26mm-Diameter Linear Fluorescent Lamps (also called T8) The most standard linear fluorescent lamps in Europe. Diameter of 26 mm. |
|
Performance: |
The T8 is among the most efficient fluorescent source. In addition, their cost is now lower than the costs for T12 lamps.
T8 lamps are available with three different types of phosphor coatings:
The halophosphate type 26mm lamps produce approximately the same light output as the 38 mm diameter lamps of the same length and colour, but consume around 8% less energy. The Triphosphor type version not only consumes around 8% less energy but also produces approximately 10% more lumens and has a higher Colour Rendering Index. This latter version shall therefore be preferred. |
Applications: |
The 26 mm diameter fluorescent tubes have replaced the 38 mm diameter tubes as the standard for new installations.
The T8 triphosphor lamps are suitable for applications where good colour rendering is required (e.g. offices). The very high colour rendering multiband phosphor lamps are most suitable for lighting in galleries, museums, art shops, etc. and other applications where very high colour rendering is required. |
