This Dynalite RK4-1222 Road 400W/s 2 Head Kit is powerful and versatile enough to handle a wide variety of on-the-run assignments like fashion, corporate work, portraiture, weddings and interiors. The RP400 pack has 3 head outlets and breaks down its output symmetrically or asymmetrically over a 6 stop range with short flash durations at a super fast 1.0 seconds recycling time at full power. A variator knob allows fine tuned exposure adjustments over 2 stops in 2/10 stop increments. Triggering options include sync cord (provided), IR or optical slave.

The included MH2015 flash heads have a 250W modeling light, 16' power cable, user replaceable 2000W/s capacity flash tube and an ideal color temperature of 5400K. Fan-cooling means that you'll get extended life out of both the flash tube and modeling lamp. The kit's stands and umbrellas employ a unique design that lets them fold in upon themselves to fit in the sturdy Cordura case.

Although you may be tired at the end of a long shooting day, it won't be because of your equipment. The RP400 pack weighs a mere 4.1 lb and the MH2015 flash heads about 2 lb each.

        I use this for my high school photo classes. It is easy to use (and to teach others how to use) and set up. The all-in-one bag makes it easy to move around and store.

            Comments about Dynalite RK4-1222 Road 400 W/s 2 Head Kit:

            Not happy with the overall feel of this package. Can't unplug cord from flash heads. Power cord would not stay in and when bumped or moved it would stop working. Stands and umbrellas seem very poor quality, light (as you'd want) hollow and unsmooth set up.
