The lamp is very slight, at least it does preocupe me at all especially for the use I have that is very moderate (nocturnal trips in the garden to get firewood, walks at dusk hours, etc.).
Side lighting, again, it looks to be heavy. The diameter of the circular beam is adjustable by means of a knob located at the lighting. It's very well thought out. The power appears to be at the rendezvous.
And to top it all: the ability to recharge the device using for that the mains cable or cigarette lighter provided.
This does nothing to spoil the pleasure of buying: the fact that the device is delivered with a box of good quality, solid, with one side closes through what seems like a small magnet.
At this price there is no hesitation, the price / quality ratio is really respected.
