One manufacturer gives you a service life in hours under L80 at 25°C, another specifies in L70 at 35°C, and a third manufacturer only specifies L70 without any temperature (25°C then applies). Which luminaire is better or has the longer life, and in which ambient temperature? This small online tool can convert these service life specifications for you. Convert an L80 luminaire to an L70 and vice versa.

With your service life specifications, the TRILUX LIFETIME calculator can determine the maintenance factor in a second step. For this purpose, simply enter the selected maintenance interval (e.g. an office with 30,000 hrs.) to get an individual maintenance factor.

As part of this the luminaire luminous flux maintenance factor (LLMF) and lamp survival factor (LSF) are calculated directly. The luminaire maintenance factor (LMF) and room maintenance factor (RMF) must be entered manually.

If the luminaire or connected light management system supports constant luminous flux technology (CLO), the result also outputs a performance service life factor (PLF).
