The Genie 160077GT is a genuine OEM Lamp MH 1000W BT37HOR designed for Genie and Terex portable light towers, including the AL4000, TML-4000N, AL4, AL5HT, AL5 with Vertical Mast, RL4, and RL4 Vertical Mast. As a factory-original replacement, this lamp meets the same output and design criteria as the unit that came in your machine. Cross-reference part number 160077GT against your light tower's parts manual to confirm it is the correct lamp for your specific unit before ordering.
Key Features
- Genuine OEM Output Spec — Factory-original 1000W metal halide lamp manufactured to the exact output specification your Genie light tower was designed around, so light levels stay consistent with the original build.
- BT37HOR Bulb Type — The BT37 horizontal-burning envelope matches the fixture geometry and mounting orientation in AL and TML series light towers, ensuring the arc tube sits in the position the reflector was designed for.
- Direct OEM Replacement — Replaces the original lamp without modification to the fixture, wiring, or ballast assembly.
- Broad Light Tower Fitment — Fits multiple Genie and Terex portable light tower models, including the AL4000, AL4, AL5HT, AL5 with Vertical Mast, RL4, RL4 Vertical Mast, and TML-4000N.
- Sustained Illumination — A correct-spec lamp maintains the rated lumen output across the lamp's service life, keeping the work area lit to the level operators depend on during night or low-light operations.
A metal halide lamp is the primary light source in a jobsite light tower, converting electrical power into high-intensity white light through an arc discharge inside a pressurized arc tube. The BT37 bulb envelope is engineered for horizontal burning, meaning the lamp must be operated within the orientation the fixture requires — using the wrong burning position shortens lamp life significantly and can cause premature failure or arc tube fracture. When a lamp reaches end of life or fails early due to a damaged envelope or degraded arc tube, light output drops sharply or the lamp fails to strike altogether, leaving the work area dark. Replacing the lamp with the correct OEM part, such as the 160077GT, restores full illumination and protects the ballast from the strain of repeatedly attempting to strike a failing lamp.
