Warranty periods for high-mast lighting systems vary depending on the specific components and the supplier. Generally:
Poles and Headframes: Manufacturers typically offer a 5–10 year structural warranty (excluding surface coatings). Top-tier manufacturers guarantee no structural failure for 10 years.
Luminaires (LED components): The warranty for LED chips is usually 3–5 years (based on L70 lumen maintenance standards), while LED drivers are covered for 2–3 years. Some premium brands (e.g., Philips, Eaton) offer a 5-year warranty on the complete luminaire unit.
Lifting System: Mechanical components such as winches, steel cables, and pulleys are typically covered for 1–2 years (excluding wear-and-tear parts).
Electrical Components (circuit breakers, contactors, SPDs, etc.):** Usually covered for 1–2 years, in accordance with the original manufacturer's warranty. In general contracts, the overall system warranty is commonly 2–3 years (starting from the date of acceptance). Warranty periods can be extended (e.g., to 5 years) during negotiations, though this will result in a higher price.
It is advisable to clarify the scope of the warranty during procurement: Does it cover labor costs? Does it include costs for high-altitude operations? Is lumen depreciation measured against the L70 standard? Is third-party insurance included? Ensure the original warranty certificate is retained. For critical projects, purchasing an extended warranty service is an option.
