A multi-color spotlight has a lens on a first side, a rotational mechanism, a knob for actuating the rotational mechanism, and a power supply source within a housing operably coupled to the rotational mechanism. The rotational mechanism has a rotatable rod having a plurality of substrates coupled around the circumference thereof, each substrate having an LED chip mounted in the same vertical geometric plane in relation to the other LED chips, and wherein only the LED chip that is positioned directly beneath the lens is configured to receive power from the power supply source and illuminate.

Electrical switch assemblies are described which include multiple switch bars. Each switch bar provides both physical and electrical separation between adjacent electrical components. Also, described are battery powered devices using the switch assemblies. Examples of devices using the switch assemblies include flashlights and remote control devices. The devices and switch assemblies avoid parasitic battery drain.

A luminaire including an LED light source, a plurality of color filters, an optical device, and a control system is provided. In response to receiving an optical device setting value via a data link, the control system moves the optical device according to the setting value; calculates a numeric value for a color change associated with the optical device setting value by calculating a position change value for at least one color filter, the position change value based on the optical device setting value; for the at least one color filter, calculates a modified color filter position based on the position change value and a current color filter position of the at least one color filter and causes the at least one color filter to move to the modified color filter position.

The chainsaw guide includes a guide head having two independent spherical eyes that each support a light emitter. The spherical eyes can be manually adjusted within the guide head to space the visible light markers projected onto a work piece from the light emitters at select distances and orientation from one another. The guide head houses the internal electrical circuitry to activate and control the light emitters. The chainsaw guide is powered by a remote battery pack.
