Contactors are heavy-duty electromagnetic switches that are normally used in controlling large lighting loads and motors. They operate similar to relays, but often times deal with more voltage, higher amperage, and have more input and output options. Read More
The Kelvin Scale is used to talk about color of objects at certain temperatures, whereas other temperature scales deal with actual heat or thermal temperature. Kelvin is used in lighting especially for that reason, to talk about the color of light emission. Read More
A relay is a type of electromagnetic switch, similar to a contactor, that can be controlled remotely with electricity, rather than needing manual input as a standard switch would. Read More
