SUMMARY

To measure lumen output, lumen efficiency, and color temperature of a street lamp, various testing methods are outlined in the 'ASTM Standards on Color and Appearance'. It is crucial to differentiate between photometric and colorimetric measurements, as opposed to radiometric quantities. For practical measurement solutions, Vernier's equipment is recommended, although it is not research-grade quality. This approach allows for accurate assessments of street lamp performance.

PREREQUISITES
  • Understanding of photometric and colorimetric measurements
  • Familiarity with ASTM Standards on Color and Appearance
  • Basic knowledge of lumen and lumen efficiency concepts
  • Awareness of measurement tools, specifically Vernier equipment
NEXT STEPS
  • Research ASTM Standards on Color and Appearance for detailed testing protocols
  • Explore photometric measurement techniques using Vernier equipment
  • Learn about the differences between photometric and radiometric measurements
  • Investigate additional measurement tools for street lamp testing
USEFUL FOR

This discussion is beneficial for electrical engineers, lighting designers, and anyone involved in the testing and evaluation of street lighting systems.

There are a variety of applicable tests and measurement methods listed in 'ASTM Standards on Color and Appearance'. Note that you are asking about photometric and colorimetric quantities, not radiometric quantities.

Check www.vernier.com. Their equipment is not research quality, but it may be what you're looking for.
