This compact LED measures 13 cm long, is as flat as a smartphone and can be camera hotshoe or tripod mounted via an adapter or ¼-inch thread base. With variable colour temperature settings (3000-5000K) it can match the ambient lighting or add a special mood to any scene. Push button controls provide access to control the power output and colour temperature and read them out on the OLED display. Powered by a built-in lithium ion battery with a micro USB interface, the S500 BC comes with an easily mounted diffuser with a spacer that allows the photographer to soften the light source.
