Abstract
A sleeve for a portable light may comprise: a hollow sleeve for surrounding a source of electrical power and having a plurality of elongated longitudinal spring members. Only one end of each spring member is connected to a wall of the hollow sleeve and an opposite end thereof is free. Each spring member is formed to partly extend radially outward of the hollow sleeve and to partly extend radially inward of the hollow sleeve toward a source of electrical power that may be disposed therein. The hollow sleeve may be disposed in a portable light that may include a housing, a light source and a source of electrical power that may reside in the sleeve.
