The global market for High Pressure Sodium (HPS) lamp ignitors is in a state of structural decline, driven by the rapid adoption of more efficient LED technology. The market is projected to contract at a compound annual growth rate (CAGR) of -8.5% over the next five years, shrinking from an estimated $215M in 2024. The primary strategic challenge is not growth, but managing supply chain continuity for legacy systems while planning a cost-effective transition. The most significant threat is technology obsolescence, which will accelerate supplier consolidation and potentially limit future availability for maintenance, repair, and operations (MRO) needs.
The global Total Addressable Market (TAM) for HPS lamp ignitors is experiencing a significant contraction. The primary application—street lighting, industrial high-bay, and horticulture—is rapidly transitioning to LED solutions. While a residual MRO market will persist, new installations are minimal. The largest geographic markets remain regions with extensive, yet-to-be-upgraded public and industrial lighting infrastructure.
Key Markets (by est. demand): 1. Asia-Pacific (led by India and parts of Southeast Asia) 2. North America 3. Europe
| Year | Global TAM (est. USD) | CAGR (5-Yr Rolling) |
|---|---|---|
| 2024 | $215 Million | -8.5% |
| 2026 | $180 Million | -8.7% |
| 2028 | $150 Million | -9.0% |
The competitive environment is characterized by established lighting giants who historically dominated the HID market and are now managing the HPS portfolio as a legacy category. Barriers to entry are low from a technical standpoint but high in terms of achieving the scale, quality certifications (e.g., UL, CE), and distribution networks required to serve a global MRO market.
⮕ Tier 1 Leaders * Signify (formerly Philips Lighting): Dominant global player with a comprehensive portfolio and extensive distribution, offering OEM and aftermarket components. * Acuity Brands: Strong presence in North America, particularly in industrial and infrastructure lighting systems; offers integrated solutions. * Venture Lighting (Advanced Lighting Technologies): Specialist in HID technology, including HPS, with a strong reputation for quality components in a shrinking market. * Tridonic: European leader in lighting components, known for high-quality ballasts and ignitors, now heavily focused on LED drivers but maintaining legacy support.
⮕ Emerging/Niche Players * B.A.G. Electronics (Germany): Niche component specialist with a focus on quality and reliability for specific industrial applications. * Various unbranded/private-label manufacturers (Asia): Low-cost producers primarily serving regional aftermarket needs, often with variable quality. * ELT (Especialidades Luminotécnicas S.A.U.): Spanish manufacturer of ballasts and ignitors for a range of lamp technologies.
The price of an HPS ignitor is primarily a function of material costs, manufacturing overhead, and logistics. Given the commoditized nature and declining volume, manufacturer margins are thin. The typical price build-up consists of electronic components (~40%), copper windings for the pulse transformer (~20%), assembly labor (~15%), housing and potting (~10%), and SG&A/margin (~15%).
Pricing is typically set on a cost-plus basis, with volume discounts for major distributors or OEMs. As volumes decline, manufacturers may lose purchasing power for raw materials, putting upward pressure on unit costs despite falling demand. The most volatile cost elements are tied to global commodity and electronics markets.
Most Volatile Cost Elements (Last 12 Months): 1. Copper: +12% change, impacting the internal pulse transformer. [Source - LME, May 2024] 2. Semiconductors (Diodes, Thyristors): -5% change, as general-purpose component supply has stabilized post-pandemic. 3. Freight & Logistics: +8% change, driven by fuel costs and geopolitical disruptions in key shipping lanes.
Innovation in HPS technology is virtually non-existent; all R&D investment has shifted to LED. Recent market activity is centered on end-of-life management and portfolio adjustments.

Demand for HPS ignitors in North Carolina is driven by MRO needs from three core areas: legacy municipal street lighting, large-scale agricultural operations (horticultural lighting), and older manufacturing/warehouse facilities. While major cities like Charlotte and Raleigh are aggressively pursuing LED conversion projects, many smaller municipalities and rural areas still maintain significant HPS infrastructure. The state's strong industrial base means a persistent, albeit shrinking, MRO demand from high-bay lighting applications. Local supply is primarily handled through national distributors (e.g., Grainger, Graybar, Rexel) sourcing from the Tier 1 suppliers listed above. There is no significant local manufacturing capacity for this specific component; the state is a net importer. The outlook is for a 10-15% annual decline in demand within the state as public and private entities leverage federal and utility incentives for LED upgrades.
| Risk Category | Grade | Justification |
|---|---|---|
| Supply Risk | Medium | Market consolidation and SKU reduction could limit the availability of specific models. Key suppliers are stable but de-prioritizing the category. |
| Price Volatility | Medium | Declining volumes reduce supplier purchasing power on volatile raw materials (copper), potentially increasing unit costs despite falling demand. |
| ESG Scrutiny | Low | HPS lamps contain mercury, but the ignitor itself is a standard electronic component with low ESG focus compared to the lamp. |
| Geopolitical Risk | Low | Production is geographically diverse, and the technology is mature. Not dependent on highly contested or specialized supply chains. |
| Technology Obsolescence | High | The category is being actively replaced by a superior technology (LED). This is the primary strategic risk defining the market. |
Consolidate & Secure Last-Buy: Consolidate all MRO spend for HPS ignitors with a single Tier 1 supplier (e.g., Signify, Acuity) under a 1-2 year contract. Negotiate firm, fixed pricing in exchange for volume commitment and request a "last-time buy" schedule for critical SKUs. This will mitigate supply risk from SKU rationalization and secure predictable pricing on diminishing volumes.
Fund a Transition Pilot: Allocate $100k-$250k to partner with our Facilities team on an LED-retrofit pilot program for one to two sites still heavily reliant on HPS. Target a full payback within 24 months through energy savings (est. 60%) and maintenance avoidance. Use the performance data to build the business case for a multi-year, enterprise-wide transition away from the HPS category entirely.
