With me, he changed from a MAG-LITE 2D with conventional lamp. Background is that I wanted to reduce the power consumption / needed because the lamp in the evening always go for a walk with the dog is used and the conventional technology had a frequent battery changes result.
After switching to LED I nu changed no more batteries and the light output of the flashlight is sublime, no doubt since about half a year. It radiates to worlds beyond the conventional 2D lamp and focusing is also much easier and better terms of quality. I especially like that the halo of the flashlight is cut off outside sharp. The advantage for me is that I can illuminate the dog indirket with the limit of the direct light. Right in front of him So I can not hide him on the one hand and, secondly, (the bigger advantage) he does not chase its own shadow over the yard;)
For quality of MAG-LITE I have to think I have nothing further mention. Simple principle, which has been perfected, robust materials, waterproof ....
It should be mentioned that there are also better lamps from other manufacturers. For example, a friend of mine has a LED Lenser, who once more coverage and better focusing, but it costs about twice as much. Therefore, this MAG-LITE is the first choice in terms of price / performance for me.
