The Boltzen 150W Fresnel Focusable LED Daylight from CAME-TV features an adjustable Fresnel lens to help focus the lights. When used without the lens the light becomes a wider flood, and the included barn doors help to control the spill. This allows you to go from a tight spot to a wide flood all in one continuous light. The filter set includes soft, milky-white, and orange filters that can change the color temperature to match an existing setup or create a specific lighting look. The dimming knob can steplessly adjust the brightness as per the users' need.
