Low voltage lamp (10) for external use, comprising: •—a hollow and sealed container body (31) consisting of at least two opening half-shells (11.1), filled with insulating gel (G) and containing a terminal connection block (12); •—at least one light source (L) having at one of its extremities at least one electrical and mechanical connection means (13) which is electrically branched by means of electrical wires (25) with respect to said block (12); wherein at least said wires (25) and at least one portion of said connection means (13) are housed in a sealed manner in said container body (31) by means of said gel (G), which encloses them like a cast, and wherein said gel (G) is configured to model its shape on said wires (25), said block (12) and said at least one portion of said connection means (13), in a reversible manner.

A support base includes a connector hub having a top end, a bottom end spaced apart from the top end, and a chamber wall extending between the top and bottom ends. The chamber wall defines a chamber within the connector hub. An interface may be positioned in the chamber. The interface is dimensioned such that a support gap is formed between the interface and the chamber wall. The support gap may be dimensioned for receiving a wall of a support structure having a hollow interior into which the interface is received.

A support base includes a connector hub having a top end, a bottom end spaced apart from the top end, and a chamber wall extending between the top and bottom ends. The chamber wall defines a chamber within the connector hub. A power interface set may be positioned in the chamber. The power interface set is dimensioned such that an annular support gap is formed between the power interface set and the chamber wall. A cover plate may be coupled to the top end of the connector hub.

A battery pack for electrically coupling with and securing to a portable electronic device having a device connector and one or more user interface components includes an electronics section and a latch section. The electronics section includes a battery compartment configured to hold one or more batteries and a connector mechanism configured to interconnect with and form a waterproof seal around the device connector. The latch section is pivotably coupled to the base portion and configured to pivot relative to the base portion to transition the battery pack between open and closed states. In the open state, the electronics section and the latch section form an open frame structure configured to enable installation of the portable electronic device in the battery pack. In the closed state, the electronics section and the latch section form a closed frame structure configured to secure the portable electronic device within an opening defined by the closed frame structure.
