The Erden E4 is a medium-powered inground 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.
