This is a limited experience with this light as *4 and *8. Frankly I could barely tell the difference in LIGHT output under most real world experience ways I tested it. I could tell the *8 got hotter and used up battery faster. I got them mixed up and had to look at the driver to count chips to even figure out which was which. I started this thread because I didn’t get an answer out of the current thread. IMO *8 is wasted on a light of this type.
