G E Lighting 26431 400W Hps ED18 Mogul Base Sodium Bulb

Product Description

The G E LIGHTING 26431 is a 400-watt Lucalox high pressure sodium (HPS) lamp built for demanding commercial and industrial lighting applications. Featuring an ED18 bulb shape with a mogul base, it delivers 51,000 lumens of output at a correlated color temperature of 2100 Kelvin. The clear outer envelope allows maximum light transmission, and the rated service life exceeds 24,000 hours, reducing relamping frequency in high-use installations. This lamp is a practical choice where long life and high lumen output matter more than color rendering. Licensed electricians and lighting maintenance technicians are the typical installers.

This lamp is suited for commercial and industrial environments such as warehouses, parking structures, manufacturing facilities, street lighting, and outdoor area lighting. The high pressure sodium technology provides strong lumen efficiency, making it effective for large spaces requiring broad illumination coverage. With a color rendering index (CRI) of 22, it is best applied in settings where task color discrimination is not a primary concern. The package quantity is four lamps per unit.

Installation Notes

High pressure sodium lamps must be installed by a qualified electrician in accordance with NEC requirements and the fixture manufacturer's specifications. Always de-energize the fixture and allow the existing lamp to cool completely before handling, as HPS lamps operate at high internal pressure and extreme temperatures. Use appropriate PPE including eye protection when handling lamps. Confirm ballast type and wattage rating match the lamp before energizing the circuit.
