The global market for Metal Halide (MH) lamps is in a state of terminal decline, with a current estimated size of $2.2B USD. The market is projected to contract significantly with a 3-year CAGR of -9.1% as end-users rapidly adopt superior LED technology. The single greatest threat is technology obsolescence, which is simultaneously our greatest opportunity: to accelerate a strategic transition to LED, capturing significant energy and maintenance savings. This brief outlines a strategy to manage the phase-out of MH lamps while mitigating supply risk.
The global Total Addressable Market (TAM) for MH lamps is contracting as LED retrofits and new builds become the default standard. The primary remaining demand is for Maintenance, Repair, and Operations (MRO) replacements in legacy infrastructure. The market is forecast to decline by over 40% in the next five years. The largest geographic markets are Asia-Pacific, driven by a vast installed base and slower replacement cycles in some developing nations, followed by Europe and North America.
| Year | Global TAM (est. USD) | 5-Yr CAGR (Projected) |
|---|---|---|
| 2024 | $2.2 Billion | -9.5% |
| 2026 | $1.8 Billion | -9.5% |
| 2028 | $1.5 Billion | -9.5% |
Barriers to entry are High due to the capital intensity of arc tube manufacturing, proprietary chemical formulations (metal halide salts), and the established, scaled distribution networks of incumbents.
⮕ Tier 1 Leaders * Signify (Philips): Global leader with the most extensive distribution network and a clear strategy to migrate customers from its legacy Philips-brand MH to its Interact LED systems. * ams OSRAM: Strong presence in automotive and specialty lighting (entertainment, horticulture); leveraging its Sylvania brand in the general lighting MRO market. * GE Lighting (a Savant company): Historic brand strength in North America, now focused on a managed decline of HID while promoting its LED and smart home product lines.
⮕ Emerging/Niche Players * Ushio Inc.: Japanese specialist with a strong focus on high-performance lamps for cinema, data projectors, and industrial applications. * Iwasaki Electric (EYE Lighting): Focuses on specialty HID lamps for horticulture, UV curing, and infrastructure, maintaining a foothold in niche applications. * Feit Electric: Primarily a retailer-focused brand that sources globally, offering replacement lamps for the residential and small commercial MRO market.
The price of an MH lamp is built up from raw materials, complex component manufacturing, and assembly. The arc tube, containing a precise mixture of argon, mercury, and metal halide salts, is the most critical and costly component. This is enclosed in a hard-glass outer bulb, often with a phosphor coating to improve color rendering.
The three most volatile cost elements are tied to specialized raw materials, where supply is concentrated and demand from other industries is high. 1. Rare Earth Metals (Scandium, Dysprosium): Used in the halide salt mixture. Price is highly sensitive to Chinese export policy and mining output. Recent Volatility: est. +20-30% over the last 18 months. 2. High-Purity Quartz: Required for the arc tube to withstand high temperatures and pressures. Supply is limited and in high demand from the semiconductor industry. Recent Volatility: est. +15%. 3. Tungsten: Used for the electrodes. Price is tied to global industrial and defense demand. Recent Volatility: est. +10%.

Demand for MH lamps in North Carolina is in steep decline and is now almost exclusively for MRO replacements. The state's large industrial base (manufacturing, food processing), university campuses, and municipal infrastructure represent the bulk of the remaining installed base. There is no significant MH lamp manufacturing capacity within North Carolina; supply is served entirely by the national distribution centers of firms like Graybar, WESCO, and Rexel. State-level energy efficiency programs and incentives, combined with corporate ESG goals, are actively encouraging the few remaining users to transition to LED.
| Risk Category | Grade | Justification |
|---|---|---|
| Supply Risk | High | Key suppliers are actively discontinuing product lines. Risk of specific model stock-outs is increasing, potentially disrupting MRO activities. |
| Price Volatility | Medium | Declining demand is offset by volatile raw material costs (rare earths, quartz) and reduced economies of scale from manufacturers. |
| ESG Scrutiny | Medium | Focus on mercury content (disposal liability under RCRA) and high energy consumption relative to LED alternatives. |
| Geopolitical Risk | Medium | High dependency on China for rare earth metals used in the halide salt mixture creates a potential supply chokepoint. |
| Technology Obsolescence | High | The technology is functionally obsolete. Remaining investment is a sunk cost with no future value. Continued use incurs a high opportunity cost. |
Execute a Managed Phase-Out. Immediately conduct a last-time-buy (LTB) analysis for any business-critical MH lamps that cannot be retrofitted in the next 12 months. Consolidate all remaining MRO spend with a single national distributor to secure inventory and leverage declining-volume spend for a 10% cost reduction. This mitigates the High supply risk for the short term.
Accelerate LED Transition. Mandate a full TCO analysis for all facilities still using MH lighting. Target a full LED conversion within 36 months, leveraging a 50-70% energy savings and typical payback periods of <3 years. Prioritize RFPs for LED fixture retrofits to capitalize on federal tax incentives (IRA) and utility rebates, eliminating obsolescence risk and advancing corporate ESG targets.
