It has power settings from full power down to 1/128 power. I have updated it to the latest Firmware 2.2.The Modus 360RT is supplied with its own battery, charger and USB cord. The flash cycles quicker than a standard flash with normal batteries. It also has a built-in video light with adjustable brightness, so if you shoot video as well as stills you are covered. The Viper TTL has a wireless range of up to 100m (conditions dependent) and requires 2x AA batteries (not supplied). You can adjust the output of the Modus 360RT with the Viper - so you don't have to keep wandering back to adjust the brightness.
I have updated it to the latest Firmware 2.5. You can find manuals for both on the Hähnel website, but one for the 360RT is supplied. The units are already paired (you can re-pair should you wish) so pop a couple of batteries in the Viper and you'll be shooting off-camera flash within a few minutes. The photos show the actual items for sale. The Playmobil figure is not included in the sale.
