The Data Doctors recently did a review on the Westcott Ice Light. They highlight each of the products features as well as show the Ice Light in action.
As for durability, this thing (Ice Light) is built like a tank!
The Ice light is a portable handheld daylight light source that is fully dimmable. The Ice Light allows photographers a portable option if there is limited space to setup an entire photo studio. If you don’t have an assistant, the Ice Light is easy to mount, with a built in 1/4 – 20 thread on both sides. The beauty of continuous light is that you can see how light patterns fall before the shot, therefore eliminating the test shot and creating a better workflow. Another great perk of being continuous light source, means that it has multiple uses including photography and videography.
