Halco ProLume 208132 (LU400/ECO) HPS Lamp — 400W | ANSI S51 HID Arc Tube | 48,000 Lumens | E39 Mogul Screw Base

The Halco ProLume® 208132 (LU400/ECO) Lamp is an industrial-grade, high-intensity discharge (HID) high pressure sodium capsule engineered exclusively for public roadway fixtures, multi-level commercial parking structures, outdoor area security floods, municipal building washes, and high-bay warehouse distribution centers. Delivering an intensive 48,000 initial lumens of high-visibility 2000K warm amber illumination, this premium clear lamp features an authoritative ANSI S51 specification tracking profile and utilizes a recessed polycrystalline alumina (PCA) arc tube design to reduce potential electrical failure points. Outfitted with a heavy-duty brass E39 Mogul Screw base and a robust ED18 hard glass envelope, it ensures superior lumen maintenance up to 80% across its extended 24,000-hour rated average service life.

ADL Supply Expert Application & Replacement Guide

The Halco ProLume® 208132 industrial gas-discharge capsule is an established electrical field contractor baseline specified universally across municipality street grids, heavy production bays, commercial parking perimeters, and industrial warehouse interiors. Operating inside a high-purity clear hard glass enclosure, this unballasted lamp requires a matched external magnetic or electronic core-and-coil ballast loop to deliver structural striking voltages and safely control operational line parameters. The specialized recessed ceramic arc tube format controls sodium migration over extended periods, enabling regional facility maintenance teams to maintain high-efficiency center-beam lumen transmission while lowering routine spot replacement intervals.

Critical Ballast Coordination and High-Heat Mogul Socket Seating Parameters: Commercial facility managers and electrical crews executing large-scale retrofits must analyze line circuit properties closely prior to checkout: this high pressure sodium element tracks a strict ANSI S51 ballast tracking registry. Forcing or striking this 400W component down lines driven by legacy mercury vapor or standard metal halide components will trigger immediate color cycling instability, damage internal transformer blocks, or lead to an early arc tube shutdown.

Furthermore, turn the oversized E39 Mogul screw base firmly into the porcelain socket receiver track until the bottom center contact locks completely flush. Because driving a continuous 400W discharge payload inside a compact ED18 housing pushes outer envelope thresholds to intense operating temperatures, any thread cross-seating, surface carbon pitting, or socket degradation will generate high contact resistance. This resistance prompts rapid localized thermal expansion that can shatter the metal pinch-seal or fuse the lamp base permanently into the host luminaire socket assembly.

Operation, Safety & Mounting Compliance

High-Pressure HID Strike, Ignition & Restrike Cooling Loops

This High Pressure Sodium lamp operates via an internal metallic vapor arc discharge matrix that requires an external high-voltage starting strike pulse from a matched ballast network. Following initial arc striking, the capsule undergoes a standard 3 to 5-minute warm-up session as the sodium amalgam vaporizes to full luminosity output.

In the event of a sudden utility line power drop or localized interruption, the lamp cannot strike instantly while hot; it requires a built-in restrike cooling delay window lasting 3 to 5 minutes. This cooling period allows internal chamber pressures to drop back down to safe baseline strike parameters, protecting your facility circuits and fixture internal components from extreme over-amperage stress.
