This system offers excellent properties such as good luminous flux behaviour, impressive economy and improved environmental compatibility. With a tube diameter of only 16 mm, these lamps offer an extremely high luminous efficacy of up to 104 lm/W (at 35 °C). They are designed for ECG operation and are up to 20 % more efficient than LUMILUX T8 lamps. With hot restart ECGs, T5 lamps achieve an average life of 20,000 hours and a service life of 16,000 hours. They also enable extremely slim and compact luminaires to be created because their volume is up to 50 % less and their length 5 cm shorter than comparable T8 lamps.
