Rather than being shipped from China, the High Efficiency range is made in the EU, and therefore reduces associated carbon miles considerably. The High Efficiency range also features our new high efficiency LED modules which deliver efficiencies of up to 150 luminaire lumens per circuit watt. This means they can reduce the lighting energy consumption by up to 50% compared to a standard LED spotlight! So, if you're using a 20w spotlight you can now get the same output from our High Efficiency 10w version.
