A multi-spectral flashlight includes a housing, a battery disposed in the housing, a power switch, a LED module including a plurality of LEDs which emit different colors of illumination, a LED driver coupled to the LED module, and an alternate illumination selector switch coupled to the LED driver. The LED driver is configured to drive the LED module in a default illumination mode in response to a first user operation of the power switch and a selected alternate illumination mode in response to a second user operation of the power switch. The LED driver is further configured with a plurality of selectable pre-determined alternate illumination modes which include different colors of illumination. The LED driver advances through the plurality of selectable pre-determined alternate illumination modes in response to operation of the alternate illumination selector switch, allowing selection of one of the plurality of modes as the selected alternate illumination mode.

A fan-shaped flashlight with adjustable lighting angle includes a connection seat disposed at the front end of a handle, a front-projection primary light installed at the front end of the connection seat, and two left-front and right-front projection secondary lights pivoted to two sides of the primary light respectively. The primary light and two secondary lights are arranged side-by-side on the same plane to project light within a fan-shaped angle, and the two secondary lights can be turned separately towards the outside relative to the primary light to adjust their lighting angle and position.

The present invention discloses a telescopic LED grow light, which comprises a power supply box, a power supply holder, a plurality of lamp bodies and a telescopic frame, wherein the power supply box is located in a middle of the LED grow light, two power supply holders are respectively fixed at both ends of the power supply box, the power supply holder is also used for fixing the lamp bodies located at both sides of the power supply box, and the lamp bodies are fixed by the telescopic frame for expanding or contracting. The present invention has the beneficial effects that the PPFD value is changed by adjusting the telescopic function of the grow light. The function of the grow light that can be retracted and reduced for storage is very practical, in addition, it is also convenient for transportation after contraction.

A portable lighting apparatus includes a handle, a light head pivotally coupled to the handle through a plurality of positions via a joint, a battery receptacle supported by the handle, a first light source supported in the light head, a second light source supported in the light head, and a user interface supported by the handle and configured to be selectively actuated by a user to operate the first light source and the second light source. The battery receptacle is configured to receive a rechargeable battery. The first light source includes a laser selectively operable to emit a single light wavelength, and the second light source includes one or more LEDs selectively operable to emit a distribution of light wavelengths.

A multi-purpose, hand-held flashlight has an elongated body with a front body portion having a bottle opener and a front engaging structure. The elongated body also includes a rear body portion with a rear engaging structure that is cooperatively dimensioned to interact with the front engaging structure to releasably couple the front body portion to the rear body portion. The rear body portion includes a second substantially cone shaped extent that includes a recessed cutting element. A lighting element assembly is disposed within the elongated body and includes a lighting element printed circuit board coupled to an emitter assembly, a power source, and a switch. The switch is configured to change the operational mode of the emitter assembly. An attachment mechanism is coupled to the second extent of the rear body portion.
