Intended for use in an array of domestic and commercial settings, this MR11 spotlight from Integral LED employs four SMD Nichia LED units and an anti-glare refractor to produce a light akin to 20W halogen bulbs, but consume just 3.5W of power. Alongside its incredible efficiency, this lamp is also designed to manage heat more effectively than other spotlights, with a die cast aluminium and plastic composite body dissipating heat away from its essential components much more effectively. This results in a bulb that lasts far longer than its halogen forebears, whilst also consuming a fraction of the power.Though it is intended to directly retrofit to your existing installations, this 12V MR11 will require a compatible LED driver in order to work on main voltage circuits. Once fitted, it can potentially reduce your lighting bill by up to 90%.
