GE 93138429 LED13ABT8/G4/840 13W 4ft T8 LED Glass Tube 4000K G13 Type A+B Dual Mode | 1950 Lumens | CRI 80 | G13 | 50,000 Hours

The GE 93138429 LED13ABT8/G4/840 is a 13W, 4-foot UL Type A+B dual-mode LED glass T8 tube. It delivers 1950 lumens at 4000K with a CRI of 80, and can be installed on a compatible existing ballast (Type A) or converted to direct line-voltage ballast bypass (Type B) if the fixture is later rewired. Verify the G13 base, 4-foot T8 lamp configuration, and which operating mode (Type A or Type B) the fixture will use before ordering.

Technical Specifications

Product Overview

The GE Type A+B Dual Mode LED Glass Tube offers installation flexibility: it can run off a compatible existing ballast at initial installation (Type A) and later run directly off line voltage (Type B) should the ballast fail or be found incompatible, without needing to source a different lamp. To operate the lamp in Type B mode the fixture must be rewired to bypass the ballast.

The lamp works with either shunted or unshunted sockets in Type B double-ended mode and includes built-in safety protection for installers and end users. Performance is design/typical data measured on Normal Ballast Factor (0.88); actual performance in Type A mode may vary with ballast model, age, and ballast factor (Low 0.78, High 1.18).

Compatible Applications

• Commercial 4ft T8 fluorescent retrofit applications, either ballast-driven or ballast-bypass
• Fixtures with a compatible existing ballast (Type A mode) as an initial, no-rewire installation
• Fixtures rewired for direct line voltage (Type B mode) once the ballast is retired or found incompatible
• Open or enclosed fixtures in damp locations
• Maintenance and MRO inventory programs where stocking one dual-mode SKU covers both operating modes

Before Ordering – Verify

• Confirm G13 base and 4-foot T8 lamp configuration.
• Confirm which mode the fixture will use – Type A (existing ballast) requires ballast compatibility confirmation at www.LED.com/LEDTUBES-ballast-compatibility; Type B requires fixture rewiring.
• Do not install LED and fluorescent lamps in the same fixture.
• This lamp is not dimmable – confirm dimming is not required before ordering.
• Confirm current DLC QPL qualification for this specific model at www.designlights.org/search before quoting rebate eligibility.

Safety and Handling Guidelines

• Turn power off before installation, inspection, or maintenance.
• Install and operate in compliance with NEC, UL requirements, and all applicable codes and regulations.
• Insert and align tubes properly in lamp holders – partial insertion can cause poor contact, arcing, and localized overheating.
• To convert to Type B operation, the fixture must be rewired by a qualified electrician to bypass the ballast.
• Suitable for damp locations only – do not install where the lamp will come in direct contact with water.

Compliance

• cULus listed (UL 1993)
• DLC Listed – not all product variations are DLC qualified; confirm the specific model at www.designlights.org/search
• Damp location rated per UL 1993 environmental requirements
