The Snap Shot LED is part of American DJ's continuing pursuit for creating high quality affordable fixtures. The Snap Shot LED is a simple, small LED strobe. This strobe is lightweight and compact which makes it a great piece for mobile DJ's, architectural lighting, or lighting effect. The flash speed can be adjusted using the knob on the rear of the unit. There are also IN/OUT mono plugs located at the rear. These plugs are used to connect to other Snap Shot LEDs.
