What Are 347-480 Volt High Bays?
347-480V high bays refer to high-intensity lighting fixtures that are designed to operate at voltages of 347-480 volts. These high bays are typically used in commercial and industrial settings, such as warehouses, factories, and large retail spaces, where high levels of illumination are required over a large area.
The term "high bay" refers to the height at which high bay fixtures are typically installed, which is usually between 20 and 40 feet above the ground. They are often used to replace traditional high-intensity discharge (HID) lighting fixtures, such as metal halide or high-pressure sodium lamps, which are less energy-efficient and have a shorter lifespan.
347-480V high bays are typically powered by three-phase electrical systems and require specialized wiring and electrical connections. They are available in a range of sizes, wattages, and lumen outputs, depending on the specific application and lighting requirements. Some high bays may also come equipped with features such as dimming controls, motion sensors, and programmable lighting schedules to help save energy and reduce costs.
What Are 277-480 Volt High Bays?
Similar to 347-480 volt high bays, 277-480 volt high bays are also considered “high voltage.” The difference is that 277-480 volt high bays can operate within a wider range of voltage input. The 277-480 volt high bays are suitable for use in high-voltage electrical systems, which are commonly found in industrial and commercial settings. They are designed to provide reliable and efficient lighting in these environments, while also being durable and able to withstand harsh conditions such as high temperatures, moisture, and dust.
High Voltage v.s. Low Voltage
High voltage refers to a higher level of electrical power than low voltage, usually measured in kilovolts (kV). High voltage is used in a wide range of applications ranging from electrical transmission, distribution and equipment operation in the power industry, to healthcare and scientific research. High voltage is often necessary to reduce energy losses due to resistance in the transmission lines.
Low voltage, on the other hand, is generally used for residential and industrial applications, as well as for communications and data transmission. Low voltage carries less energy and is not suitable for long distance transmission. Low voltage power systems are typically rated at below 1000 volts (V).
High voltage power systems are typically rated at above 1000V, and can go up to hundreds of kilovolts. High voltage systems require specialized equipment and trained personnel to handle them safely, whereas low voltage systems are much easier to manage and operate.
Although high voltage is defined by the DOE Electrical Safety Guidelines as any voltage over 600 volts, when it comes to LED lighting fixtures, any voltage of 208V and greater is considered a high voltage lighting fixture.
