16mm-Diameter Linear Fluorescent Lamps
(also called T5)
Introduced in 1995, they are the newest generation of linear fluorescent lamps with a diameter of 16 mm only.
Performance: These slimmer lamps are 7% more efficient than the 26 mm (T8) fluorescent lamps (efficacy of 89 lm/W for T8 lamps compare to 95 lm/W for T5 lamps).
In addition, T5 tubes can come with an optimised reflector that further improve the savings compared to a T8/reflector system.
Applications: Each new lamp will require a new socket, ballast and fixture. They should therefore be reserved for new installations.
Lifetime: 14 – 80 Watt
3000 – 6000 Kelvin
80 – 100 lm/W
