GONIOPHOTOMETRIC MEASUREMENTS: (Top)

For every luminaire fastening	70,- €

For every goniophotometric measurement at :
15° steps for planes	50,- €
10° steps for planes	65,- €
5° steps for planes	110,- €

For each Eulumdat (.ldt)* file	10,- €
For trafic lamp measurements	85,- €

Prices are given for luminairs being symmetric in planes C0-C180 & C90-C270,
in plane C0-C180 or in plane C90-C270, which give light only to either lower or
upper hemisphere, where measurements in planes are made in 2.5° steps.
For non-symmetric luminaires measurement prices should be multiplied by 1.5.
For rotational symmetric luminaires measurement prices should be multiplied by 0.7.
If a luminaire gives light to the upper sphere not exceeding 140° and if the geometry
of it is suitable for measurement in one go, measurement prices are multiplied by 1.3
For luminaires sending light in both hemispheres and where the measurements in
planes have to be made from 0°-180°, prices both for fastening and measuring
should be multiplied by 2.
If measurements in planes are made in 5° steps, measurement prices are multiplied with 0.7.
If measurements in planes are made in 1.25° steps, measurement prices are multiplied with 1.5.
If measurements in planes are made in 0.5° steps, measurement prices are multiplied with 2.
For cases other than explained above, ask for special prices.
The exact lumen output of the lamp(s) used in the luminaire to be measured should be
known. Therefore, if the lamp has not already a secondary standart certificate, it should
be meausered in the integrating sphere by YFU.

INTEGRATING (ULBRICHT) SPHERE MEASUREMENTS: (Top)

For every lamp	95,- €
For same type of lamps after the first one	65,- €
For every luminaire light output ratio measurement	150,- €

The lamps to be measured in integrating sphere should be aged at least for 100 hours.

REFLECTOR DESIGN: (Top)

Reflectors for point light sources:
Simple rotational reflector	500,- €
Complex rotational reflector	800,- €
Reflector which should comply to a certain standard	1.200,- €

Reflectors for line light sources:
Simple reflector for sources like: straight Fl, compact Fl, long halogen	400,- €
Reflectors necessitating translations of straight lines or curves	600,- €

MISCELLANEOUS MEASUREMENTS: (Top)

Regular or diffuse reflectance	60,- €
Regular or diffuse transmittance	60,- €
Absorbtance	120,- €
Diffusion factor by reflectance	90,- €
Diffusion factor by transmittance	90,- €
Luminance (mean value) for primary light source	60,- €
Ratio of min.-max. luminance values for primary light source	80,- €
Louminous homogeneity ratio for traffic signal heads	80,- €
Phantom signal for traffic signal heads	120,- €
