Osram LU150/55/ECO 150W High Pressure Sodium Hid Lamp

Product Description

The OSRAM LU150/55/ECO is a 150-watt high pressure sodium (HPS) HID lamp designed for commercial and industrial lighting installations. It delivers an initial output of 16,000 lumens with a mean output of 12,230 lumens over a rated life of 30,000 hours. The lamp operates on an S55/O ANSI-coded ballast at 55 volts and features an E39 mogul base for compatibility with standard HPS fixtures. With an E23.5 bulb shape and clear color, it is a lead-free design positioned as a direct replacement for standard HPS lamps that do not pass the Federal TCLP test, which can simplify end-of-life disposal compliance for facility managers and contractors.

This lamp is suited for a wide range of commercial, industrial, and outdoor applications including high bay and low bay warehouse lighting, architectural and canopy installations, floodlighting, and roadway fixtures such as cobra head and wall-mount configurations. It operates in a universal burn position, making it flexible across fixture orientations. With a warm-up time of 3 to 4 minutes and a hot restrike time of 1 minute, it performs consistently in demanding environments. Electrical contractors and lighting maintenance professionals handling exterior site lighting, parking structures, or industrial facilities are the primary installers of this lamp type.

Key Features

• 150-watt HPS output with 16,000 initial lumens and 30,000-hour rated life
• Lead-free construction — qualifies as a direct replacement for standard HPS lamps that fail the Federal TCLP test
• S55/O ANSI ballast code ensures correct ballast matching for existing HPS systems
• Universal operating position supports varied fixture orientations without re-lamping restrictions
• E39 mogul base fits standard commercial and industrial HPS luminaires
• Hot restrike time of 1 minute reduces downtime in cycled or fault-protected circuits

Compatibility

Designed as a direct OEM-style replacement for 150-watt high pressure sodium lamps operating on S55/O ANSI-coded ballasts with E39 mogul base sockets. Suitable for architectural, canopy, floodlight, high bay, low bay, industrial, and roadway cobra head and wall-mount fixture types.

Installation Notes

Installation should be performed by a qualified electrician. Always de-energize the fixture and allow the existing lamp to cool fully before handling, as HPS lamps operate at high internal temperatures and pressure. Verify ballast ANSI code matches S55/O before installation to avoid premature lamp failure or ballast damage. Refer to applicable NEC requirements for exterior and high-voltage luminaire work.
