Product Overview

The Sylvania 54174 50MR16/IR/NFL25/C 12V is a 50W 12V MR16 halogen lamp delivering 3000K Warm White output with a 25° Narrow Flood (NFL25) beam pattern. The IR (Infrared Reflecting) series uses a dichroic filter coating that reflects infrared energy back through the filament, reducing heat at the beam face while maintaining the same lumen output at lower wattage compared to standard lamps. Ideal for heat-sensitive merchandise, food display, and retail accent applications. A narrow flood beam balances intensity and coverage for display cases, wall washing, and retail accent.

Transformer required: This is a low-voltage (12V) lamp. It requires a compatible magnetic or electronic 12V transformer. Do not connect directly to 120V or 240V line voltage.

Applications

Accent and display lighting – Display case lighting, merchandise highlighting, and wall washing in retail and gallery environments.
IR technology — heat-sensitive merchandise – Infrared reflecting technology reduces heat at the beam face — ideal for food display, floral, and heat-sensitive merchandise.
Retrofit replacement – Drop-in replacement for MR16 GU5.3 fixtures. Confirm beam angle and wattage before ordering.

Safety and Installation

12V transformer required. This lamp operates at 12V only. Connecting to 120V or 240V line voltage will destroy the lamp and may cause fire or injury.
Do not touch the lamp envelope with bare hands. Skin oils cause hot spots leading to premature failure. Use clean gloves or a lint-free cloth.
Allow 15-minute cool-down before handling.
Use only in enclosed or open fixtures rated for MR16 lamps.
