What effect renders UV lamp when selecting the colour with use light booth?
Generally the UV lamp in a light booth is used to check for the presence of fluorescence in a sample. If the sample is viewed under the UV lamp (only) and appears to glow in some color other than a deep violet, then it is fluorescent (absorbing the UV and emitting at different wavelengths). The UV lamp is also used with the daylight illumination in the booth to enhance the UV content, making it more like real daylight, to better render the appearance of fluorescent materials in daylight. It won’t make any difference for non-fluorescent samples.
