GE 93154647 LED150ED28/740/277/480/HAZ

GE Current 93154647 LED150ED28/740/277/480/HAZ - 150W LED HID Hazardous Location Lamp 4000K 23,500 lm EX39 277-480V DLC Qualified

The GE Current 93154647 (LED150ED28/740/277/480/HAZ) is a Type B LED HID retrofit lamp explicitly UL-certified for installation in hazardous (classified) locations. Delivering a massive 23,500 lumens at a crisp 4000K neutral white, this 150W high-efficiency lamp directly replaces traditional 310W High-Pressure Sodium (HPS) or 400W Metal Halide (MH) HID lamps on high-voltage electrical circuits. It operates via internal driver ballast bypass directly on 277-480V line power, instantly eliminating ballast maintenance costs while slashing energy consumption by over 50%. Engineered with an EX39 mogul base and an ED28 jacket, its robust design is optimized for heavy industrial, petrochemical, and grain handling facilities running high-voltage distribution networks where rugged reliability is paramount. With a 50,000-hour L70 rated life, it outlasts traditional HID sources by up to 2.5 times.

Hazardous Location Certifications

UL-certified as part of a Retrofit Luminaire Conversion Kit for safe use in the following classified commercial environments under the National Electrical Code (NEC):

• Class I, Division 2, Groups A, B, C, D — Areas where flammable gases, vapors, or liquids are handled but not normally present in ignitable concentrations (e.g., Acetylene, Hydrogen, Ethylene, Hexane, Gasoline).
• Class II, Division 1, Groups E, F, G — Locations where combustible dusts are normally present in suspension under routine operating conditions (e.g., Metal dusts like aluminum/magnesium, carbonaceous dusts like coal/coke, and agricultural dusts like grain/flour).
• Class II, Division 2, Groups F, G — Environments where combustible dusts are not normally in suspension but can accumulate (carbonaceous and miscellaneous dusts).
• Temperature Code: T4 — Evaluated to maintain a safe maximum external surface temperature profile of 135°C or lower when operated within its safe operating temperature range.

Technical Specifications

Product Overview

The GE Current 93154647 hazardous location retrofit lamp offers a professional grade solution to bring legacy explosion-proof and classified area fixtures into the LED era. Delivering 23,500 lumens at a highly efficient 157 lumens-per-watt, this lamp ensures crisp, high-visibility lighting without sacrificing safety margin. The 4000K neutral white color temperature offers an excellent balance of clear, crisp white light that improves visual clarity in heavy manufacturing and processing plants. Because it relies on a Type B ballast bypass design engineered for 277-480V systems, installers cut the existing HID ballast out of the circuit completely, eliminating the primary point of failure and parasitic ballast energy draws forever. Outfitted with an integrated 6kV surge suppressor, it is purpose-built to survive line fluctuations common in heavy manufacturing environments.

Approved UL‑Certified Fixtures for ED28

The following fixture families are approved for use with this ED28 lamp. Note: approval depends on the classification; refer to the GE installation guide for the complete matrix and relabeling instructions.

Class I, Division 2 – Gases & Vapors

• GE Lighting Filtr‑Gard® H2 Series
• Appleton Mercmaster™ II
• Appleton Mercmaster™ III
• Crouse‑Hinds Champ® VMV
• Thomas & Betts Hazlux® 3 Series
• Hubbell Killark® VM Series
• Holophane Petrolux® II PETL

Class II, Division 1 (Groups E,F,G) & Division 2 (Groups F,G) – Combustible Dusts

• Appleton Mercmaster™ II
• Appleton Mercmaster™ III
• Crouse‑Hinds Champ® VMV
• Thomas & Betts Hazlux® 3 Series
• Hubbell Killark® VM Series
• Holophane Petrolux® II PETL

Important Fixture Compliance Note: For the ED28 form factor, the GE Filtr-Gard H2 is gas-only (not approved for dust environments). Additionally, the GE Powr-Gard H9 and the Holophane Petrolux P3M housing lines are not approved for deployment with this larger ED28 model profile. Always verify physical clearance and classification mappings via the official factory conversion documentation before scheduling installation threads.

Typical Applications

• Oil refineries, offshore drilling operations, fuel storage nodes, and petrochemical complexes running high-voltage lines.
• Grain storage towers, industrial flour mills, bakeries, and agricultural feed processing sites.
• Pulp and paper mills, textile mills, and wood machining operations where combustible airborne particles exist.
• Wastewater treatment hubs, chemical synthesizers, and heavy engineering shops.
• Indoor high-bay storage areas or outdoor perimeter layouts running 277V or 480V line power seeking robust utility rebate validation via DLC listing status.

Before Ordering – Verify

• Voltage Compatibility: This lamp operates safely across standard high-voltage 277V up to 480V building distribution systems. It is not compatible with low-voltage 120V circuits. For 120-277V environments, please see sibling part number 93154635.
• Physical Fitment: Check fixture internals against the lamp dimensions (MOL: 8.3", Diameter: 4.1") to confirm physical clearance inside sealed explosion-proof globes.
• Socket Check: Ensure your application luminaire possesses an EX39 mogul-style socket.
• Ballast Bypass Requirement: This lamp cannot run off an existing HID ballast. The fixture must be re-wired by an electrician to bring direct line voltage straight to the socket prior to spinning the new bulb in.
• Dimming Circuit Warnings: Do not use this item on ordinary forward/reverse phase-cut TRIAC wall-dimmer switches; it is designed only to support dimming loops via external Variac variable-transformer gear.
• Field Relabeling Requirement: In strict compliance with UL hazardous classification codes, the installer must apply the warning conversion sticker provided in the box directly to the structural body of the fixture to denote that the electrical properties have changed.

Safety and Handling

This is heavy-duty industrial apparatus intended specifically for hazardous industrial areas. Retrofitting must be completed by a licensed industrial electrician in strict compliance with local codes and National Electrical Code Articles. Always cut the power feed at the main panel breaker and double-check line-dead status before attempting to touch structural wires or cleaning internal housings. Allow a sufficient cooling down phase before removing existing hardware to prevent burn injuries.

Compliance
