At 600ws the Rovelight can blast out plenty of light at full power and although the power can only be adjusted in 1/3rd stops but it does go all the way down to 1/128th power. The power settings are controlled and displayed on the rear LCD which also has all the usual controls you’d expect on a studio head although they can take a bit of getting used as the buttons are small and many are multifunctional. Thankfully the remote trigger can also change the power and trigger the flash for test metering too
