GE LED Tube Type A T8 3ft 10.5W 4000K - 35788-LED11ET8/G/3/840

GE LED Tube Type A T8 3ft 10.5W 4000K – LED11ET8/G/3/840

The GE LED11ET8/G/3/840 Type A LED Tube is a 3ft-foot, 10.5W bare-lamp-wattage T8 replacement lamp rated at 1,600 initial lumens on a Normal Ballast Factor (0.88 BF) fixture, in 4000K color temperature. As a Type A lamp, it runs on the fixture's existing electronic fluorescent ballast — no rewiring is required, but actual output varies with the ballast's factor, and the fixture's ballast must be on GE's compatibility list before this lamp is installed.

Technical Specifications

Product Overview

GE's Type A T8 tubes are built to run on the fixture's existing electronic fluorescent ballast, so there is no rewiring and the existing sockets are reused as-is. That convenience comes with a trade-off the ballast-bypass Type B line doesn't have: actual system wattage and lumen output shift with the ballast's factor, from 11.5W/1,350 lm on a Low BF (0.78) ballast up to 18W/2,150 lm on a High BF (1.18) ballast, so the same lamp performs differently depending on which ballast it's paired with.

Because the lamp depends on the existing ballast, GE maintains a published compatibility guide (www.LED.com/LEDTUBES-ballast-compatibility) that should be checked against the fixture's ballast model before ordering — an incompatible or aging ballast can affect starting, flicker, or lamp life in ways a ballast-bypass lamp would never encounter.

This SKU carries DLC Qualified Products List status, which matters for buyers pursuing a utility rebate on the retrofit. Not every wattage and CCT combination in this line is DLC listed, so rebate-driven projects should confirm this exact model number, not assume the family qualifies.

Compatible Applications

• Retrofitting 3ft T8 fluorescent fixtures with a compatible electronic Instant Start or Program Start ballast, without rewiring
• Projects where minimizing labor/installation time matters more than eliminating the ballast as a future maintenance item
• Damp-location fixtures — the tube itself is Damp Location rated, though the fixture's own rating still governs the installation

Before Ordering – Verify

• Confirm the fixture's ballast is on GE's compatibility list (www.LED.com/LEDTUBES-ballast-compatibility) — unlike a Type B lamp, this one depends entirely on the existing ballast
• Confirm tube length — this is the 3ft (36 in MOL) version; do not substitute across lengths in this family
• Expect system wattage and lumen output to vary with the ballast's factor (Low/Normal/High) — quote using the fixture's actual ballast factor, not just the Normal BF figures
• If dimming is required, confirm the ballast is on the compatible dimming ballast list before specifying
• 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
• No rewiring is performed for a Type A lamp, but confirm the existing ballast and sockets are in good condition before relamping
• Dispose of end-of-life lamps as non-hazardous waste per local regulations

Compliance

• UL 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
