The first decade with white LED light reveals how designers have implemented new technology in existing housing, added LED as part of a product group or created a unique design specifically for LED.


Today’s high-power LEDs are of course much more efficient than the LEDs of the first generation. Early on, LED luminaires were used mainly as a general table light and not as a task light to meet the ergonomics standards of 500lx on the working area because the light output was too low. To raise the light output, designers increased the number of LEDs per luminaire. Later on, with the change to high-power LEDs the number of LEDs per luminaire declined drastically. State-of-the art warm white LED technology with a light efficacy of about 75W/lm just requires one third of energy for the same lumen output if compared to low-voltage tungsten lamps with about 25W/lm, thereby enabling task lights for offices with less than 10W. The longevity of LEDs with 50.000 hours facilitates a use for 20 years when used on workdays for 10 hours.
