When evaluating LED luminaire performance claims it is important to compare a standardised set of quality criteria measured in compliance with the appropriate standard.
Luminaire
Manufacturers Design Data
These
quality criteria are designed to ensure that performance claims can be matched
against traceable data.
This
data is summarised below:
1) Rated input power (in W)
2)
Rated luminous flux (in lm)
3) LED luminaire efficacy (in lm/W)
4)
Luminous intensity distribution
5)
Photometric code
5a) Correlated Colour Temperature (CCT in
K)
5b) Rated
Colour Rendering Index (CRI)
5c)
Rated chromaticity co-ordinate values (initial and maintained)
5d)
Maintained Luminous Flux
6) Rated life (in h) of the LED module and the
associated rated lumen maintenance (Lx)
7) Failure fraction (Fy),
corresponding to the rated life of the LED module in the luminaire
8) Ambient temperature (ta) luminaire
9) Power Factor
10) Intensity Distribution
11) Drive Current
12) Optical Risk
