Crompton MR11 Spotlight LED Light Bulb GU4 3.5W (35W Eqv) Cool White 30°

  • Cap type: GU4
  • Power Consumption: 3.5W
  • Equivalent: 35W Halogen MR11
  • Colour Output: Cool White
  • Dimensions: Diameter=35mm Height=40mm

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.

Here at SimplyLED, we want you to be able to buy with confidence both in ourselves and the products we sell. With this in mind, a number of our bulbs carry a specific warranty that ensures you can do exactly that.

What doesn't our warranty cover?

In any instance where your bulb has developed a fault, we will do our utmost to replace it or offer a full refund (provided the item is still within its stated warranty period). However, if it becomes apparent that the product has been misused, tampered with or modified in any way, we will view this as having voided its warranty.
