LED520BT56/750/277-480 93322990 — GE 520W High Output LED HID Lamp, BT56 EX39, 5000K, 106,000 Lumens

GE LED520BT56/750/277-480 93322990 — 520W High Output LED HID Replacement Lamp, BT56, 5000K, EX39 Mogul, Ballast Bypass Type B

The GE LED520BT56/750/277-480 (Order Code 93322990) is a 520-watt LED High Output HID replacement lamp from GE/Current Lighting Solutions, designed as a Type B ballast-bypass retrofit for 1000W HPS or 1500W metal halide fixtures. This BT56 corn-cob style lamp matches the ANSI length and diameter of the HID lamp it replaces, with omnidirectional light output for compatibility with existing fixture optics. With an EX39 mogul base, 5000K daylight color temperature, CRI greater than 70, 106,000 initial lumens, 204 LPW efficacy, and a rated life of 50,000 hours, this lamp delivers up to 16x longer life than HID while using significantly less energy. cULus certified, rated for Damp and Enclosed locations. The existing fixture must be rewired to bypass the ballast. Sold 3 per carton. Verify ballast bypass wiring and voltage range before ordering.

Technical Specifications

Product Overview

The GE LED520BT56/750/277-480 is part of Current's High Output BT56 lineup, a Type B ballast-bypass LED lamp engineered to directly replace a 1000W HPS or 1500W metal halide HID lamp, requiring the existing fixture to be rewired to bypass the ballast entirely. As the highest-output lamp in the BT56 family, it delivers industry-leading lumen output, making it possible to upgrade demanding high-wattage HID applications without replacing the entire fixture. This eliminates the ongoing cost and hassle of ballast replacement and maintenance, while lasting 3x to 16x longer than the HID lamps it replaces and significantly reducing energy consumption for comparable light output.

GE's proprietary active cooling design enables this lamp's compact, high-output construction, with omnidirectional light distribution similar to traditional HID lamps — this allows the LED replacement to work effectively with existing fixture reflector optics designed around an HID lamp's light pattern. The BT56 bulb shape and EX39 mogul base match the ANSI length and diameter of the 1500W metal halide lamp it replaces. A tether kit, horizontal support kit, and in-line misapplication fuse are all included standard, supporting safe installation in overhead and horizontally-mounted high-bay applications. Dimming is supported only through external Variac control devices — standard phase-cut (Triac) dimmers are explicitly not compatible and should not be used with this lamp.

Compatible Applications

• High-output HID retrofit projects — Direct ballast-bypass replacement for 1000W HPS or 1500W metal halide fixtures using existing fixture housings.
• Sports lighting and large area lighting — Stadiums, ball fields, and high-mast applications previously served by high-wattage metal halide.
• High-bay industrial and large canopy fixtures — Where ballast bypass wiring is permitted and fixture is rated for the application.
• Commercial and industrial facilities — Seeking substantial energy savings and reduced maintenance versus legacy high-wattage HID lighting.

Before Ordering — Verify

• Ballast Bypass Required: The existing fixture must be rewired to bypass the ballast entirely — this is a Type B lamp, not a plug-and-play ballast-compatible retrofit.
• Input Voltage: Confirm your circuit falls within 277–480V.
• Existing HID Wattage: Confirm you are replacing a 1000W HPS or 1500W metal halide lamp.
• Dimming: Do not use with phase-cut (Triac) dimmers. Dimming is supported only via external Variac control devices.
• Physical Fit: Confirm 12.8" MOL and 5.6" diameter fit within your fixture housing, with a minimum compartment volume of 1,813 in³ (approximately 11" x 11" x 15").
• Fixture Location: Rated for Damp and Enclosed locations only.
• DLC Status: Verify current DLC QPL qualification at designlights.org/search if required for a utility rebate program.
• Carton Quantity: Minimum order quantity is 3 units (1 carton).

Safety and Installation Guidelines

• Disconnect power before installing or servicing.
• Qualified Electrician Required: Ballast bypass wiring should be performed by a qualified electrician familiar with rewiring HID fixtures for Type B LED lamp operation.
• In-Line Fuse: Install the included in-line misapplication fuse kit per manufacturer instructions to protect against incorrect wiring.
• Tether and Horizontal Support Kits: Install the included tether kit and horizontal support kit, particularly important in overhead or horizontally-mounted applications.
• Dimmer Compatibility: Do not connect to phase-cut dimmers. Use only with external Variac control devices if dimming is required.
• Location Rating: Confirm fixture is rated Damp or Enclosed; not rated for hazardous or air-tight explosive locations.

Compliance

• cULus listed. DLC ID S-MMD144 — verify current qualification at qpl.designlights.org/solid-state-lighting.
• RoHS compliant — contains no lead or mercury. No mercury-related shipping restrictions apply.
• Rated for Damp, Enclosed locations per manufacturer High Output BT56 specification sheet (LEDL183).
• Covered by U.S. Patents 10788163 and 10508776 (and potentially other pending applications).
• 5-year limited warranty.
