Common Electrical Lighting Questions

Common Electrical Lighting Questions:

Voltage, provided by a power source such as a battery, is what causes current to move. Voltage is the pressure from an electric circuit’s power source that pushes charged electrons (current) via a conducting loop. Voltage = pressure, and is measured in volts (V).


The forward voltage is the amount of voltage required to get current to stream across a diode. Forward Voltage is the ‘negative voltage’, used by the LED when it’s on.


In direct current (DC), the electric charge only moves in one direction. Electric charge in alternating current (A/C), on the other hand, changes direction regularly. A/C is capable of changing directions and voltage from higher to lower with the help of transformers.


A 0-10V control applies a voltage in between 0 and 10 volts DC to create a differing intensity levels. The other 0-10V control technique was developed for, as well as is utilized as, a standard methods for regulating fluorescent dimming ballasts. It is preferred for some drivers utilized for LED lights.


An electrical conduit refers to durable tubes and give a route for individual electrical wires. Electrical conduits may be made of steel, plastic, fiber, or discharged clay. The majority of conduits are stiff, yet flexible conduits are used of for some specific purposes.


An LED driver is a self contained power supply which controls the power needed for an LED or range of LEDs. The light releasing diodes are reduced power, lighting devices with a long life expectancy and low power consumption, hence the need for specialized power products. LED’s require a LED driver to manage the electrical current. They often look similar to a fluorescent ballast but are available in all shapes and sizes. Without the proper LED light driver the LEDs would become hot and unstable resulting in failure and poor efficiency. To ensure the LEDs work flawlessly the self contained LED driver is required to supply a continuous amount power to the LED.


They are usually described as dimmer switches. By utilizing the ability of a transformer to change the voltage going through a circuit, a light can be made brighter or dimmer. All transformers are sized to a rating of Volt-Amps. VA (Volt-Amps) indicates your power supply/transformer need.

There are 2 various designs of transformers to select from, either remote or surface mount transformers. Transformers can be broken down into 2 types: magnetic or digital transformers.
