Product Overview

GE LED Tube Type B T8 8ft 43W 3500K – LED43BDT8/G8/835
The GE LED43BDT8/G8/835 Type B LED Tube is an 8-foot, 43W double-ended T8 replacement lamp rated at 5,000 initial lumens and 3500K color temperature, using an R17d base. 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.

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, 43W 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.
Like the rest of the 8ft R17d family, this lamp is not on the DLC Qualified Products List, so a rebate-driven retrofit should confirm eligibility before specifying it. Confirm the R17d base and 96-inch MOL match the fixture — this lamp is not interchangeable with the shorter G13/2G13 lengths elsewhere in the line.
Compatible Applications
- Retrofitting 8ft T8 fluorescent slimline/HO fixtures with an R17d base that are being converted to ballast-bypass LED
- 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 R17d single-pin base and 96-inch (8ft) MOL — this lamp is not interchangeable with G13/2G13-based lengths elsewhere in the Type B line
- Confirm supply voltage matches 120-277V
- Sockets can be shunted or non-shunted — no socket replacement is required for this double-ended Type B design
- This SKU is not DLC Listed — do not quote it into a rebate-dependent project without confirming an alternate qualifying model
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
- Not currently on the DLC Qualified Products List
