Features
The proprietary SK21 is a miniature linear, line voltage LED luminaire that mounts, powers and aims with great ease. The extruded aluminum fixture mounts with a pair of small spring clips. It powers, simply by inserting the accessory cord and plug. Seamlessly row mount by connecting adjacent fixtures end-to-end or use interconnect cables for illuminated runs up to 40’. With the hardwire adapter, fixtures can dim to 5% with 0-10V controls. The SK21 is available in four lengths with four color temperatures and 95 CRI.
