GE LED Tube Type B T8 8ft Fa8 42W 4000K 120-347V - 93309185-LED42BDT8/G8/Fa8/840/120-347

GE LED Tube Type B T8 8ft Fa8 42W 4000K 120-347V – LED42BDT8/G8/Fa8/840/120-347

The GE LED42BDT8/G8/Fa8/840/120-347 Type B LED Tube is an 8-foot, 42W double-ended T8 replacement lamp rated at 5,500 initial lumens and 4000K color temperature, using an Fa8 recessed single-contact base and built for 120-347V branch circuits. The Fa8 base distinguishes it from GE's R17d-based 8ft Type B tubes of the same wattage class — the two bases are not interchangeable, so fixture base type has to be confirmed before ordering. As a Type B lamp, it is a ballast-bypass design: the fixture must be rewired to run the tube directly off line voltage, and it cannot be installed into a fixture that still has its fluorescent ballast in the circuit.

Technical Specifications

Product Overview

GE's Type B T8 tubes bypass the ballast entirely, which is why the fixture has to be rewired to run line voltage directly to the lamp sockets before this 96-inch, 42W tube is installed. Removing the ballast from the circuit eliminates it as a future point of failure and as a stocked spare part, but it also means this lamp will not light, and can pose a hazard, if it is dropped into a fixture that has not been converted.

The internal safety switch and misapplication circuit built into this lamp are there specifically to reduce risk during that rewiring step and during future relamping by someone unfamiliar with the fixture's ballast-bypass status. GE also offers an optional in-line fuse kit (order code 39017), sold separately, for facilities that want an extra layer of protection against a future relamp mistake.

This 120-347V, Fa8-base version is a distinct SKU from GE's R17d-base 8ft Type B tubes: the two use different single-pin bases and are not interchangeable at the socket. Like the rest of this 120-347V Fa8 family, confirm the fixture's actual base type and branch-circuit voltage before ordering.

Compatible Applications

• Retrofitting 8ft T8 fluorescent fixtures with an Fa8 recessed single-contact base that are being converted to ballast-bypass LED
• Facilities on 120-347V distribution, such as some Canadian and industrial 347V branch circuits
• Damp-location fixtures — the tube itself is Damp Location rated, though the fixture's own rating still governs the installation
• Open or enclosed fixtures already wired or being rewired for direct line voltage

Before Ordering – Verify

• Confirm the fixture has been rewired for ballast bypass — this lamp cannot power on, and may create a hazard, in a fixture still wired through its fluorescent ballast
• Confirm the fixture takes an Fa8 base, not R17d — GE sells both base types in this 8ft/42W 120-347V family and they are not interchangeable
• Confirm supply voltage matches 120-347V
• Sockets can be shunted or non-shunted — no socket replacement is required for this double-ended Type B design
• If the project depends on a utility rebate, verify this exact model number on the DLC Qualified Products List, not just the product family

Safety and Handling Guidelines

• Glass lamp — handle and store to avoid impact or breakage; do not use if the tube is cracked
• De-energize the fixture before installing or removing the lamp, and before performing the ballast-bypass rewiring
• Label the fixture as ballast-bypass / direct-wire so future relamps are not attempted with a standard fluorescent tube
• Dispose of the removed fluorescent ballast per local electrical waste regulations; it is not reused with this lamp
• This is an 8ft glass lamp — use two-person handling and appropriate support during installation to avoid dropping or flexing the tube

Compliance

• UL 1993 Listed for LED lamps
• Damp Location rated
• DLC Qualified Products List — confirm this exact model at designlights.org before relying on it for a rebate
