I just thought I'd put my 2 cents in.....
All that I have read here concerns small, light weight, very brite flashlights.
I work for the RailRoad & I inspect RR passenger cars for a living. I do the Daily CDMI (calender day mechanical inspections) every night,year around, in all kinds of weather. 1,000s of peoples lives depend on me qualifying a "safe train" for morning service. Being the Senior Car Insp. one of my jobs is to train the new car insps when they are on "OJT". I tell them, "get your light, and let's go walk some trains"...
I have seen EVERY possible light come out of thier tool bag over the years!!! Simply put, they just don't git it done..... Batterys die anywhere from 10 mins to 2 hours into our inspections. A light starts out bright as day, and is pretty much giving up the ghost & dim as a nightlight by the time we get around the train & back where we started. When I want a light... I want a LIGHT!!!!!
I use a 6volt Heavy Duty hand lantern. I get them for free, and the batteries too. I get at LEAST 3 weeks out of a 6volt battery & usualy change my battery the 1st of every month. By then, It's starting to get noticably dim. After the trainees use my lantern for awhile, they soon get one of thier own!!!
I have a 6volt lantern that I bought, in my truck. If I need a light to track a deer, I back out, go to my truck & get my lantern. I want a light that lights up the woods!!! With a beam that will easily shine 50yds or more!!!!! You can NEVER have "too much" light...
Just one Old Woodchucker's opinion.....
