Product Overview

GE LED450BT56/740/208/277 93153122 — 450W LED HID Replacement Lamp, BT56, 4000K, EX39 Mogul, Ballast Bypass Type B

The GE LED450BT56/740/208/277 (Order Code 93153122) is a 450-watt LED HID replacement lamp from GE/Current Lighting Solutions, designed as a Type B ballast-bypass retrofit for 750W HPS or 1000W metal halide fixtures. This BT56 corn-cob style lamp matches the ANSI length and diameter of the HID lamp it replaces. With an EX39 mogul base, 4000K neutral white color temperature, CRI greater than 70, 65,000 initial lumens, 144 LPW efficacy, and a rated life of 50,000 hours, this lamp delivers 3.3x longer life than metal halide while using 60–75% less energy. cULus certified, Damp location rated. The existing fixture must be rewired to bypass the ballast. Sold 3 per carton. Verify ballast bypass wiring and voltage range before ordering.

Product Overview

The GE LED450BT56/740/208/277 is a Type B ballast-bypass LED lamp engineered to directly replace a 750W HPS or 1000W metal halide HID lamp, requiring the existing fixture to be rewired to bypass the ballast entirely. This eliminates the ongoing cost and hassle of ballast replacement and maintenance, while delivering 3.3 times longer service life than metal halide and using 60–75% less energy for similar light output. The BT56 bulb shape and EX39 mogul base match the ANSI length and diameter of the traditional 1000W HID lamp it replaces.

GE's proprietary active cooling design enables this lamp's compact, high-output construction, with omnidirectional light distribution similar to traditional HID lamps. An in-line misapplication fuse kit is included, and a tether kit and horizontal support kit are included with this BT56 shape. Dimming is supported only through external Variac control devices — standard phase-cut (Triac) dimmers are explicitly not compatible.

Compatible Applications

HID retrofit projects — Direct ballast-bypass replacement for 750W HPS or 1000W metal halide fixtures.
High-bay, area, site, and large canopy fixtures — Where ballast bypass wiring is permitted.
Commercial and industrial facilities — Seeking energy savings versus legacy high-wattage HID lighting.

Before Ordering — Verify

Ballast Bypass Required: The fixture must be rewired to bypass the ballast.
Input Voltage: Confirm your circuit falls within 208–277V.
Existing HID Wattage: Confirm you are replacing a 750W HPS or 1000W metal halide lamp.
Dimming: Do not use with phase-cut dimmers; external Variac control only.
Physical Fit: Confirm 12.3" MOL and 5.6" diameter fit, with minimum compartment volume of 1,813 in³.
Fixture Type: Open or Enclosed only; not for hazardous locations.
DLC Status: Verify current qualification at designlights.org/search.
Carton Quantity: Minimum order quantity is 3 units (1 carton).
