The HLMP-D150/D155 and HLMP-K150/K155 series, from Avago Technologies, are low current red LED lamps. They are solid state LED lamps which use double heterojunction (DH) AlGaAs/GaAs material technology. This material gives this family of LEDs a high light output efficiency at very low drive currents. They come in a deep red colour with a dominant wavelength of 637 nanometers.
The HLMP-D150/D155 and HLMP-K150/K155 LEDs are ideal for applications where a high light output is required with minimum power. Suitable applications for this family of LEDs include; low power circuits, battery powered equipment and telecommunication indicators.
