Lumileds today introduced the LUXEON MX, a multi-die emitter that delivers industry leading efficiency and flux for outdoor fixtures and high bay lighting applications. Lighting fixtures benefit from the emitter’s 1,200 lumen, 150 lm/W efficacy, at 85°C (4000-6500 K and 70 CRI) which enables a system efficiency of 120 lm/W when driven at 700 mA.
