The high bay is a fixture in the lighting world that you’d find in a warehouse, a factory, a gymnasium, or any vast open space with relatively high ceilings. Most current high bay lighting applications and low bay lighting use high-intensity discharge (HID) lamps such as metal halides or high-pressure sodium lamps.
Despite their widespread use, HID lamps are using antiquated technology, which directly and indirectly costs building managers. In particular, the use of HID lamps would result in: higher energy costs than the need, regular maintenance costs and poor lighting efficiency. Converting the current lighting to LEDs will solve both of these issues.
Energy conservation is a primary factor behind why LED lighting should be evaluated for your building or facility. Popular wattages for high bay LED fixtures can vary between 95 watts and 495 watts. The same range is 175 watts to 1000 watts if we equate this wattage to a standard HID high bay unit. Therefore, you instantly reduce your energy consumption by 40% -60% by switching to LED lighting. Just put that in dollars, if you made a move to LED light, you would be saving $300 per fixture per year in energy costs. It can also impact the financial balance sheet depending on the size of the facility.
Reducing maintenance costs
You will also see a dramatic reduction in the upkeep of your high bay light fixtures by switching to LEDs. This is due to how LEDs produce light and how they move through their functional existence. Rather than ceasing to work correctly once a supply of fuel is drastically reduced, the LED’s light output degrades very slowly over time. As a result, an LED product’s operating life can be considerably longer than an HID Lamp, thereby dramatically reducing the required maintenance load. By converting traditional 400w HID high-bay lighting to LED, a typical building with industrial light fixtures will save up to $5,341 in maintenance costs alone over three years.
Lighting efficiency is a critical factor in determining the transition to a specific lighting style. LEDs are a head-and-shoulders above their HID counterparts from a performance perspective. LEDs use a multi-point design, which means they uniformly spread light on the desired surface. So, light rates over a given surface differ less between mounting locations of the fixture. Besides the even distribution of light, LEDs are available in various CCTs (correlated colour temperatures) and thus have several options for enhancing the visual perception of “brightness.” HID fixtures, by comparison, create a “bright spot” immediately below the bulb, with light rates dramatically reducing as the distance between fixtures increases.
Also, we can see that the implementation of an LED retrofit in your facility has three key drivers to consider. In converting, you would see immediate energy savings, reduced lighting maintenance frequency, and overall lighting efficiency.
