Bob I got to tell you, I needed to take the guide on's off my boat trailer. I had my light hooked to the boat battery 15 Min. after it came out of the box. I got under the boat and laid the light beside me, I had all the light I needed to un'-bolt those guides. That little thing is really bright for it's size. I can't wait to get out night fishing with it. I'm impressed and happy with it so far, makes a heck of a trouble light...Thanks...Crappie 1
