Spectra Tech employes sophisticated equipment to measure and evaluate light levels and lighting pollution on property adjacent to sources of high light output or glare (expressed in terms of lumens, lux, or footcandles).
We can also provide assistance in designing solutions to reduce excessive light levels and glare.
Units of light level:
- footcandles
lux
lumens - Light level testing requires the use of a precision light level meter.
- Test readings are usually taken in multiple locations, typically along a property boundary.
- Results are compared with local ordinance restrictions, or with national guidelines to determine if intruding light levels are a nuisance.
- Report and expert witness testimaony available to support findings in a zoning hearing or court case.
