How You Can Save by Switching to LED Corn Bulbs

Image
Typically, when you see “switch and save,” the object of what you can save is money. If you switch from HID lamps to compatible LED corn bulbs, you can save money - and then some. But we need to walk before we can run. Let’s take a step back and look at the facts. First, what is an LED corn bulb ? What Is an LED Corn Bulb ? An LED is a light-emitting diode, a type of semiconductor material that emits light when electrical energy flows across the p-n junction of its surface. As electrical energy flows across it, some of that energy is released as visible light. Many industrial facilities use certain types of lightbulbs known as HID lamps, or high-intensity discharge lamps, for wide-area illumination. Some of the most common types of HID lamps are low and high-pressure sodium bulbs (LPS and HPS, respectively) mercury vapor lamps (MV lamps), and metal halide lamps, also known as MH lamps. HID lamps are very bright and have relatively long lifespans, and so they are commonly used to i...

Electrical Enclosure Standards: NEMA and IP Ratings

Image
Electrical enclosures are rigid, protective structures that are installed in electrical circuits and contain switches, buttons, connections, knobs, or displays. These structures provide a layer of protection to the circuit as well as to the electrical components contained within them; they also allow operators to interact with the system via switches, buttons, or other controls while protecting them against the risk of electrical shock. Electrical enclosures are rated according to their ability to encourage the release of excessive heat, to insulate the circuit and its components from electromagnetic interference, or simply to protect against the elements. Just what electrical enclosure is most suitable for a given circumstance, however, is subject to its categorization according to certain systems, of which the two most widespread are the IP and NEMA standards.
