1. A device comprising:
an upper housing of a nail lamp comprising a portion having a translucent material;
a lower housing, coupled to the upper housing, wherein an enclosed space is formed between the upper and lower housings;
a display panel capable of displaying at least two digits;
a first printed circuit board, positioned in the enclosed space between the upper and lower housings, wherein the first printed circuit board comprises electronic circuitry comprising a control circuit that is coupled to one or more buttons, accessible from an exterior of the nail lamp, and the display, and
a second printed circuit board, coupled to the first printed circuit board in the enclosed space between the upper and lower housings, wherein the second printed circuit board comprises a plurality of interior-illuminating light emitting diodes that are surface mounted on the second printed circuit board and coupled to the control circuit of the first printed circuit board,
light emitted by the interior-illuminating light emitting diodes is directed through apertures into a treatment chamber of the nail lamp, and
when on, the interior-illuminating light emitting diodes emit ultraviolet light; and
a plurality of exterior-illuminating light emitting diodes, coupled to the control circuit of the first printed circuit board, wherein light emitted by the exterior-illuminating light emitting diodes passes through the translucent material and is visible from the exterior of the nail lamp
an internal rechargeable battery pack, coupled to the first printed circuit board, wherein the rechargeable battery pack comprises a USB port and a battery gauge; and
an exterior power connector, coupled to the first printed circuit board, wherein power input via the exterior power connector is used to power the electronic circuitry of the first printed circuit board, interior-illuminating light emitting diodes, and exterior-illuminating light emitting diodes, and to recharge the internal rechargeable battery pack.
