3.5 Colour characteristics
General colour rendering index (R
a
): ≥80
Correlated colour temperatures:
2700 K (/827,incandescent) 4000 K (/840,cool white)
3000 K (/830,warm white) 5000 K (/850, daylight)
3500 K (/835,white 3500) 6500 K (/865,cool daylight)
Chromaticity coordinates:
Note: Chromaticity coordinates at 35 ªC ambient temperature (design
temperature). At 25 ªC ambient temperature the chromaticity
coordinates will differ slightly from the above values because of the effect
of the changing mercury pressure with the ambient temperature.
3.6 Spectral power distribution
The normalized spectral power distribution of a ‘TL’5 lamp is given
in the following diagrams.For UV radiation see the table in section
2.9.2.
