The Genie 160077GT is a genuine OEM Lamp MH 1000W BT37HOR designed for Genie and Terex portable and towable light towers, including the AL4000, AL4, AL5HT, AL5 with Vertical Mast, TML-4000, TML-4000N, RL4, RL4 Vertical Mast, and RL4000. As a direct OEM replacement, this lamp is built to the same specification as the original, ensuring consistent light output and a correct fit in the factory lamp housing. Cross-reference part number 160077GT against your machine's parts manual to confirm it is the right lamp for your specific unit before ordering.
Key Features
- Genuine OEM Lamp Grade — Sourced directly from Genie, this 1000W metal halide lamp meets the original output and burn-position specifications required by the light tower's fixture design.
- BT37HOR Envelope, Exact Fit — The BT37 bulb envelope and horizontal burn orientation match the original lamp socket and reflector geometry, so this lamp seats and aligns correctly without modification.
- Broad Light Tower Compatibility — Fits a wide range of Genie and Terex light tower families, including AL, RL, and TML series models, covering both portable and towable configurations.
- Consistent Light Output — A correct-specification lamp sustains the rated 1000W arc and color temperature the fixture was designed around, delivering uniform site illumination across the full beam pattern.
- Electrical Safety — Using the correct OEM lamp type protects the ballast from mismatched electrical load; an incorrect lamp wattage or burn position can damage the ballast and create a fire or shock risk on a jobsite.
A metal halide lamp produces light by passing an electrical arc through a mixture of mercury vapor and metal halide salts sealed inside the arc tube. In a light tower application, the lamp is the primary light source — when it fails, darkens, or shifts color, site illumination drops immediately. The BT37HOR designation identifies the bulb's envelope shape and required burn orientation; installing a lamp with the wrong orientation or envelope in the same socket can cause premature failure or ballast damage. Replacing a spent lamp with the correct Genie 160077GT lamp restores full output and keeps the light tower operating safely through its intended duty cycle.
