Wattage Options and Application Matching

The wattage of an HPS lamp directly determines its light output and suitable application. Common options include 70W (small areas, parking lots), 100W (medium commercial spaces), 150W (warehouses, large parking areas), 250W (industrial facilities, street lighting) and 400W (high-bay industrial, stadiums, major roadways). Southeast Asian sellers on Alibaba.com should clearly specify which applications each wattage is designed for, as buyers often search by use case rather than technical specifications alone.

Lifespan and Total Cost of Ownership

The 24,000-hour rated lifespan is one of HPS lamps' strongest selling points. For a facility running lights 12 hours per day, this translates to approximately 5.5 years before replacement. However, buyers need to understand that lumen depreciation occurs over time - most HPS lamps maintain 90% of initial output through their rated life. When selling on Alibaba.com, manufacturers should provide lumen maintenance curves alongside the basic lifespan claim to build credibility with sophisticated buyers.

HPS lamps have a lifespan of approximately 24,000 hours and maintain 90% lumen maintenance, but they have the worst color rendering of all lamp types with a characteristic yellow glow ^[4].
