Product Overview

The Philips 32386-5 C1000S52/ED37 is a professional-grade HPS replacement lamp engineered for the highest-output commercial and industrial lighting applications. At 1000 watts, it delivers 125,000 initial lumens (~112,000 mean lumens) — making it well suited for sports facilities, large industrial high-bay fixtures, outdoor stadiums, and high-mast area lighting where maximum light output over a large area is required. The warm amber 2100K output is characteristic of High Pressure Sodium technology.

The ED37 small outer envelope and E39 Mogul Screw base make this a direct replacement in fixtures previously housing a standard 1000W HPS lamp with ANSI code S52. The nominal operating voltage is 225V — confirm your ballast is rated for this voltage before ordering. Universal burn position allows installation in any orientation. Physical dimensions are 11.5" maximum overall length x 4.625" diameter — verify fixture clearance before ordering.

Not recommended for: retail displays, color-critical inspection environments, or any application requiring CRI above 21.

Compatible Applications

Sports and recreational facilities — Stadiums, arenas, racetracks, and large outdoor sports lighting installations.
Industrial high-bay and high-mast — Warehouses, manufacturing facilities, shipyards, and high-mast area lighting.
Outdoor area and roadway lighting — Large parking facilities, highways, and perimeter security lighting.
Retrofit and maintenance replacement — Direct replacement for existing 1000W HPS lamps with E39 base and S52 ANSI code. Verify ballast compatibility and voltage before ordering.

Before Ordering — Verify

ANSI / Lamp Code: Confirm the existing lamp or equipment manual matches S52.
Wattage: Confirm the fixture is rated for 1000W.
Operating Voltage: Confirm the ballast and equipment support 225V lamp operation.
Base Type: Confirm the socket matches E39 Mogul Screw.
Ballast Compatibility: This lamp requires an HPS-rated ballast and ignitor. It will not operate on a Metal Halide or Mercury Vapor ballast.
Burn Position: Fixture supports Universal operation — no restriction.
Physical Fit: Confirm ED37 bulb shape, 11.5" MOL, 4.625" diameter, and fixture clearance against the existing lamp or fixture manual.

Safety and Handling Guidelines

Correct Ballast Required: Use only with an HPS-compatible ballast and ignitor rated for this lamp. Using an incompatible ballast can result in lamp failure or fixture damage.
High-Pressure Arc Tube: HPS lamps operate under high internal pressure. Always use appropriate eye protection when handling or replacing lamps. Allow lamps to cool fully before removal.
Warm-Up / Restrike Time: HID lamps require a warm-up period to reach full output. After a power interruption, allow the lamp to cool before restarting — a hot restrike attempt can damage the lamp or ballast.
Approved Fixtures Only: Install only in fixtures rated for the listed lamp type, wattage, voltage, and operating position.
Mercury Content: Contains mercury. Do not dispose of in regular trash. Recycle through an approved lamp recycling program in accordance with federal, state, and local regulations.

Compliance

Contains mercury — subject to applicable lamp recycling and disposal regulations. California, Washington, and other states may have mandatory take-back or handling fee requirements.
Verify RoHS compliance status, UL listing, Title 20, and Prop 65 requirements with the Philips manufacturer specification sheet prior to use in regulated installations.
