The light is dimmable from 0 to 100%, and while you can make light intensity adjustments locally on the fixture, you can also make them via Bluetooth with your smartphone and a free app. The 100d has eight built-in customizable effects, an umbrella mount, and a Bowens reflector mount for access to Amaran light shapers and also those many other manufacturers that use this popular mount. The 100d is ready for worldwide use via its built-in 100-240V power supply, but it will also run on optional batteries when AC power is unavailable.
