Light-emitting diodes (LED) are PN junction devices that give off light radiation when biased in the forward direction. LEDs are used in a wide variety of indication applications

LED lamps are light emitting diode arrays with traditional lamp ballasts

Lamps are light sources that emit incoherent light for illumination. There are many different types of products. Examples include fluorescent lamps, halogen lamps, heat lamps, incandescent lamps, LED lamps, projection lamps, spectral lamps, and stage lamps. Specialized and proprietary lamps are also available

High intensity discharge lamps (HID) contain compact arc tubes, which enclose various gases and metal salts, operating at relatively high pressures and temperatures. HID lamps are often used as UV light sources

Toggle switches are actuated by moving a lever back and forth to open or close an electrical circuit.

Color sensors register items by contrast, true color, or translucent index. True color sensors are based on one of the color models, most commonly the RGB model (red, green, blue).

Battery chargers are devices for charging rechargeable batteries.

Scales and balances are used to measure static or dynamic loads for a wide range of industrial applications.

LED mounts and lenses are used to mount LEDs and shape or transfer light output. Other components in this area include LED light pipes, headers, interconnects, and assemblies

Digital LED displays are segmented or dot matrix displays allowing for numeric only and alphanumeric character representation

Message LED displays are typically commercial or industrial signs. They allow for larger characters and longer viewing distances than their smaller digital cousins

Lighting fixtures and lamp sockets produce artificial light in industrial areas or workspaces, and mechanically hold and electrically connect lamp bulbs to wiring

UV light systems provide ultraviolet light for identification, tracing, curing, disinfection or processing applications

Illuminators are used to provide adequate contrast for imaging. Illuminators include backlights, LED illuminators, and fiber optic illuminators

Warning lights provide a visual indication of a hazardous situation.
