Product Overview

The GE 44047 LU250 is a 250W 2100K 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. This lamp must be operated on a compatible High Pressure Sodium ballast matched to ANSI code S50/O. HPS lamps are not interchangeable with metal halide 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 a High Pressure Sodium ballast rated for ANSI S50/O. Do not use on MH or mercury vapor ballasts.
Standby (SBY) hot-restrike: This lamp is designed to restart immediately after a power interruption via a standby circuit. Verify fixture compatibility before installation.
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.
