A lamp has a flexible stem having an inner end and an outer end, a light source on the outer end, a clip on the inner end provided with a jack, and a power-supply cable removably pluggable into the jack. This clip can be secured to a suitable support, such as a book cover or laptop lid, or even on a jacket lapel, belt, or bill of a cap. Once the clip is mounted in place, the flexible stem is deformed to direct the light emitted by the source, e.g. an LED, on the desired location. The jack allows the lamp to be connected to a transformer, a battery, or any suitable low-voltage power source.
