I bought one of these as I am liking LED lighting more and more for their durability, long life and cool running temperatures. As soon as this arrived, I saw its potential and ordered another one straight away. The light at full power is incredibly bright and the dimmer switch is a great feature. One light at full power is enough to light up our average sized garden at night.
I have so far used these lights for both stills photography and videography and they work very well. To get a pure white background for video work, it can be tricky but in my office, for quick intro video clips, I have the following:
A white sheet on the wall, 4 builders' halogen lamps (£7 each) with strong clamps attached to a couple of stands which illuminate the background, and the CN-160's to light me and it works perfectly. Of course, you need to adjust camera settings but as a quick, home office set up, these LED lights work brilliantly.
For the money, they are a handy piece of kit to have around whether you shoot video or stills...
The only reason I gave these a 4 is for the fact that the construction is a little "cheap" but then again, so are the lights so this is a 5 star product in a 4 star housing!
