A portable lamp assembly includes a spine member, a first and second side panel rotatably connected to the spine member, and a pair of first and second tangent links prismatically and rotatably operably coupled to the first and second side panel. Each of the tangent links has a plurality of vertical adjustment positions disposed between an upper and lower portion. The spine member and the first and second side panels have at least one source of light connected thereto. The first side panel and the second side panel can be rotated between an open position to allow the sources of light emit light towards a target area and a closed position for storage of the portable lamp assembly. The portable lamp assembly is free standing in the open position to allow the portable lamp assembly to be used without any external support.

A dental light comprises at least one light emitting diode light source configured to produce a light beam and at least one collimating lens system situated to receive the light beam. The collimating lens system is configured to collect and collimate the light beam. The collimating lens system can additionally modify the beam through controlled diffusion or shape the beam using an aperture.

One embodiment of the invention relates to a light tower. The light tower includes a base, an extendible mast coupled to the base, a light assembly coupled to the extendible mast and electrically coupled to the battery pack, and an inverter configured to receive and convert a direct current power from the battery pack into an alternating current power. The extendible mast is configured to move between a lowered position and a raised position.
