Cautions:
*1. Optical performance should be evaluated at Ta=25 ℃ . Only If LED is driven by high current, high ambient temperature
& humidity condition. The life time of LED will be reduced. Operating life means brightness goes down to 50% of initial
brightness. Typical operating life time is an estimated data.
