Product that does not disappoint: beautiful lamp, solid, well illuminated. But beware: sold with lithium batteries, light and powerful, but expensive ... You can put alkaline batteries of course, but the torch does not accept low voltage. The batteries are quickly discharged by the powerful lamp and voltage quickly drops below 1.5V. We can not use NiMh batteries (1.2 V) as with other LED torches cheaper and equally powerful: the lamp refuses and better flash. Despite its shape, the head does not focus.
