The longer-format F42T8 bypass tube for the fixtures that don't take a standard 4ft lamp. Direct wire, no ballast. Available in 4000K high-output or 5000K, with a 2-pin configuration option for fixtures wired that way — check the lamp holder on the existing fixture before ordering so the pin count matches.
