Product information

Description

High-pressure sodium lamp Helios E40 100W is a single-ended sodium light source with an E40 screw base and a rated power of 100 watts. Designed for industrial and outdoor applications, this lamp produces warm amber light with high luminous efficacy, making it suitable where energy-efficient, high-lumen output is required. The lamp is intended for fixed luminaires with appropriate magnetic or electronic ballasts for high-pressure sodium technology and is commonly used in street lighting, warehouses, workshops and supplemental horticultural lighting.

Advantages

The Helios E40 100W sodium lamp offers a high lumen-per-watt ratio and long operating life typical for high-pressure sodium technology. Its E40 base ensures compatibility with standard industrial and street luminaires. The warm amber spectrum improves visual contrast in outdoor environments and contributes to reduced glare in large-area installations. The sealed single-ended design simplifies installation and replacement while maintaining stable light output when used with correct ballast and fixture.

Suitable for

Street and roadway lighting in municipal and industrial areas
Warehouse and factory lighting where high lumen output is needed
Workshops and outdoor service areas
Supplemental horticultural lighting for species responsive to orange-red spectrum
Parking lots and security lighting in combination with appropriate controls

How to use

Install the lamp into a compatible luminaire with an E40 socket and a ballast designed for high-pressure sodium lamps. Ensure power is disconnected before replacing the lamp. After installation, allow a short warm-up period for the lamp to reach full luminous output and stable color. Do not operate the lamp on mains without the correct ballast or on dimming circuits that are not specified for high-pressure sodium technology.

Usage recommendations

Operate the Helios E40 100W lamp in fixtures that provide adequate heat dissipation and protection from moisture to preserve service life. Use compatible ballasts and follow local electrical regulations. For horticultural applications, combine this lamp with full-spectrum fixtures if broader spectral coverage is required for vegetative growth stages.
