Product Overview

GE LED Tube Type A T8 4ft 15W 3500K – LED15ET8/G/4/835
The GE LED15ET8/G/4/835 Type A LED Tube is a 4ft-foot, 15W bare-lamp-wattage T8 replacement lamp rated at 2,200 initial lumens on a Normal Ballast Factor (0.88 BF) fixture, in 3500K 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.

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 15W/1,850 lm on a Low BF (0.78) ballast up to 23W/2,950 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 4ft 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 4ft (48 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
