1 Confidential 1 Performance is the result of 3 groups of components Basic Things to Know about LED Lamps Mechanical & thermal LED components mechanical compatibility (shape, size) into an existing socket & fixture and thermal compatibility into existing socket & fixture Electrical LED components need to be 100% compatible with the electrical input power characteristics and 100% compatible with installed accessories (dimmers, transformers), while causing no non-compliances. Optical LED components perceived to deliver the same or better light effect as the original light source (beam shape, intensity, color point, color rendering), and perceived as equal or better light quality - variation between lamps Components Drive Performance & Price AL

2 Confidential 2 Color Binning Each color consists of several different bins The performance of each LED is unique Each LED is binned by three measurements: output color power CIE Chromaticity Diagram HPS Metal Halide

3 Confidential3 Higher output bins cost more Bins closer to the black body curve (whiter) cost more Manufacturers will not sell you just one bin in large volumes Manufacturers will not guarantee availability of specific bins Manufacturing Inspection & QC Sorting a.k.a. Binning High Output Low Output Warm Cool Binning All LED Components In A Product Batch Are Different

4 ConfidentialPage 4 Methods for Achieving Good Quality Light Use only one LED bin LED Binning Algorithms Optical treatments to reduce variation Fixture Calibration 4 Step McAdam w/ Algorithm 7 Step McAdam Ellipse Binning Algorithm example Light Quality LEDs and Standards

5 ConfidentialPage 5 4 Step McAdam w/ Algorithm 7 Step McAdam Ellipse Binning Algorithm example Light Quality LEDs and Standards Conforms to ANSI C78.377A PLC Optibin

6 ConfidentialPage 6 Light Quality Philips LEDs Philips Optibins CCT and hue tolerances for LEDs fall within a 4-step MacAdam ellipse, rather than 7-step ellipse defined by ANSI standard Optibin dictates the use of LEDs from bins which lie close as possible to the black-body curve within the 4-step ellipse. This proprietary algorithm intelligently combines LEDs from different bins, guaranteeing color uniformity for lamps purchased and shipped at different times SDCM – Standard Deviation of Color Matching A color difference of 1 SDCM step is not visible 2 – 4 steps is barely visible 5+ readily noticeable

7 Confidential Color Consistency Across Fixtures Binning Combined With Software Logarithms Improves Consistency 7 Page 7 LED Manufacturer Optibin® This is a Philips Exclusive
