Anyone who is a video or still photo professional will tell you how great Dedo lights are. Compact versatile and tough, these would have to be the best and most used lights in out kits. The quality of light is superb and even and the fact that they can be dimmed and have a focusable spot to flood range of about 20 to 1 makes them well worth the asking price, which by the way is not cheap, www.barbizon.com.au sell the DLH4 150W for about AU$780.00 here in Sydney Australia. Here is a great video that contains interviews with photographers and cinematographers on why they love these great lights. Keep an eye out for when they dunk them in water while they are on!!
