The Polaris series light bar feature Cree LED bulbs and 5D reflectors in the lens to project the light both further and at a wider angle. The 5D lens also works as a fish eye lens which magnifies the light from each LED chip giving better light spread and a better light pattern overall. The 5D reflector is far superior than the older 3D reflectors found in most bars.
The 23" Polaris is a great bar if space is a concern. The brackets are adjustable along the length of the bar which makes it ideal for a wide range of applications on your 4x4.
