Take into account the measurement range, type of samples, needed precision, any relevant standards, and your industry.

An inappropriate viewing angle may lead to reflections or color shifts in the light. The correct angle of 45 or 0 will provide the real color of the assessment without the distraction of glare.

Techniques of measuring color are visual color comparison, colorimetry (with colorimeters) and spectrophotometry (measuring spectral reflectance), and image analysis. Both techniques measure the reflection or absorption of light by materials and are commonly quantified. Therefore standardized in color spaces such as CIELAB or RGB.

The color measurement theory is the quantification of the interaction of materials with light, either absorption, transmission, or reflection. It employs standard colour spaces (such as CIELAB) and devices (colorimeters, spectrophotometers) to code the visual colour into objective and reproducible data.

Ambient light may affect the test results and must therefore be kept to a low level for accurate haze meter results. 

Flickering lamps, color shifts, and uneven lighting are common faults, which can be corrected by changing the tubes, cleaning the interiors, and re calibrating the light system.

Replace when the total hours exceed rated life, decrease in brightness, or the color temperature shifts beyond tolerance.
