A light-emitting product (for example, a flashlight) includes a first housing includes a light source for emitting light and a lens system that is adjustable in position relative to the light source. The second housing can be attached to the first housing and includes a power source for the light source. When the first housing and the second housing are attached, the first housing and the second housing can be moved relative to each other to adjust the position of the lens system relative to the position of the light source to focus the light from the light source.

Fuel cell

A battery cartridge comprising a housing and one or more primary (nonrechargeable) cells therein. The cell can be a single primary cylindrical cell, desirably a primary lithium cell having a voltage of about 3.0 volts. Alternatively, there can be a pair or plurality of such cells electrically connected in parallel within the cartridge housing. The cartridge housing of the invention has an elongated body with an elongated opening in its surface of sufficient size to allow insertion of one or more cylindrical primary cells therein. The housing can be provided with a disk partition which divides the housing interior into two or more chambers, one for each cell. The cartridge can have overall dimensions similar to that of lithium ion or other rechargeable cartridges used to power small size camcorders or digital cameras. Thus, the battery cartridge of the invention has particular utility as a replacement for rechargeable cartridges for such devices. When the cartridge has been discharged, the cells can be removed from the housing and replaced with fresh cells.
