Selecting the Best LED GU10 Halogen Replacements

Replacing your low-voltage MR16 or GU10 halogen bulbs with dimmable LED GU10 spotlights will save money on your power bill, reduce your carbon footprint, and give you a product with a longer life. The following guide aims to help you become more energy efficient.


 In this guide we’ll help you:

  • Quickly establish the wattage comparison between Halogen and LED GU10’s.
  • Understand whether your existing fittings will work.
  • Establish whether you need a new dimmer switch.
  • Choose between our top selling dimmable and non-dimmable GU10’s.

Wattage Comparison Table

Naturally, you want your new LED GU10 spotlight to give you the same bright light as your existing halogen GU10 bulb. In the early years of LED, light output was questionable, but due to advancements in technology, it’s fair to say that you can expect pretty much the same Lumen output from your LED’s – without having to break the bank either.

 Here is an at-a-glance table that shows the equivalent LED GU10 wattage:

Halogen GU10


30w 3w
40w 4 - 6w
60w 6 - 8w
75w 8w
100w 12w

Can I replace like-for-like bulbs?

The quick answer is yes - the longer answer is it depends on a) the bulb type and b) whether you are currently using a dimmable halogen circuit and switch.

 Most non-dimmable GU10 Halogen bulbs can be easily replaced with an equivalent GU10 LED as electrical current conversion happens at the bulb. Only certain bulb types do not do this and may need additional drivers to convert the AC current to DC.

Please call us or speak to a qualified electrician should you wish to clarify which bulbs these are or have any concerns you are fitting a bulb which may not be compatible with your existing fittings.

“We regularly update older halogen downlights with new LED downlights. We recommend clients do not overly rely on one form of lighting such as downlight and neglect other forms and positions of lighting.”
