For a fast, lightweight, and compact light, look no further than the Venture TTL-600 Battery-Powered Monolight from Impact. The Venture TTL-600 offers full support for Sony, Canon, and Nikon, allowing you to go fully mobile with your studio. Busy photographers can set up their monolight on a stand or hand it to an assistant, put the optional TTL transmitter onto their camera's hot shoe, and start shooting.
The Venture TTL-600 operates in two modes. The Quick Mode reduces your light's power to produce a short flash duration range of 1/455 - 1/19,500 seconds for a faster recycle rate of 1.2 seconds. The Power Mode allows you to increase the power output to produce a flash duration range of 1/380 - 1/18,500 seconds with a 3-second recycle rate. With a maximum of 600W/s output, this monolight provides an 8-stop power range control, which gives you a range of choices to achieve the exact shot you had in mind.
The proportional and independent modeling-light modes can both be set to Constant to be on continuously, or to Recycle Signal that turns off when the flash is triggered and turns back on when recycled. The adjustable 15W LED lamp allows you to adjust the lamp's brightness independently from the flash or proportional to the flash's output.
Weighing in at just over four pounds and measuring less than 9" in length, this monolight could be tucked into most backpacks if necessary. The Venture TTL-600 comes with a reflector, removable pistol grip, stand mount, battery, charger, PC cord, and an aluminum case with a nylon strap for added portability.
