Common Issues With Conventional High Bay Lighting
What are some common issues with conventional high bay lighting and low bay lighting fixtures and lamps?
All HID lamps have some inherent characteristics that can lead to issues for those managing the industrial lighting fixtures, commercial lighting fixtures, warehouse lighting fixtures, retail lighting fixtures, and gym lighting fixtures.
Common HID lamp wattages used for high bay lights and low bay lights range from 175 watts to 1000 watts. The higher the wattage the higher the light output. The function of the area being illuminated, combined with the quantity, spacing, and height of the ceiling and fixture mounting plays a role in the existing wattages that are utilized. A 400w or 1000w HID fixture (very common wattages for high bay lighting and low bay lighting fixtures) can cost up to $209 in addition to $525 to operate per lamp, per year, in electricity alone.
Maintenance costs are often a big concern for those managing industrial lighting fixtures, commercial lighting fixtures, warehouse lighting fixtures, and gym lighting fixtures. In addition to the potential lamp lifetime concerns, high bay lighting, being commonly mounted on ceilings in excess of 15 feet, often requires the use of a lift to change out a lamp or a ballast. Many buildings and facilities do not own a lift and thus have to hire an outside contractor to maintain these types of fixtures. These are expenses that can add up over the course of a few years. It can easily cost up to $1,200 in labor and material to maintain a single high bay light fixture over the course of three years.
The characteristics of your high bay lighting and low bay lighting can vary significantly. For example, if you are using metal halide lamps you may see light that is “whiter," but these types of lamps tend to have accelerated lumen degradation, meaning the light output of the lamps decrease quickly after initial install, and as a result the overall lifetime of the lamp decreases (we have all seen those high bay light fixtures that have “pink” lamps that are barely providing any lighting on the ground). If you are using high pressure sodium you may see longer “useful” life as these lamps see less lumen degradation than metal halide, but their fuel structure produces a very “orange” light with a very low CRI (color rendering index). So basically you trade a longer life for a poorer quality light, in regards to visual perspective.
