An LED transformer/driver is used to power low voltage (12v) LED panel lighting. LED lighting requires a constant voltage to work properly. If you\'re using a non-LED compatible transformer, you may experience flickering, buzzing or reduced lifespan of your bulbs. DALI stands for ‘Digital Addressable Lighting Interface’ and is an industry standard that allows the seamless mixing and matching of components regardless of the manufacturer to give you complete flexibility. This particular transformer is suitable for when you\'re using dimmable panels. Please contact us if you’re unsure on compatibility.
