Disclosed is a compact portable light tower that can be stacked or nested. The light tower employs a scissors lift mechanism to raise a set of bar lights from a housing having a height of about 28 and a length of about 60, to an extended height of about 360. The scissors lift is extended and retracted by use of a linear actuator. Batteries or an engine/generator assembly is employed for operation of the actuator and light bar. The housing can be stacked for ease of storage and transportation. Outriggers provide stabilization of ground engagement.

A charging process of a rechargeable lighting device is controlled by a software algorithm and a microcontroller configured within the rechargeable lighting device which has first and the second charging contacts located on its exterior and the charging circuit is turned on when a cradle detection circuit detects that at least one of the charging contacts engages an electrical contact when the rechargeable lighting device is inserted into a charging cradle. The charging process begins with a charge-current which is constant and a battery charge-voltage which rises up to a nominal battery charge-voltage. The rechargeable lighting device recovers to a preselected condition through use of a power interruption avoidance algorithm configured within the microcontroller when there is a loss of power to the microcontroller of less than a preselected amount of time.

Provided are wearable lights or lights that can be attached to accessories when carrying out activities in low-light or no-light conditions. The wearable lights incorporate a portion of non-magnetic material with an internal chamber with a low friction internal surface that is surrounded by a copper coil. A magnet is passed through the internal chamber, allowing the copper coil to break the magnetic fields of the magnet, which creates a burst of electrical current. The current is used to emit light through LED's. Movement of the wearer/user generates the movement of the magnet in the internal chamber, and repelling magnets at the top and bottom of the internal chamber assist the magnet in moving back and forth through the chamber. The inventive device can be adapted for use in many sporting and other applications, such as in running shoes, running belts, rucksacks and as stand-alone wearable lights.

A flame simulator can include a light beam source, a range limiter, a light beam mover, a power supply, a power control circuit, and a flame screen. The light beam source can be adapted to project a movable beam of light with a circular, oval, elliptical, or otherwise round, cross-sectional shape and with an intensity, shape and/or color that mimics a flame (e.g., a candle flame) when the beam strikes the flame screen. The light beam mover can generate beam movement and the range limiter can limit the range of movement so that the beam stays mostly on the flame screen in a region bounded by the typical range of movement of a flame being simulated (e.g., a candle flame moving in response to ambient air currents). The light beam mover can cause the illumination provided by the beam to dance on the flame screen with variations in position and shape that mimic a dancing flame (e.g., a candle flame being blown about by air currents). One or more of the flame simulators can be incorporated into an imitation candle.

A stackable enclosure for support of a mast stored in horizontal position and rotatable to a vertically deployed position. The enclosure employs a housing have sidewalls constructed and arranged to support a plurality of stacked enclosures. The dimensions of the enclosure with wheels can allow for the transporting of thirty units on a single 48 drop deck trailer. The enclosure has a hinged lid to allow ease of access to the interior which can house a power system to operate a bank of lights. Outriggers positioned along each corner of the enclosure provide stability to the mast in high winds. A hinged axle can be used to pivot enclosure wheels upward, allowing the enclosure to rest flush on a trailer deck or ground surface.

A portable heater system including a pressurized air source, adapted to convey ambient air through an electric resistance heater, to provide heated breathable air, and a controller adapted to control the electric resistance heater and the pressurized air source. A generator, driven by an internal combustion engine may be provided to power the electric resistance heater and the pressurized air source. The portable heater system may be embodied in a light tower.

A combination flash light and work light. The device can also be provided with a USB receptacle port for electrically connecting a cable to recharge the internal battery or using the internal battery to charge another electronic device. A plurality of light array panels can be pivotally secured to the main light unit. The main light head can also pivot with respect to the rest of housing where the electrical circuits and components are housed. A relatively large or wide base can be provided at a bottom end to allow the device to be freestanding. A magnet and/or hook can be provided at the base to permit the device to be hung to an object or secured to a metallic surface.

A combined flashlight and lantern can have a light powered by a metal-air fuel cell that runs, or is activated, by water or an electrolyte such as salt water. The combined flashlight and lantern has both flashlight and lantern configurations. In the flashlight configuration, a head with a distal concave reflector is disposed towards a handle with the light in an aperture of the distal concave reflector to direct light axially. The distal concave reflector is opaque to resist light from emitting laterally therefrom. In the lantern configuration, the head with a distal convex reflector is disposed away from the handle and opposing a proximal convex reflector to direct light radially.
