Data Sheet HLMP-D150, HLMP-D155, HLMP-K150, and HLMP-K155 T-1 (5 mm), T-1 (3 mm), Low Current, Double Heterojunction AlGaAs Red LED Lamps Description Features These solid state LED lamps use double heterojunction Minimum luminous intensity specified at 1 mA (DH) AlGaAs/GaAs material technology. This LED material High light output at low currents has outstanding light output efficiency at very low drive Wide viewing angle currents. The color is deep red at the dominant wavelength Outstanding material efficiency of 637 nm. These lamps are ideally suited for use in Low power/low forward voltage applications where high light output is required with CMOS/MOS compatible minimum power output.
