Product Overview

The Philips 30652-2 C400S51/C is a 400W Ceramalux Comfort HPS lamp engineered for high-output outdoor and industrial lighting. It delivers 37,500 initial lumens (33,750 mean lumens at 40% of rated life), suited for applications where improved color rendition over standard HPS is desired, on standard HPS ballasts. The 2200K warm white 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 400W HPS lamp with ANSI code S51. Universal burn position allows installation in any orientation. Rated average life is 15,000 hours. This lamp contains mercury and must be recycled per applicable regulations.

Compatible Applications

Improved-color outdoor and area lighting — Where better color rendition than standard HPS is desired.
Retrofit onto standard HPS ballasts — No special ballast required.
Retrofit and maintenance replacement — Direct replacement for existing 400W HPS lamps with E39 Mogul Screw base and S51 ANSI code. Verify ballast compatibility before ordering.

Before Ordering — Verify

ANSI / Lamp Code: Confirm the existing lamp or equipment manual matches S51.
Wattage: Confirm the fixture is rated for 400W.
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.
