Light Output Performance

Light Output from Luminaires is defined by three important

factors:

1) The efficiency of the luminaire in directing the light from the lamp onto a surface.

2) The amount of light trapped in the luminaire housing.

3) The amount of light which comes out of the lamp up above a horizontal plane.

What Type of Products Can We Test?

• Various Types of Luminaires including:

– Indoor Light Fixtures

– Residential Light Fixtures

– Street Lighting Fixtures

– Area Lighting Fixtures

– Spotlights

– Floodlights

– Flashlights

Industry Standards

• IESNA LM-79-08 Approved Method for Electrical and Photometric Measurements of Solid-State Lighting Products

– Applies to both LED Luminaires and LED Light Sources intended for retrofit applications.

– Measurements include:• Total Luminous Flux• Electricals (Input Voltage, Current, & Power)• Luminous Intensity Distribution• Color

– Chromaticity – Correlated Color Temperature– Color Rendering Index

• Spectral Power Distribution• One Sample per Model Required for Testing

What Does the Test Report Include?

Typical IESNA LM-79-08 Report Includes:

• Luminaire Efficacy, Minimum Light Output, Zonal Lumen Density

• Color Measurements (CCT, CRI, Chromaticity) and Electrical Measurements

• Spectral Distribution over visible wavelengths (mW/nm)

• Absolute Intensity Candlepower (cd) Summary table

• Isocandela Plot

• Luminance Summary table

• Illuminance – Cone of Light Plot

• Illuminance – Isofootcandle Plot

• Illuminance – Roadway Isofootcandle Plot (if streetlight)

• Picture of sample

• IES File

Industry Standards

• IESNA LM-80-08 Approved Method for Measuring Lumen Maintenance of LED Light Sources

– Details specific method for measuring Lumen Depreciation of LED Arrays and LED Modules.

– Measurements include:

• Lumen Maintenance to 70% Depreciation

• Measurements taken at 7 points over three temperatures (Ts = 55°C, 85°C, and “x” = client choice)

• Measurements taken at 1,000 Hour increments to 7,000 hours.

• Color Maintenance also tested to monitor color shift at same points.

• 3 Samples Required for Testing (One per Temp.)
