Light booth type «LBM-B-700» for visual assessment with four different, standard light sources.
Light booth type «LBM-B-700»
The light sources:
- «D65» artificial daylight - lamp with color temperature of 6500 K
- «TL84» fluorescent light – lamp with color temperature of 4000 K
- «A» home light (evening light) – lamp with color temperature of 2856 K
- «UV» ultraviolet lamp for evaluating optical brighteners, whitening agents and fluorescent dyes / pigments
A digital operation hours counter controls the number of hours that each of the four lamps is on. Consistent spectral light energy distribution is thus guaranteed.
Fifth light source:
«D50» artificial daylight, lamp with color temperature of 5000 K
«D75» artificial daylight, lamp with color temperature of 7500 K
«H» Horizon artificial daylight, lamp with color temperature of 2300 K
«CWF» fluorescent light, lamp with color temperature of 4150 K
