This Round USB White LED Lamp features 5 LEDs and is designed for low power lighting such as desk lamps or torch lights. Its discreet size and circular layout make it a great choice for creative lighting enclosures. The board is designed such that it is within the supply rating of a computer USB port (under 100mA) - Micro-USB cable required. This means you can power it conveniently from a computer/laptop or a suitable 5V power supply. The PCB is designed to fit inside a 28mm square area with the switch positioned prominently so it is easy to access. In the centre of the board is a single M3 mounting hole. The 5 LEDs are evenly set on a 72°degree separation from each other, from the centre mounting hole. The onboard switch can be used to turn on/off the LEDs. An additional switch can be connected in parallel with the PCB switch to allow remote mounting within an enclosure. When using a remote switch the PCB mounted switch should be left switched to ‘Off'.
