What's the difference between 40° and 180° optics?
There have been many people asking: what's the difference between the 40° and 180° optics? Is one brighter than the other? The short answer is no, neither is brighter than the other. However, depending on where the light is being looked at from determines where it is brighter from. The 40° modules will be seen the brightest from farther down the road. They are made for long range visibility. The 180° modules give a wide range spread. This makes them brighter from up close, but for 180° around the light. A perk of the Feniex Fusion line is you get to choose! For lights with more than one module, you are able to customize them with 40° modules, 180° modules, or some of each.
