The Erden E4 is a medium-powered ingrade uplighter that combines technology and performance in a modern form factor. Available in white, colour changing and tunable white light engines, the Erden E4 is packed with features including EasyGlow visual comfort and CoolDrive thermal management technologies. PowerSync allows for highly granular digital control via common protocols using mains voltage. CoolDrive active thermal management engages as internal temperatures increase to keep light output consistent. Only under extreme conditions will the luminaire take control and dim the output gradually and smoothly.
