Key Notes: Flux values at 25°C are for reference only, and calculated flux values at 700 mA and 1 A are also for reference. Emphasizes adherence to chromaticity bin restrictions and notes that shipments may include higher flux bins than specified.

Spectral Power Distribution: Graphs illustrate the relative spectral power distribution for different LED colors, emphasizing their importance in determining LED performance.

Thermal Design: Discusses the impact of thermal resistance on LED performance, providing graphs that show maximum current versus ambient temperature for different colors. Stresses the need for minimizing thermal resistance to optimize lamp life and optical characteristics.

Performance Groups: LEDs are categorized into performance groups based on luminous and radiant flux. Detailed tables list the minimum and maximum flux values for each group, along with corresponding order codes.

Chromaticity: White LEDs are tested for chromaticity and sorted into regions defined by bounding coordinates. Tables with specific x and y coordinates for each chromaticity region are included.

Color Specifications: Lists various color codes for the Gen 2 series, including Blue, Green, PC Amber, Amber, Red-Orange, Red, Photo Red, and Far Red. The series is identified as XP-E, with color specifications ranging from Outdoor White to different CRI levels.

Reflow Soldering Characteristics: Compatible with JEDEC J-STD-020C standards. Key parameters include an average ramp-up rate of 1.2 °C/second, preheat temperatures between 120 °C and 170 °C, and a peak temperature range of 235 - 245 °C.

Compliance and Safety: Complies with RoHS and REACh standards, ensuring restricted materials are below threshold limits. UL Recognized, meeting fire and electrical enclosure requirements per ANSI/UL 8750. A vision advisory warns against looking directly at the lamp in operation due to potential eye injury.

Mechanical Dimensions: Detailed mechanical drawings specify dimensions and recommended PCB solder pad and stencil patterns. All measurements are in millimeters with specified tolerances.

Tape and Reel Packaging: Describes packaging standards for automated component handling, conforming to EIA-481D. Includes details on pocket dimensions and user feed direction.

Notes: Clarifies that luminous flux, radiant power, and other measurements are binning specifications and not operational specifications. Provides guidance on LED reliability, lumen maintenance, and moisture sensitivity.
