This LED Transformer / Driver is used to power low voltage (12v) LED bulbs and strip lighting. LED bulbs require a constant current to work properly. Sometimes a normal 12v transformer will work correctly with LED bulbs, but in some cases the lifespan of the bulb will be reduced. This LED Driver is the perfect product to replace the 12v transformer which is currently powering your existing low voltage bulbs. All orders at LED HUT have a 30-day hassle-free returns and 5-year warranty our bulbs are made from the best quality components so we can give the longest warranty on the market. If this product isn’t suitable, take a look at our complete LED Transformer range.
