GE 93134833 LED21ED17/740/HAZ 21W 4000K LED Haz Lamp

GE 93134833 LED21ED17/740/HAZ - 21W LED HID Hazardous Location Lamp 4000K 3,000 lm E26/EX39 120-277V

The GE LED21ED17/740/HAZ is a Type B LED HID retrofit lamp UL-certified for installation in hazardous (classified) locations. At 21W and 3,000 lumens at 4000K neutral white, it directly replaces 50W high-pressure sodium or 70W metal halide HID lamps in petrochemical, food processing, grain handling, and heavy industrial environments. The E26 medium base ships with an EX39 mogul adapter included for use in either socket type, and the lamp includes 6kV surge protection. 50,000-hour L70 rated life delivers approximately 2.5x the service life of the HID lamps it replaces.

Hazardous Location Certifications

UL-certified as part of a Retrofit Luminaire Conversion Kit for the following hazardous (classified) locations under the National Electrical Code:

• Class I, Division 2, Groups A, B, C, D — flammable gases or vapors not normally present in ignitable concentrations (acetylene, hydrogen, ethylene, hexane, butane, propane, acetone, benzene, gasoline)
• Class II, Division 1, Groups E, F, G — combustible dusts normally present (metal, carbonaceous, agricultural)
• Class II, Division 2, Groups F, G — combustible carbonaceous and miscellaneous dusts not normally present
• Temperature Code: T4A (maximum surface temperature 120°C) at 65°C maximum ambient

Technical Specifications

Product Overview

This is the 4000K neutral-white variant of the entry-wattage GE Type B LED HID hazardous-location lamp family. At 21W delivering 3,000 lumens, it replaces standard 50W HPS or 70W metal halide ED17 lamps in classified industrial fixtures — cutting energy use by more than half while quadrupling lamp service life. The 4000K color rendering produces a balanced, neutral light well-suited to general work areas, processing floors, and tasks where natural color discrimination matters (vs. the warmer 3000K variant or cooler 5000K daylight option). Includes 6kV surge protection and ships with the EX39 mogul-base adapter.

Compatible UL-Certified Fixtures

This ED17 lamp is approved for use as a retrofit in the following UL-listed hazardous location fixtures (verify exact classification coverage per fixture family in the GE installation guide):

• For gas/vapor applications (Class I Div 2 ABCD): GE Lighting Filtr-Gard® H2 Series, Appleton Mercmaster™ II, Appleton Mercmaster™ III, Crouse-Hinds Champ® VMV, Thomas & Betts Hazlux® 3, Hubbell Killark® VM Series, Holophane Petrolux® P3M
• For combustible dust applications (Class II Div 1 EFG; Div 2 FG): GE Lighting Powr-Gard® H9 Series, Appleton Mercmaster™ II, Appleton Mercmaster™ III, Crouse-Hinds Champ® VMV, Thomas & Betts Hazlux® 3, Hubbell Killark® VM Series, Holophane Petrolux® P3M

Note: GE Filtr-Gard H2 is approved only for gas/vapor (Class I), while GE Powr-Gard H9 is approved only for dust (Class II). Other manufacturers' fixtures cover both classifications. Refer to the GE installation guide for the complete approved-fixture list and required fixture relabeling instructions.

Typical Applications

• Petrochemical plants, refineries, drilling rigs, and oil & gas production facilities
• Food and beverage processing facilities
• Grain elevators, flour mills, and agricultural processing operations
• Chemical manufacturing and storage
• Coal handling and carbonaceous-dust environments
• Industrial perimeter and security lighting in classified zones

Before Ordering – Verify

• Confirm the existing fixture is on the approved UL-certified list above. Use in non-listed fixtures voids hazardous location certification.
• Confirm the hazardous classification of the installation zone matches the lamp/fixture combination's certified rating
• Confirm the fixture's HID ballast has been physically bypassed or removed — this lamp will not operate on an existing HID ballast
• Confirm socket type (E26 medium or EX39 mogul); both are supported via the included adapter
• Confirm install ambient is between -20°C and 65°C
• Do not connect to phase-cut dimming circuits
• Per UL requirements, the fixture must be relabeled to indicate the new lamp and updated temperature code after retrofit
• If utility rebate eligibility is required, note that this E26-based SKU is not DLC-qualified; consult ADL Supply on rebate-eligible alternatives

Safety and Handling

Intended for installation in classified hazardous locations. Installation must be performed only by a qualified licensed electrician familiar with NEC Articles 500-506 governing hazardous (classified) location wiring methods. The retrofit luminaire conversion must follow the manufacturer's installation guide, including required fixture relabeling indicating the new lamp and temperature code. Always disconnect power at the breaker and confirm de-energized state before servicing fixtures. Allow lamp cool-down before handling.

Compliance

• Safety Certification: cULus
• Hazardous Rating: Class I Div 2 Groups A,B,C,D; Class II Div 1 Groups E,F,G; Class II Div 2 Groups F,G; T-Code T4A
• Location Rating: Damp (UL 1993)
• Wattage equivalency claims per NEMA LS 20037-2024 (formerly NEMA LL 10-2020)
• Covered under U.S. Patents 10,788,163 and 10,508,776
