A light-emitting diode (LED) emits light when its semiconductor draws electric current. The LED converts electric energy directly into optical energy, responding quickly and making possible pulsed lighting.

Since an LED emits light through a semiconductor device, its life is many times longer than that of other light sources however, it can be affected by the operating environment.

LEDs can be designed to efficiently emit a specific color by adjusting the materials used in the semiconductor compounds.

“Light” is one of the most important factors for the growth of plants.

The IS-series is being used in many research laboratories in Japan for different research applications.
