GE 14673 LU100/ECO/NC

Product Overview

GE 14673 LU100/ECO/NC — 100W High Pressure Sodium Lamp, E39 Mogul Base

The GE 14673 LU100/ECO/NC is a 100-watt High Pressure Sodium (HPS) Lucalox lamp from GE Lighting, designed for outdoor area lighting, street lighting, and industrial high-bay applications. With an E39 Mogul Screw base, ED23.5 bulb shape, ANSI code S54/O, and universal burn position, this lamp delivers 9,500 initial lumens and a 24,000-hour rated life. The NC (Non-Cycling) designation means this lamp is engineered to shut off rather than cycle on and off when it reaches end of life — protecting the ballast from the voltage stress caused by a cycling lamp. The ECO designation indicates RoHS compliance. Verify wattage, ANSI code, base type, and ballast compatibility before ordering — HPS lamps require an HPS-rated ballast and ignitor.

Product Overview

The GE 14673 LU100/ECO/NC is a professional-grade HPS replacement lamp engineered for outdoor and industrial lighting. At 100 watts, it delivers 9,500 initial lumens — reliable output for roadway, parking, and perimeter lighting applications where energy efficiency and long service life are the priority. The warm amber 2000K output is characteristic of High Pressure Sodium technology.

The NC (Non-Cycling) variant is an important distinction: standard HPS lamps near end of life can begin cycling — repeatedly striking, extinguishing, and restriking — which stresses the ballast and can shorten its service life. This Non-Cycling lamp is engineered to shut off cleanly at end of life rather than cycle, helping protect the ballast from that additional wear. This makes it a preferred choice for installations where ballast protection and reduced maintenance calls are a priority.

The ED23.5 bulb shape and E39 Mogul Screw base make this a direct replacement in fixtures previously housing a standard 100W HPS lamp with ANSI code S54/O. Universal burn position allows installation in any orientation. The ECO designation confirms RoHS compliance, though the lamp still contains mercury as required by HPS technology — see disposal guidelines below.

Not recommended for: retail displays, color-critical inspection environments, sports venues, or any application requiring CRI above 22.

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.
Ballast-sensitive installations — The Non-Cycling design makes this lamp well suited for applications where ballast protection and extended system life are priorities.
Retrofit and maintenance replacement — Direct replacement for existing 100W HPS lamps with E39 base and S54/O ANSI code. Verify ballast compatibility before ordering.

Before Ordering — Verify

ANSI / Lamp Code: Confirm the existing lamp or equipment manual matches S54/O.
Wattage: Confirm the fixture is rated for 100W.
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.
Variant: This is the Non-Cycling (NC) version — confirm your application calls for NC rather than standard cycling end-of-life behavior.
Burn Position: Fixture supports Universal operation — no restriction.
Physical Fit: Confirm ED23.5 bulb shape, length, 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, 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

ECO designation indicates RoHS compliance — reduced hazardous substances per GE Lucalox ECO series standards.
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 additional certifications (UL, Title 20, Prop 65) with GE manufacturer specification sheet prior to use in regulated installations.
