HELI-R SMD LEDs Kingbright HELI-R SMD LEDs feature: energy-efficient reverse-mount LEDs for single colour, bi-colour, RGB, and IR options. These LEDs offer energy efficiency, low-cost illumination, and high brightness. The HELI-R LEDs are based on chips made from AlGaInP. These LEDs must be electrically grounded and it is recommended that anti-electrostatic gloves or wrist bands are used while handling. The HELI-R LEDs can be damaged by electrostatic discharge and power surges. These LEDs are ideal for use in backlights, status indicators, smart applications, and healthcare applications.
