30w Plug & Play LED Driver LED lights run at a lower voltage than most of your mains lighting fixtures. A typical LED light runs at either a 12v or 24v rating, which is far lower than the 230v of your mains. Thats why LEDs like your decking lights need a transformer or a driver to supply your lights with the correct voltage they need. Connecting your lights to the wrong voltage can damage your fixtures and cause problems like flickering, premature failure, or irreparable damage. This Plug & Play LED Driver has a 30w maximum load , meaning it can theoretically have 60 0.5w decking lights connected to it all at once.
