Product Overview

The GE 85371 LU150/55/H/ECO is a 150W 2000K Warm Amber GE Lucalox High Pressure Sodium lamp. Standby (SBY/XL) lamps feature hot-restrike capability — the lamp stays on a standby circuit after arc extinguishment, allowing immediate restart without the 10–20 minute cool-down required by standard HPS. Ideal for security, retail, and facilities requiring uninterrupted illumination.

HPS ballast required. Operate on a compatible HPS ballast matched to ANSI S55/O. Not interchangeable with MH or mercury vapor ballasts. Contains mercury — dispose per local regulations.

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 – Verify ANSI code and wattage before ordering. HPS lamps require an HPS-rated ballast.

Safety and Installation

HPS ballast required. Operate only on an HPS ballast rated for ANSI S55/O. Do not use on MH or mercury vapor ballasts.
Standby (SBY) hot-restrike: Designed to restart immediately after power interruption via standby circuit. Verify fixture compatibility.
Allow warm-up time: 3–5 minutes for full output.
Hot restrike: Immediate via standby circuit.
UV radiation: Use only in fixtures with UV-protective shielding. Do not operate with a broken or cracked outer envelope.
Mercury disposal: Contains mercury — dispose per local lamp recycling regulations.
