GE LED Tube Type B T8 4ft 13W 4000K covRguard - 93154590-LED13BDT8/G4/840XL/CVG

GE LED Tube Type B T8 4ft 13W 4000K covRguard – LED13BDT8/G4/840XL/CVG

The GE LED13BDT8/G4/840XL/CVG Type B LED Tube is a 4-foot, 13W double-ended T8 replacement lamp rated at 1,950 initial lumens and 4000K color temperature. It ships with a factory-sealed covRguard® polycarbonate sleeve bonded to the glass tube, giving it shatter protection and NSF Food Zone acceptance that the bare-glass version of this wattage and CCT does not carry. 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 48-inch, 13W 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.

The covRguard® sleeve on this SKU is factory-bonded to the glass tube rather than a field-installed accessory, so it adds shatter containment and NSF Food Zone acceptance without a separate sleeve or fixture guard purchase — relevant for food prep, processing, or storage areas where a broken bare-glass tube would be a contamination risk.

Compatible Applications

• Retrofitting 4ft T8 fluorescent fixtures 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
• Food processing, prep, or storage areas requiring NSF Food Zone acceptance and shatter-contained lamps

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 (48 in MOL) version; do not substitute across lengths in this 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 coating 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
• The covRguard® sleeve provides shatter containment but does not eliminate the need for careful handling during installation

Compliance

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