Start with Where the Light Will Work
Landscape lighting emphasizes color and distribution, studio lighting image quality, and portable lighting energy and size. The application is the starting point for selection.
From Component to System
Light source, optics, driver, cooling and structure interact. Breaking requirements into these elements is more useful than pursuing a single larger parameter.
Set Reproducible Validation Conditions
Keep driver, thermal conditions and test distance consistent when comparing samples. Record measurements and visual experience as a basis for further discussions.
