A sacred light

It's true that it illuminates super strong headlamp with adjusting the concentration of the beam at the front and the microscopic switch-on button above the optical unit that I do not find convenient, especially with gloves for example. Another black spot; the battery box placed at the rear which incorporates a dimmer that seems a bit superfluous at that. I bought this lamp to knock on and under my car. The concern is that when I'm lying below and the box rubs on the ground which is not good for his life or for my neck because, suddenly, I am obliged to remain tight to prevent blow the damn box does not rub the ground and especially to avoid me constantly reset the dimmer otherwise field light not see anything as it moves (the drive) moving on the ground. Otherwise, apart from these few flaws, it is a very powerful lamp and it changes me of my old car purchased in large area although they had their batteries in the lamp block which is more convenient.
