Intended for use in an array of domestic and commercial settings, this MR11 spotlight from Integral LED employs four SMD LED units and an anti-glare refractor to produce a light akin to 35W 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.Features:Power consumption of 3.5W (Equivalent to 35W).280 lumens25,000 hour lifespan4 Year manufacturer\'s warranty4000K - Cool WhiteCrompton 12V LED MR11 lamps will operate with most AC or DC 12V transformers. However, some 12V transformers may have a minimum required load which may not be met when installing low powered LEDs. These transformers may cause flickering or the LEDs not to function correctly.
