6. Luminaire type New: Mithra (Stela range will follow soon). Choose the type of luminaire used in lighting calculation, i.e. Luma 1, 2 or 3. L-Tune output shows all solutions based on this selection. In addition L-Tune also presents alternative solutions, if any, in other luminaire types. However only as an indication as the photometrical characteristics of the different luminaire types differ.

Factor, MF < 1.
This because the Luminaire Maintenance Factor, LMF < 1.
Therefor a LMF value < 1 must be used to acquire a realistic amount
of lumen for your solution11. L-value & Lifetime request
L-value (LLMF) between 0.10 and 1.00. Defines the maximum
accepted lamp lumen depreciation over the total expected life of
the light source.
For instance L70 means that you define the expected life of the LED
at which it produces 70% of the initial nominal lumens (so you
accept 30% lumen depreciation).
For CONSTAFLUX enter 1 (= “no” lumen depreciation).
Default value is the LLMF value given in the LLMF field above.
NOTE: Despite the choice of CONSTAFLUX, one always
should use a luminaire maintenance factor, LMF < 1
due to pollution of the luminaire
Minimum required lifetime,
f.i. 20 years is approximate 80.000
hrs (@4100 hrs/year).12. Dimming options
Depending on the chosen Dimming option, extra
input about dimming hours, levels and choice of
secondary switch/control modules are shown.
NOTE: All calculations for savings due to dimming
are based on 4100 hrs per year12.1. No dimming

All possible L-Tune solutions are based on this
selection. The blue, yellow and green
indicators are only given for these solutions.
In addition L-Tune also presents alternative
solutions (if any) in other luminaire types
(presented in grey), however only with an
indication of consumed power over life, as the
photometrical characteristics of the different
luminaire types differ.

redefine the required luminous flux. This
redefined flux can be used again as input for
