Sylvania F20T12 Designer Soft White 24 inch

This fluorescent tube measures 24 inches in length and operates at 20 watts. It features a Medium Bi-Pin G13 base designed for compatible preheat fixtures. The Designer Soft White coating produces a warm 3000K colour temperature. Supplied as a case of four units for multi-lamp installations.

Preheat T12 interface and base compatibility

The lamp requires a preheat ballast circuit and will not operate on instant-start or rapid-start systems without correct wiring. Its G13 Medium Bi-Pin base fits standard T12 sockets but is not interchangeable with T8 or T5 pin spacing. Voltage and current draw are determined by the external ballast, not the tube itself. Verify fixture labelling before installation.

Case of four tubes for general lighting

Four tubes provide enough light sources for a small office, garage or retail display using multi-lamp troffers. The 20 watt rating limits output to modest ambient levels rather than high-bay tasks. Colour rendering suits general-purpose areas but may not meet critical inspection requirements. Additional tubes must be purchased in further cases of four.
