I use my lights at work and don't mind changing the batteries everyday. I use them to look inside of weldments, work within 20 feet. Brightness is important, but I don't want the blinding brightness of the P7. Between the Lumens Factory 3.7v special, Malkoff m30, and the Dereelight, how do they rate in terms of perfermance in this order:
Brightness
Beam quality (both tint and smoothness of beam [lack of rings])
Runntime
Throw
Also, is the Malkoff really worth the $55? I don't fully understand what makes a Malkoff different (I know it has some kind of lens). Does the Malkoff shine a nice beam? Does the Lumens Factory have a nice beam?
