Are you a lighting importer or product developer?
Our Albany campus houses a photometric laboratory, which is available to assist the lighting industry and is capable of measuring many characteristics of lamps and luminaires.
Our cost-effective testing can be used to:
- flag underperforming products
- develop products through iterative procedures using different control settings or optics
- check light source output for compliance with regulations
- test photometric properties over life
Standards services are listed below.
|Standard Testing in Integrating Sphere|
|Spectral Distribution||Wavelengths in the visible range (380 nm to 780 nm).|
|Chromaticity Coordinates||Colour of a light source in terms of (x, y) and (u’, v’) coordinates set against the relevant ANSI/NEMA quadrant.|
|Correlated Colour Temperature||Colour of a light source in Kelvin.||2855 K|
|Luminous Flux||Amount of light emitted in all directions in lumens.||370.1 lumens|
|Chromaticity Difference||The position of chromaticity coordinates relative to the blackbody locus.||0.00015 Duv|
|Colour Rendering Index (Ra)||How realistically a light source can reproduce the colour of an object.||Ra=83.2|
|R1 – R8||Colour rendering of the eight individual samples that comprise Ra.||R1=82 R2=93 R3=94 R5=83 R6=93 R7=81 R8=59|
|R9||Colour rendering of a specific red sample. This is not included in Ra.||R9=10|
|R10-R14||additional samples that are not included in Ra.||R10=85 R11=80 R12=77 R13=86 R14=98 R15=75|
|TM-30 Value||Colour rendering of a light source using IESNA TM-30 methodology.||Rf=82 Rg=93|
|Power||Total power used by the light source and associated ballast/driver in watts.||5.62 W|
|Power Factor||Power factor of the light source when used with the associated ballast/driver.||0.56|
|Luminous Efficacy||Luminous flux produced per watt of electricity.||65.9 lm/W|
|Illuminance||The amount of light (per square metre) that falls on a surface. Measured in lux.||21 lux|
|Luminance||The intensity of a source or surface (in the direction of the observer) divided by the area of the source (or surface) seen by the observer. Measured in candelas per square metre. Often used to determine the “brightness” of surfaces, such as signs.||168 cd/m2|
|Flicker||Modulation of the light output.|
|Other services||Contact us to discuss.|
