GE 41488 Q50MR16/CCG15

The GE ConstantColor® Precise™ 41488 (EXT/24V) Lamp is a premium, commercial-grade low-voltage tungsten halogen reflector spotlight engineered for specialized 24V architectural circuits, long-throw high-ceiling tracks, and premium retail showcase systems. Delivering a controlled, punchy 14° narrow spot beam spread, this high-performance MR16 capsule yields an intensive 8,500 center beam candlepower (CBCP). Outfitted with an industry-standard GX5.3 bi-pin base and an advanced multi-layer dichroic coating, it provides an extended 6,000-hour rated average service life while completely suppressing color drift or greenish aging tints over its operational lifespan.

ADL Supply Expert Application & Replacement Guide

The GE ConstantColor Precise 41488 (EXT/24V) lamp is an architectural and specialized retail lighting standard specified heavily across high-ceiling department galleries, hotel lobby maintracks, museum focal displays, and cruise ship marine lighting systems operating on centralized 24V power supplies. Engineered with an ultra-tight 14-degree narrow spot distribution, this module projects a highly concentrated beam profile across exceptionally long distances, delivering standard design illumination metrics over specific accents without creating light spill loops.

Critical 24V Operational Constraints and Open-Face Luminaire Restrictions: Electrical contractors must verify circuit parameters prior to checking out their cart: this is a specialized 24-Volt low-voltage lamp. Operating this module on standard 12V tracks will reduce filament temperatures, rendering it completely dim and non-functional.

Furthermore, because this lamp features an **Open-Face configuration with no integrated front protective safety glass cover lens, national life safety and electrical codes dictate installation strictly inside fully enclosed luminaires outfitted with a secondary tempered glass cover shield**. Running this pressurized quartz capsule within open track canisters or exposed ring gimbals is strictly prohibited. Sizing infrastructure over 24-volt lines cuts systemic amperage loop requirements exactly in half compared to 12V systems (drawing a steady 2.08 Amps), preventing voltage drops across extended contractor cable runs. Ensure the multi-layer dichroic glass reflector back remains well-vented to allow back-routed infrared heat to escape safely.

Operation, Safety & Mounting Compliance

Low-Voltage Transformer and Dimming Controls

This 50-watt capsule operates strictly on low-voltage 24V lines driven by high-quality electronic or magnetic core-and-coil step-down transformers. Check your transformer nameplate under load to confirm total available wattage parameters safely accommodate the 50W continuous load draw. This module is 100% dimmable to low light levels—to prevent filament buzzing or flicker loops across the system, ensure that your wall dimmers are specifically certified for low-voltage lighting control (electronic low-voltage ELV or magnetic low-voltage MLV tracking, matching your transformer's internal circuit framework).

Handling Rules and Casing Maintenance

Never handle the internal clear quartz capsule or reflector face with bare hands during installation loops. Human fingers automatically deposit microscopic alkaline body oils that fuse chemically to the quartz lens during rapid heating cycles. This containment creates localized hot spots, prompting envelope clouding, micro-fracturing, and accelerated pressure breakdown. Installers must execute re-lamping sweeps using clean cotton tech gloves, a microfiber lint-free wipe, or its protective cardboard wrapper sleeve. Meticulously wipe the bulb with isopropyl alcohol if skin tracking occurs. Let the track head cool down for 15 minutes before servicing components to prevent contact skin burns.
