I’ve loved the M18 ever since I first got to use it! I had heard people say that the M18 has he same light at a 4k HMI, so when I heard that High Output had a new M40 in town from MA I decided to give it a test. With Greg’s help, I was able to use my light meter and test the levels of both lights in spot and flood. Check out the results below.
