The G E LIGHTING 66655 is a 40-watt T12 fluorescent tube bulb sold in a 2-pack, designed for kitchen and bath lighting applications. Each tube delivers 2,900 lumens at a 3,000 Kelvin color temperature, producing warm white light well suited to task-oriented spaces. A Color Rendering Index of 87 means colors appear accurate and true under these lamps. The medium bi-pin base is the standard connection type for residential and light commercial fluorescent fixtures. Rated at 20,000 hours of lamp life, this tube reduces replacement frequency on high-use fixtures. Licensed electricians and maintenance technicians are the typical installers.
These tubes are intended for kitchen and bath fluorescent fixtures that accept a 40-watt, T12 medium bi-pin lamp. The 48-inch maximum overall length and 1.5-inch bulb diameter confirm fitment before installation. The 3,000 K output is a common specification for vanity strips, under-cabinet fluorescent housings, and utility fixtures in residential and light commercial settings. Each package contains 2 lamps under manufacturer part number F40/KBP/ECO/2P, so the package quantity noted in supplier data reflects multi-pack case ordering.
Designed as a replacement for 40-watt T12 medium bi-pin fluorescent fixtures, including kitchen and bath strip lights and vanity fixtures that accept a 48-inch tube with a 1.5-inch bulb diameter.
Fluorescent tube replacement should be performed by a qualified electrician or a knowledgeable maintenance technician. De-energize the fixture at the breaker before removing the existing lamp or accessing the tombstone sockets. Verify that the existing ballast is rated for 40-watt T12 operation and that the lamp base orientation matches the fixture socket before seating the new tube. Dispose of spent fluorescent lamps in accordance with local regulations, as tubes contain mercury.
