The relevant criteria of product quality of modern technical luminaires have changed fundamentally in the recent past. The transformation of nearly all product segments from the operation of a replaceable fluorescent lamp with its relatively robust operating characteristics to the optimized integration of highly specialized LED components has necessitated this change.
For the assessment of the quality and serviceability of LED luminaires, it must be taken into account that the data given in the technical product documentation should have been determined clearly and on a reliable basis. In particular, for the luminous efficacy and the useful life often misleading information is made in the market. These can not only lead to a wrong assessment of the product quality, but may even lead to planning errors in lighting design. For this reason, TRILUX basically uses the definitions used for the ENEC + performance marking in its documentation (see also chapter 220.127.116.11 "ENEC+, identification symbol for LED luminaire performance").
