LED Measurement

New measurement protocols and test procedures are currently being developed for LEDs. Methods to measure total luminous flux, luminous intensity, color temperature, color rendering, lumen depreciation, and electrical characteristics are all under development or revision to accommodate specific attributes of LEDs that differ from other lighting technologies. The LED Measurement Series explores these topics.

• Solid State Lighting Standards — an overview and listing of industry standards and test procedures relevant to LED products
• Color Rendering Index and LEDs — explains why CRI is not necessarily a reliable indicator of LED color rendering ability
• Luminaire Efficacy — describes the preferred energy efficiency metric for LED lighting
