Crompton Lamps LED MR11 Spotlight 3.5W GU4 12V Cool White 30° (35W Eqv)


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.


  • Power consumption of 3.5W (Equivalent to 35W).
  • 280 lumens
  • 25,000 hour lifespan
  • 4 Year manufacturer's warranty
  • 4000K - Cool White

Crompton 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.

What doesn't our warranty cover?
