Product Overview
The Ushio 1000605 FSH JCV120V-125WB is a 125W 120V single-ended halogen JC photo-optic and SSTV lamp engineered for professional audio/visual projection, studio lighting, stage spotlights, and photo-optic equipment. Delivering 3000K warm white output at 100 CRI through a G5.3 2-pin bi-pin base, this ANSI FSH-coded lamp provides a 200-hour calibrated service life in approved enclosed optical fixture assemblies — with a base-down only burn position restriction.

ADL Supply Expert Application & Replacement Guide
The Ushio FSH JCV120V-125WB (Catalog 1000605) is primarily used by AV equipment technicians, studio lighting service teams, and stage lighting personnel as the replacement lamp in 125W 120V projectors, studio fixtures, stage spotlights, and photo-optic equipment where the ANSI FSH code is the equipment specification. This lamp operates on standard 120V line voltage — no transformer is required. The /B suffix in the lamp designation indicates base-down burn position only — this lamp must be installed with the base (pins) pointing downward; horizontal or base-up mounting is not approved and will affect filament orientation and lamp life at these operating temperatures. The G5.3 2-pin bi-pin base uses standard 5.3mm round pin spacing — confirm the fixture socket is G5.3 before ordering. The 200-hour calibrated service life is a precision parameter of the high-output photo-optic halogen platform — production and studio facilities should track runtime hours and maintain a replacement inventory to avoid lamp failure during active shoots or performances.
Before You Order
| Verify Before Ordering Base-Down Burn Position Only — Not Universal | G5.3 Socket | Confirm ANSI FSH | Enclosed Fixture Required This lamp is approved for base-down burn position only — horizontal or base-up mounting is not permitted. Confirm your fixture installs this lamp with the base pointing downward. Confirm ANSI code FSH matches your equipment specification. Confirm G5.3 bi-pin socket. Enclosed fixture required. Allow 15-minute cool-down before relamping. |

Operation, Safety & Mounting Compliance
Base-Down Burn Position, 120V Line Voltage & Quartz Handling
The base-down burn position restriction is encoded in the "/B" suffix of the lamp designation JCV120V-125WB — the lamp's filament is designed to operate with the base (pins) pointing downward relative to gravity. Operating this lamp in a horizontal or base-up position causes the filament to sag under gravity in a different plane than its design geometry, creating hot spots that accelerate premature envelope failure at these operating temperatures. Confirm the fixture and mounting bracket orient the lamp base-down before installation. This lamp operates on standard 120V line voltage — no transformer is required; verify supply voltage before installation. Never handle the quartz envelope with bare skin — skin oils create localized hot spots that accelerate premature envelope failure. If skin contact occurs, clean with isopropyl alcohol before powering the fixture. Allow a minimum 15-minute cool-down before relamping.
