Powerfull and easy to use ring light for a Canon 16-35mm lens.

This is for LED-Rings from China (search for "LED Ring White Angel Eyes").

You need:

• 12V power supply

• 1x 110mm, 130mm, 150mm ring

• Something to control the lights (a switch for example).

Power for mobile use: 3 rings will need about 500mA at 12V and full power. The battery/LiPo needed will be to big/heavy to fix it directly on the ring light (my opinion). I will design a belt module (for your belt or the camera strap) with a LiPo (4S or with boost-converter) and a Microcontroller for PWM dimming.
