Product Overview
![]()
The GE Multi-Vapor® 18205 (MVR1000/U/BT37) Lamp is an industrial-grade, high-intensity discharge (HID) quartz metal halide bulb engineered for heavy-duty high-bay warehouse spaces, commercial manufacturing facilities, shipping terminals, and outdoor area security boundaries. Delivering a powerful 115,000 initial lumens of clean 3700K neutral white light, this compact lamp features a durable clear **BT37 hard glass envelope layout** that is significantly slimmer than traditional bulbous BT56 shapes. Outfitted with a heavy-duty E39 mogul screw base and certified for universal burning orientations, it serves as a rugged maintenance solution driven by matching ANSI standard M47 control gear.

ADL Supply Expert Application & Replacement Guide
The GE MVR1000/U/BT37 (18205) lamp is a highly compact, high-wattage industrial maintenance standard specified heavily for low-profile industrial high-bays, distribution hubs, heavy manufacturing lines, and commercial site lighting footprints. Engineered within a narrowed BT37 outer shield glass profile, it slips into restricted reflector hoods where bulkier standard BT56 lamps physically cannot clear the housing contours, offering facility managers immense lumen output alongside streamlined installation space parameters.
Critical Ballast Tuning and Mandatory Enclosed Safety Guidelines: This 1000-watt discharge capsule operates exclusively on an industry-standard ANSI M47 probe-start magnetic ballast network. Attempting to cross-wire this lamp onto newer pulse-start control gear (M141 tracking blocks) or high-pressure sodium choke blocks will prevent ignition or induce rapid terminal short-circuits across the transformer coils.
Furthermore, maintenance crews must strictly enforce the **ANSI M47/E classification rule: this bulb is explicitly certified for Enclosed Fixtures Only**. It must be installed behind a sealed, tempered glass lens shield. Because the inner quartz arc tube operates under immense pressure and extreme temperatures ($1000^\circ\text{C}$), a non-passive end-of-life structural failure (arc explosion) will drop white-hot shards if run inside open-face high-bays, creating severe building fire risks. Ensure the 39mm wide E39 Mogul base threads tightly into the socket to handle heavy runtime vibration cycles.

Verify Before Ordering
Universal Operating Orientations vs. Runtime Degradation — California Shipping Bans
This lamp features a Universal burn designation, allowing it to ignite at any mounting angle. However, operating the bulb horizontally or in specialized positions bows the internal plasma arc line: vertical installation yields 115,000 initial lumens and a 12,000-hour life, while horizontal orientations reduce values to 105,000 initial lumens and a 9,000-hour average rated life. Sizing calculations should plan for these boundary conditions prior to layout sweeps.
State Delivery Restriction: Due to California Title 20 efficiency regulations, this high-wattage tungsten-halogen or high-intensity mercury-vapor derivative lamp cannot be legally sold or shipped to residential or commercial destinations inside California. |

Operation, Safety & Mounting Compliance
High-Pressure Strike Core and Hot Restrike Intermission Windows
Following initial cold system ignition strikes from the core-and-coil ballast, this quartz capsule requires an initialization window of 5 to 7 minutes to fully gasify internal chemical elements and settle into its stable 3700K visual profile. If a brief voltage sag or temporary power interruption drops the circuit track loop during operational shifts, a mandatory hot restrike cool-down block of exactly 15 minutes must be strictly observed. This enables internal arc chamber pressures to relax entirely before the high-voltage ballast can safely re-strike the gas column.
UV Suppression Warnings and Casing Integrity Maintenance
This lamp can cause serious skin burns and eye inflammation from shortwave ultraviolet (UV) radiation if the clear BT37 outer glass envelope scratches, punctures, or micro-cracks during active cycles. National life safety codes mandate turning off the circuit breaker and replacing the bulb immediately if the outer envelope is compromised. Never handle the outer glass with bare skin; hands leave tracking alkaline body oils that fuse chemically to the hard glass wall under extreme operating currents, creating thermal hotspots that prompt early structural fractures.
