The Interfit STR200 Strobies Pro-Flash 180 W/s Flash Kit with Li-Ion Battery Pack offers a powerful guide number of 196' at ISO 100 with the portability of a shoe-mounted flash unit. The included Strobies Pro-Flash Battery Pack provides the necessary power for the user replaceable 180 W/s flash tube. The Pro-Flash mounts easily to the camera via the hot shoe for standard operation and triggering. It can then be rotated from 0 to 270deg. and tilted from -15 to 90deg. for directing the light in any direction you need. Also, the light has a color temperature of 5600K for matching with other daylight balanced light.
At full power, the Pro-Flash One Eighty with recharge in approximately 2.5 seconds. It will be able to produce about 700 flashes from a single charge of the battery pack. If you don't need that much power, or want to save energy, you can adjust the power settings from full to 1/128 power in 1/3 stops for your specific requirements. The flash also includes a 4.5" reflector and a diffuser for getting the look you desire as well as a flash stand for off-camera use.
The included battery pack uses a rechargeable lithium-ion battery with a capacity of 4,500mAh. This is capable of being completely charged in about 3 hours and provides power for 700 full-power flashes when using the Pro-Flash and 1800 when using a speedlight. Using this pack with other flash units requires the use of an optional power cable specific to the flash model and battery pack.
