The 9 Watt AC DOB (Direct on Board) Led PCB is a very compact high performance and high brightness driver onboard led PCB, It’s actually the same PCB that we already have inside the Led bulbs which we use in our home. As the name suggests it carries its driver on Board so it doesn’t need any external driver to run, just plug in the AC voltage and you are good to go. Its Connection is also very easy to do, with just two terminals N and L you can power up this PCB and use it to light up your rooms. This module is just the led PCB it doesn’t come with Led Bulb fixtures. Led on Single PCB: 20. Input Voltage:- 220V. Power Rating: 9W. Max Input Voltage:- 240v ( More than 240v Voltage will completely damage the product ) The heat sink is on the backside of PCB, But to efficiently despite the heat from the PCB an external heat sink plate is required
