42 W GX24q-4 CFL for commercial fixtures

This 42 W plug-in CFL uses a 4-pin GX24q-4 base and produces 3200 lumens at a 3500 K neutral white colour temperature. It is built for fixtures that accept the F42TBX form factor and operates on a 120 V supply. The lamp suits both residential and commercial installations where a direct-fit replacement is required.

Amalgam technology and enclosed-fixture rating

Amalgam technology gives stable lumen output across a wide ambient temperature range and in any burn position. The bulb is rated for use in enclosed indoor and outdoor plug-in CFL fixtures, so it maintains performance where non-amalgam lamps would lose output. This makes it practical for recessed cans, wall packs and post-top luminaires.

15-year rated life with 82 CRI

Rated to last 15 years at three hours per day, the lamp delivers 3200 lumens with an 82 CRI for general-purpose colour rendering. Annual operating cost is 5.06 dollars at 11 cents per kWh under the same usage profile. It is not suited for dimming circuits, phase-cut controls or fixtures that require a 2-pin or alternative 4-pin base.
