A Practical Evaluation of Replacing HID Lamps with Corn Cob LED Lights
About 20 years ago, the price of semiconductor materials that are used to make LEDs fell substantially, dropping the price of LEDs around the world. Since that time, LEDs, which previously were cost-prohibitive to manufacture, buy and implement, have been widely adopted around the world as replacement and retrofit lighting. They have been used to replace incandescent, halogen, fluorescent, and of course, high-intensity discharge lamps. By and large, the biggest benefit of LED lighting is in its energy efficiency. For many institutions, warehouses and manufacturing facilities, LEDs are the top choice simply because they are so much more energy efficient than alternatives. For instance, many industrial settings use HID, or high-intensity discharge lamps, such as mercury vapor, metal halide lamps, and high and low pressure sodium lamps. These lamps, while they offer excellent light output and color temperature, produce a lot of heat and are not energy efficient - nowhere near as ...
