Second, as I said above, I have just north of $90 invested in my 3 main lights and I have more flexibility and capability for that money than I do for the 850 I own. If I want, I can run all 3 lights for about 2.5 hours of night riding, run 2 and keep one in reserve or run one each and push my run time out to over 7 hours of night riding if I want. That's on high output. If I were to ride with them at the lower setting, I can go for 14 hours if I wanted. I could ride from dusk to dawn on the winter solstice if I wanted.

Just to get the same run time and light...which is more important to me... on the 850 for my regular 2.5 hour run time, I'd need to spend another $180 on 2 headlights as well as 3 extra batteries at $45 each. That's a total investment of over $400 and, I have to fiddle with changing batteries possibly in the dark.

Let's see, $100 invested vs $400? Which is the better deal?
