I wonder if it's measured from one end to the other in a straight line or if they measure the whole radius. From end to end in a straight line you would actually have more LEDs and surface area of the bar compared to a straight bar.
How do you guys with LED bars like them in the dunes?
For the dunes I have not seen any LED bars that throw the light out as far and wide as HID lights. Right now I am running the stock LED lights and a 4" HID on each A pillar. I want to add another light, but not sure on a LED light bar yet.
The curved ones would seem to spread the light out more.
