We recommend Lightech's advanced LED Drivers when using Hunza® outdoor lights with the Cree 3 Watt MR 16 LED or our G4 LED Capsule 1.5 Watt. These compact yet rugged little LED Drivers are fully waterproofed so they may safely be used in exterior locations. The 3 watt Driver is suitable for any load between 1 and 3 watts and is remarkably compact (see OXO cube for scale). The 12 watt Driver is suitable for any load between 1 and 12 watts
