C-state lighting technologies, light-emitting diodes (LEDs) will probably become the most used light sources in chromotherapy. Some LED-based chromotherapy lamps are already available on the market. The main interest in LED lamps—in addition to their energy efficiency and long lifetime—is that they can provide various colors directly depending on the nature of the semiconductor inside without using any filter. Is the use of LEDs in chromotherapy without any risk?
