Sylvania 41448 LED9.5T8L48/FG/841/BFG2 9.5W 4FT T8 LED Tube – 4100K, 1600 Lumens, Type B, 120–277V, Dimmable

Sylvania 41448 LED9.5T8L48/FG/841/BFG2 – 9.5W 4FT T8 LED Tube | 4100K | 1600 Lumens | Type B | 120–277V

The Sylvania 41448 LED9.5T8L48/FG/841/BFG2 is a 9.5-watt, four-foot LEDlescent ballast-free T8 lamp designed for direct-wire Type B installation. It produces 1,600 lumens at 4100K with a CRI of 82 and operates directly from 120–277V after the fluorescent ballast is disconnected from the lamp circuit. The frosted soft-glass tube uses G13 medium bi-pin bases, supports double-ended wiring, and is compatible with both shunted and non-shunted lampholders. This lamp is dimmable with approved equipment. Please verify the exact product number, wiring configuration, voltage, lampholder condition, fixture type, dimensions, dimmer compatibility, and installation requirements before ordering.

Technical Specifications

Product Overview

The Sylvania 41448 LEDlescent T8 is a high-efficiency Type B retrofit lamp designed to operate without a fluorescent ballast. During installation, the ballast is disconnected from the lamp circuit and line voltage is supplied to opposite ends of the tube using the manufacturer-approved double-ended wiring configuration.

The lamp produces 1,600 lumens from 9.5 watts, providing a manufacturer-listed efficacy of 168 lumens per watt. Its 4100K cool-white output and frosted glass construction support uniform general illumination in compatible commercial, institutional and industrial fixtures.

A built-in safety circuit prevents current from passing through the lamp when only one end is engaged in a socket, reducing potential shock risk during proper installation. The design also works with both shunted and non-shunted G13 lampholders, so a socket replacement is not necessarily required when the existing lampholders are in good condition.

Compatible Applications

• General illumination
• Cove lighting
• High-bay fixtures designed for four-foot T8 lamps
• Parking garages
• Tunnels and underpasses
• Commercial and institutional linear lighting
• Fixtures converted from 32W fluorescent T8 lamps
• Occupancy-sensor-controlled lighting systems

Before Ordering – Verify

• Product number: Confirm Sylvania NAED 41448.
• Ordering abbreviation: Verify LED9.5T8L48/FG/841/BFG2.

• Dimensions: Confirm the fixture accepts a tube approximately 47.72 inches long and 1.02 inches in diameter.
• Temperature: Keep operation within -20°C to 45°C.
• Packaging: One lamp per SKU and 25 lamps per case.

Safety and Installation Guidelines

• Ballast-bypass wiring is required. This lamp must be installed according to the LEDVANCE Type B wiring instructions.
• Disconnect and lock out electrical power before inspection, wiring, installation or removal.
• The fluorescent ballast must be disconnected from the lamps.
• If the ballast remains physically inside the fixture, cap all unused ballast wires individually.
• Do not expose wiring to sharp sheet-metal edges or other abrasive surfaces.
• Do not drill or alter open holes in wiring or electrical-component enclosures during installation.
• Do not install LED lamps and fluorescent lamps in the same fixture.
• Verify all lampholders and wiring connections are in good condition.
• Affix the manufacturer-supplied luminaire warning label to the fixture to maintain the retrofit safety identification.
• Confirm the correct double-ended electrical connections before restoring power.
• Use only in dry or damp locations without direct water exposure.
• Do not use in vapor-tight or sealed luminaires.
• Installation should be performed by qualified electrical personnel in accordance with the NEC and applicable codes.
