Topstar L48T8-840-14P-G7S-DW 4ft T8 LED Tube 14W 4000K Ballast Bypass

Product Overview

The Topstar L48T8-840-14P-G7S-DW is a 4-foot ballast-bypass LED T8 replacement lamp engineered for commercial retrofit lighting applications requiring energy-efficient fluorescent replacement technology. Operating on 120–277VAC with 14W power consumption, the lamp delivers 1900 lumens at a 4000K neutral-white color temperature while supporting both double-end and optional single-end direct-wire installation configurations for flexible retrofit deployment in offices, retail spaces, schools, utility facilities, warehouses, and general commercial interiors.

Key Features & Design

• Functionality: Ballast-bypass LED T8 replacement lamp providing energy-efficient fluorescent retrofit illumination with direct-wire installation compatibility for commercial lighting upgrades.
• Installation context: Designed for retrofit installation in existing T8 fluorescent fixtures in offices, retail stores, schools, warehouses, utility buildings, commercial interiors, food-service environments, and general indoor lighting applications. Compatible with both shunted and non-shunted lamp holders depending on installation configuration.
• Notable specifications: 1120–277VAC universal input; 14W power consumption; 1900 lumen output; 4000K neutral-white color temperature; CRI 80; efficacy up to 135–150 LPW product-family performance; G13 bi-pin base; 160° beam angle; frosted PET-coated shatter-protected tube construction; double-end direct-wire operation with optional single-end wiring capability; non-dimmable operation; 50,000-hour rated lifespan; DLC 4.2 listed; UL Classified; NSF-rated shatter protection for food-preparation areas; suitable for damp locations when installed in properly rated fixtures.
• Contractor-relevant details: Double-end ballast-bypass wiring minimizes installation labor and often eliminates the need for non-shunted socket replacement during fluorescent retrofit projects. Optional single-end installation capability provides additional field flexibility, while the integrated universal-voltage driver simplifies deployment across varying commercial electrical systems. PET-coated shatter-protected construction supports food-service and commercial safety compliance requirements.

Performance / Benefits

In commercial retrofit lighting applications, the L48T8-840-14P-G7S-DW delivers efficient neutral-white illumination while significantly reducing energy consumption compared to traditional fluorescent T8 lamps. Its ballast-bypass direct-wire configuration eliminates ballast-related maintenance failures and compatibility issues, supporting improved long-term reliability and reduced operating costs. The wide 325° beam angle and frosted diffuser construction provide broad, uniform light distribution, while the PET-coated shatter-protected tube design enhances durability and application flexibility across demanding commercial and institutional environments.
