This superb lighting kit from Interfit proves that creating beautiful, flattering studio lighting is not difficult and it doesn't have to be expensive, either. With 3 studio flash units, a muslin background and padded storage bag, it's an ideal setup for advanced home or location lighting situations. An instructional DVD is included to help you create perfect lighting right from the start. Unlike most flash kits in this price range, the EX150 includes a soft box, a lighting accessory favored by most professionals because of the soft and controllable light it creates. Combined with the white umbrella on the other flash, the 3 lights in this kit will produce soft and flattering light for portraits, still life shots, internet auction and other product shots, and more. The Mark II builds on the strengths of the original EX150 and features a redesigned flash housing with easy-to-adjust controls, more power, a brighter 100 watt modeling light, and a user-changeable flash tube. All add up to make a great lighting value even better. EACH EX150 MARK II FLASH FEATURES: 150 watt/second with ISO 100 guide number 96; continuously adjustable power from 1/8 to full; 100W modeling lamp; fires via PC cord, test button and built-in slave sensor; low 5 volt triggering circuit, safe for all types of cameras.
