They are great, your going to be a happy camper. All the rest of your lights will seem dim. Congrats on a great purchase. You will use it for 10 years or more.
Went out last night and shined everything over a 20 acre spread. The cows seemed most appreciative. I am impressed! I have never had the opportunity to even handle an M6 before so WOW. I lovingly carried it for over an hour before I headed back inside. Great feel and balance to this light. I'm totally broke now so lucky for me I am happy with the purchase.
