Reasons for Outdoor Lighting Maintenance

Unlike indoor lighting systems, which require minimal yearly maintenance, outdoor lighting systems necessitate at least annual scheduled upkeep due to their exposure to harsh environmental conditions. Some of the biggest factors contributing for the need to perform maintenance include:

Physical Damage:

Outdoor fixtures, situated within landscapes near sidewalks, paths, or amidst foliage, endure frequent abuse from various sources such as children or gardeners. Over time, this can result in misalignment or displacement of fixtures, thereby disrupting the intended lighting arrangement.

Water Deposits:

Many regions in the United States have water sources containing high levels of calcium, leading to the accumulation of calcium deposits on fixture lenses. This residue obstructs the light emitted from the fixture, significantly diminishing its illuminating capacity. Regular cleaning, typically incorporated into an annual maintenance plan, is essential to mitigate this issue.

Fertilizers and Mulch:

Regular applications of fertilizers and mulch in yards often result in these substances coming into contact with outdoor lighting fixtures. This can impede the light output and potentially cause damage to the fixture by trapping heat generated by the light source.

Plant Growth:

As plants in the landscape grow over time, adjustments to the positioning or relocation of lighting fixtures become necessary. Changes in plant size can alter the effectiveness of lighting angles, leading to undesirable "hot spots" or uneven illumination. Consequently, readjustments to lamp positioning, wattage, beam spreads, or optical lenses may be required to maintain optimal lighting effects.

General Maintenance:

Routine maintenance tasks, such as greasing o-rings to prevent drying out and applying anti-seize compounds to screws and threads, are crucial for ensuring the longevity and functionality of outdoor fixtures. Neglecting these simple yet essential steps can lead to premature failure of the fixtures.

In summary, regular maintenance of outdoor lighting systems is imperative due to the environmental challenges they face and the potential for physical damage, water deposits, interference from landscaping materials, and the impact of plant growth. By adhering to a comprehensive maintenance plan, homeowners can preserve the functionality and aesthetic appeal of their outdoor lighting installations.
