Technical Specifications

Product Overview

The Philips 36877-9 C200S66/ALTO is a 200W Ceramalux HPS lamp engineered for high-output outdoor and industrial lighting. It delivers 21,400 initial lumens (19,260 mean lumens at 40% of rated life), suited for roadway, warehouse, and high-bay industrial lighting. The 2100K warm amber output is characteristic of High Pressure Sodium technology.

The ED-18 bulb shape and E39 Mogul Screw base make this a direct replacement in fixtures previously housing a standard 200W HPS lamp with ANSI code S66MN-200. Universal burn position allows installation in any orientation. Rated average life is 24,000+ hours. This lamp contains mercury and must be recycled per applicable regulations.

Compatible Applications

• Outdoor area and street lighting — Roadways, parking lots, municipal streetlights, and perimeter security lighting.
• Industrial and commercial high-bay — Warehouses, manufacturing facilities, and large indoor/outdoor commercial fixtures.
• Retrofit and maintenance replacement — Direct replacement for existing 200W HPS lamps with E39 Mogul Screw base and S66MN-200 ANSI code. Verify ballast compatibility before ordering.

Before Ordering — Verify

• ANSI / Lamp Code: Confirm the existing lamp or equipment manual matches S66MN-200.
• Wattage: Confirm the fixture is rated for 200W.
• 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 ED-18 bulb shape, LCL 5¾″, MOL 9¾″, and fixture clearance against the existing lamp or fixture manual.
• UPC/EAN: Not listed on the manufacturer datasheet used for this rebuild — confirm with Philips/Signify or your distributor before publishing barcode data.

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.
• Fixture Design: Do not use this lamp in a fixture that redirects a substantial portion of energy toward the arc tube and its immediate vicinity, as this may lead to early lamp failure.
• Approved Fixtures Only: Install only in fixtures rated for the listed lamp type, wattage, and operating position. The fixture wattage rating must match the wattage on the outer glass bulb.
• Handling: Do not scratch the outer bulb or subject it to pressure — this could cause the outer bulb to crack or shatter. Replace the lamp if the outer glass bulb has been scratched, cracked, or damaged in any way.
• If Broken: If the outer glass bulb is broken, shut off power immediately and remove the lamp after it has cooled. If the arc tube is broken, avoid skin contact with its contents or fragments.
• 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.
