Ushio 1001108 JR12V-10W/NFL21/FG 172735

The Ushio Eurostar 1001108 JR12V-10W/NFL21/FG Lamp is a commercial-grade, ultra-low-wattage halogen reflector capsule engineered for precision architectural accenting and shallow display showcases. Operating at 10 watts on a 12V low-voltage current line, this high-efficiency MR16 spotlight projects a tightly controlled 21° narrow flood beam spread yielding 550 center beam candlepower (CBCP). Outfitted with an industry-standard GU5.3 bi-pin base and a premium titanium oxide coated reflector shell, it incorporates a clear front safety glass face and an integrated UV-cut capsule to ensure a flawless 100 CRI color profile over an extended 4,000-hour rated average life.

ADL Supply Expert Application & Replacement Guide

The Ushio Eurostar JR12V-10W/NFL21/FG is a highly specialized low-wattage accent lighting standard heavily specified for fine jewelry display counters, museum glass cases, high-end retail cabinetry, hospitality focal wall wash structures, and low-voltage outdoor landscape spotlight accents. Precision manufactured in Japan, this lamp features a multi-layer titanium oxide dichroic coating across its reflector body. This specialized formulation locks down color consistency over the entire life cycle of the lamp—reflecting crisp, brilliant visible light directly forward while allowing heat and infrared radiation to exit safely through the open back of the reflector shell to prevent heat buildup on delicate merchandise.

Critical Voltage Identification Note for Field Installers: This bulb runs on a dedicated **12-volt low-voltage input circuit and is outfitted with standard GU5.3 straight bi-pins**. It cannot be integrated into standard 120V line-voltage tracks unless a compatible electronic or magnetic step-down transformer intermediary is utilized. Direct-wiring this lamp onto raw line currents will prompt immediate tungsten filament destruction and introduce a serious short-circuit hazard. Its premium C-8 axial filament layout offers enhanced mechanical resistance against systemic track vibrations, allowing for stable universal burning operations at any mounting angle.

Operation, Safety & Mounting Compliance

High-Temperature Thermal Boundaries and Handling Care

Because high-output low-voltage halogen capsules reach intense internal operating temperatures, always isolate step-down primary transformer feeds and permit a minimum 15-minute cool-down intermission before handling. Never touch the front clear glass face or the reflective dichroic shell with bare skin. Human fingers deposit microscopic body oils that bond to the quartz during rapid heating cycles, generating intense localized hot spots that trigger premature devitrification, micro-fracturing, and accelerated envelope rupture. Clean meticulously with isopropyl alcohol if accidental baseline skin tracking takes place.

Material Protection via FadeBlock™ Integrated UV Shielding

This Ushio module features an advanced UV-cut quartz tube wrapper engineered to filter out shortwave ultraviolet emissions. This critical screening prevents early bleaching, discoloration, and material deterioration down delicate museum art canvas grids, jewelry display cabinets, or high-end fabric store apparel rows, making it fully approved for continuous commercial project runs.
