ADL Supply Expert Application & Replacement Guide
The GE F15T8/CW (Order Code 10142) is primarily utilized by electrical contractors and facility maintenance teams servicing 18-inch T8 fluorescent fixtures in under-cabinet task lighting assemblies, display case interiors, equipment lighting panels, and specialty short-format fixture applications where the standard 48-inch T8 format is too long to seat correctly. This lamp requires a ballast specifically rated for 15W 18-inch T8 operation — GE recommends ballast model GE #80819 (GEM220TS120DIY) as the compatible platform for this lamp. The G13 medium bi-pin base is physically the same format as standard 4-foot T8 lamps, but the 17.78-inch overall length means this lamp will only seat correctly in fixtures designed for the 18-inch lamp class — confirm the fixture accepts an 18-inch T8 before ordering. The CRI of 60 reflects the soda lime phosphor construction of this economy-tier T8 — verify CRI requirements for the application before ordering if color rendering accuracy is a specification requirement.
Before You Order
| Verify Before Ordering 18-Inch T8 Format — Requires 15W T8 Ballast | Not a Standard 48-Inch T8 This is an 18-inch T8 lamp (17.78" MOL) — it is not interchangeable with standard 48-inch T8 lamps. Confirm your fixture is designed for the 18-inch lamp format and that your ballast is specifically rated for 15W T8 operation. GE recommends ballast GE #80819 (GEM220TS120DIY) for this lamp. Confirm 4100K cool white matches your application before partial re-lamping. |

Operation, Safety & Mounting Compliance
Ballast Compatibility & 18-Inch Format Specificity
The 15W 18-inch T8 format operates at different electrical parameters than the standard 32W 48-inch T8 and requires a ballast specifically listed for 15W T8 operation. GE-recommended ballast GE #80819 (GEM220TS120DIY) is the matched control gear platform for this lamp. Do not attempt to operate this lamp on a ballast rated for a different T8 wattage or tube length. The 17.78-inch overall length physically prevents correct installation in standard 48-inch T8 fixture lampholders — this lamp is exclusively for 18-inch T8 fixture platforms.
Mercury Content & Disposal
This lamp contains mercury and must be recycled through a certified lamp recycling program in compliance with applicable federal, state, and local environmental regulations — do not discard in standard municipal solid waste. State shipping restrictions may apply in CA, CO, HI, ME, MN, OR, RI, and VT — confirm shipping eligibility before ordering.
