Why Use TL84 / 840 Lighting for Colour Inspection?
A colour can appear different under different light sources. This phenomenon is particularly important when comparing paints, coatings, plastics, textiles and other coloured materials.
The Philips 840 lamp provides a 4000K Cool White lighting condition that can be used as part of a controlled visual inspection environment.
In professional colour assessment applications, users may compare a sample under multiple light sources, such as daylight and TL84/840 illumination, to help identify differences in colour appearance.
For this reason, the Philips MASTER TL-D 18W/840 can be a useful replacement lamp for compatible colour matching and quality-inspection equipment.
