169, with the color rendering index Re, calculated across all 14 test colors and the additional test color 15 (Asia Skin Color), which also takes saturated colors, leaf greens and skin tones into account. DIN EN 12464 defines the colour rendering properties of lamps for lighting in different types of rooms and activities. color coordinates - measurable with both devices are a measure to precisely define a color or the color location belonging to the color in the CIE standard color system. The human eye has sensory cells for the perception of the three primary colours red, green and blue. The spectral eye sensitivity curves were determined by the CIE for the normal observer in 1931 and show the sensitivity for the individual wavelength ranges. Flicker - only Mavospec Base refers to changes in the brightness of the light due to voltage fluctuations. The noticability threshold for luminance changes is a frequency-dependent variable that indicates from which relative luminance change at a given frequency this is perceived. These fluctuations have an impact on human health. A good LED driver regulates voltage fluctuations and avoids flicker. The flicker value is a measure of the quality of the lamp or luminaire and should be as low as possible. Illuminance strength - measurable with both devices indicates the intensity with which a surface is illuminated. It is one lux if the luminous flux from one lumen illuminates the surface of one square metre evenly. One luxmeter is used to measure illuminance on horizontal and vertical surfaces. However, it does not reflect the impression of brightness of a room, as this depends largely on the reflective properties of the room surfaces. Under normal lighting conditions, no uniform light distribution is usually achieved, which is why specifications in standards usually refer to average illuminance. It is calculated as the weighted arithmetic mean of all illuminances in the room. Colour temperature - measurable with both devices is a measure to quantitatively determine the respective colour impression of a light source. The unit of colour temperature is Kelvin (K). In concrete terms, it is the temperature whose light effect is most similar to the colour to be described at the same brightness and under fixed observation conditions. Color rendering IES TM-30-15  - only with Mavospec Base is a new IES standard for evaluating the colour rendering of light sources, which works with 99 reference colours distributed over the entire colour space. It therefore includes considerably more colours and shades in the calculation of the Fidelity index Rf, which describes the same relationship as the colour rendering index Ra. The Gamut-Index Rg provides information regarding color saturation and color shift similar to the Gamut-Area-Index GAI of the previous observation of color rendering.
