KEY FEATURES Dimensions in mmDIMENSIONS Ø46 FIXED COMPACT INTERIOR/EXTERIOR LED DOWNLIGHT The compact LD780 has an excellent size to output ratio that is ideal for general downlighting and the highlighting of walls and columns within interior, exterior and marine applications. With a diameter of just 46mm, the aluminium bezel can be specified in a wide range of paint finishes and features a deep recessed optic within the body to ensure ultimate low glare. Available LED engines include E3 and F1, offering colour temperatures of 2200K-5000K and a variety of beam angles, including a tight 12° narrow beam with medium options for more general downlighting. Though compact, the LD780 provides brilliant thermal and light output performance, with a single optic generating a superior beam shape and no multiple shadows. LD780
