This LED spotlight for a two-phase rail system delivers a light output of 840 lumens and is equipped with two interchangeable lenses for different reflected beam angles. The L-shaped support element integrates a rotary support, the electronics as well as a shaft, which leads to the pivoting LED arm. The arm provides a visually appealing contrast to the tangentially placed light cylinder. The interchangeable lens head with its functional ring heat-sink complement the product concept.
