GE LED Tube Type B T5 4ft HO 25W 5000K - 93100295-LED25BDT5/G4/850

GE LED Tube Type B T5 4ft High Output (HO) 25W 5000K – LED25BDT5/G4/850

The GE LED25BDT5/G4/850 Type B LED Tube is a 4-foot, 25W double-ended T5 replacement lamp rated at 3,600 initial lumens and 5000K color temperature. As the High Output (HO) version of GE's T5 Type B line, it is built for the 4ft length where maximum lumen output per fixture matters. 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 T5 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 46-inch, 25W 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, ordered separately, for facilities that want an extra layer of protection against a future relamp mistake.

This SKU carries DLC Qualified Products List status, which matters for buyers pursuing a utility rebate on the retrofit; the 3ft and 2ft tubes in this line do not carry that listing, so rebate-driven projects should confirm length and DLC status together, not wattage alone.

Compatible Applications

• Retrofitting 4ft T5 fluorescent fixtures (HO or HE lamp/ballast combinations) 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 troffers, strip fixtures, and coolers/display cases 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 tube length — this is the 4ft (46.0 in MOL) version; do not substitute across the 2ft/3ft/4ft family
• 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
• 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 or sleeve 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

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
