Notes:
1. All High-Flux LEDs represented here are IEC825 Class 2 for eye safety. See Application Brief I-009 and I-015 for details.
2. Always protect device against reverse voltage.
3. Projected value. Tested typical value to be announced at a later time.
4. The dominant wavelength is derived from the CIE Chromaticity Diagram and represents the perceived color of the device.
5. Values derived from data on T-1
