It’s been a long journey from the incandescent light bulb that was invented in 1879 to the modern light sources of our day. While the light bulb produces significantly more warmth than it does light, modern discharge lamps are over five times more efficient at producing light.

Researchers and technicians are already working on the light sources of the future. These are not only superior in terms of their energy-saving aspect, but are also designed to create lighting conditions that are physiologically sound for humans.

Such modern lamps and lighting concepts create a pleasant and healthy environment for working and living spaces.
