This useful set of lighting units - four of them - are each connected to a control-cum-battery unit, the battery being rechargeable. They are constructed from good quality alloy, and other materials for the bendy parts. They have a reassuring quality feel about them. A nice touch is that you can have the control unit engraved, say, with your initials.
Although I have not used any of the components "in anger" as yet, it is good to have a set of different lighting units for different purposes.
I had an older 2D Maglite for work and treated myself to a newer 3D one for home and I'm not disappointed in the slightest. Torch Direct even laser engraved a message on the handle for free! Thanks and a happy customer over here.
