High Pressure Sodium Lamps: A Complete Guide for Buyers in 2025
High Pressure Sodium (HPS) lamps have been a popular choice for industrial, commercial, and outdoor lighting for decades. Known for their efficiency and long lifespan, these lamps continue to be relevant in 2025 despite the rise of LED alternatives. This guide will help you understand the different types of High Pressure Sodium Lamps, their applications, and how to source them reliably from China.
How to Find Reliable High Pressure Sodium Lamps from China in 2025
Sourcing High Pressure Sodium Lamps from China requires careful consideration. Look for manufacturers with ISO 9001 certification and a proven track record in lighting production. Platforms like Alibaba.com list numerous suppliers, but always verify their:
- Minimum Order Quantities (MOQs)
- Production capacity
- Quality control processes
- Export experience
Request samples before placing bulk orders and check for proper packaging that protects the fragile arc tubes during shipping.
What Buyers Should Know Before Buying High Pressure Sodium Lamps from China
When importing High Pressure Sodium Lamps, consider:
- Voltage compatibility (110V/120V/220V/240V)
- Lamp base types (E26/E39/E40)
- Wattage options (35W to 1000W)
- Color temperature (typically 2000K-2200K)
Factor in lead times (typically 15-30 days) and shipping costs, which have increased since 2023. Some Chinese suppliers now offer DDP (Delivered Duty Paid) terms to simplify import processes.
Types of High Pressure Sodium Lamps
There are three main varieties:
- Standard HPS Lamps: Most common for street lighting and warehouses
- Deluxe HPS Lamps: Improved color rendering for retail spaces
- Convertible HPS Lamps: Can operate in both horizontal and vertical positions
Newer models in 2025 feature improved warm-up times (under 3 minutes) and better resistance to voltage fluctuations.
Functions and features of High Pressure Sodium Lamps
Key characteristics include:
- Luminous efficacy of 80-140 lumens per watt
- Average lifespan of 24,000 hours
- High intensity discharge (HID) technology
- Sodium vapor and mercury mixture in arc tube
Modern versions incorporate ceramic arc tubes instead of alumina for better performance. Some models now include smart dimming capabilities compatible with lighting control systems.
Scenarios of High Pressure Sodium Lamps
Despite LED competition, HPS lamps remain ideal for:
- Street and highway lighting (especially in foggy areas)
- Warehouse and industrial lighting
- Greenhouse cultivation (promotes plant growth)
- Parking lot and security lighting
A 2024 study showed HPS lamps still dominate 38% of municipal street lighting in North America due to their reliability in extreme temperatures.
How to Choose High Pressure Sodium Lamps
Selection factors:
- Application: Higher wattages (400W+) for large areas
- Fixture compatibility: Check ballast requirements
- Operating position: Some models are position-sensitive
- Color requirements: Deluxe versions for better CRI
For Chinese suppliers, prioritize those offering ROHS compliance and LM-79 test reports. Consider lamps with built-in igniters for easier installation.
High Pressure Sodium Lamps Q & A
Q: How long do High Pressure Sodium Lamps last?
A: Typically 24,000 hours, but proper maintenance can extend this to 30,000 hours.
Q: Are HPS lamps being phased out?
A: While declining in some markets, they remain popular for specific applications where their spectrum and efficiency are advantageous.
Q: Can I use HPS lamps with LED fixtures?
A: No, they require specific HID fixtures with compatible ballasts.
Q: Why choose HPS over LED?
A: Lower upfront cost, better performance in cold weather, and proven reliability in industrial settings.
Q: How do I dispose of burnt-out HPS lamps?
A: They contain mercury and require special recycling - check local regulations.
