The EVE P-140 VW includes interchangeable 25- and 45-degree lenses, which makes it useful all in kinds of situations. The 25-degree lens is great for close-up applications, such as when you're lighting the same element you're hiding the fixture in. The 45-degree lens is ideal for when you need a tighter beam angle to maintain brightness at a distance. And the lenses are magnetic, so changing them is fast and easy.
