Natural halogen light renders whites thanks to its UV tail & Pneuma LED can be emulated with a peak of violet light which also excites whitening agents, while avoiding the harmful effects of UV radiation.

PNEUMA-LED-WHITENESS GRAPH

Test subjects were asked to rank calibrated white samples accurately from least white (Rank 1) to most white (Rank 6). Under a blue-based LED, the ranking was random, as subjects could not tell one white from another. Under a violet-based LED, they ranked the samples perfectly.
