Philips 543496 T12 Linear Fluorescent Bulb 20W

Product Description

The PHILIPS 543496 is a 20-watt T12 linear fluorescent tube with a bi-pin base, designed for standard fluorescent fixtures in residential and commercial settings. This lamp delivers broad-spectrum general-purpose illumination and fits directly into common T12 bi-pin lamp holders without modification. Electricians and facility maintenance technicians use this bulb as a direct replacement in troffers, strip fixtures, and wraparound luminaires. At 20 watts, it is suited for lower-output T12 applications where direct lamp substitution is the primary goal. The T12 designation indicates a 1.5-inch tube diameter, which is standard for this lamp family.

This bulb is appropriate for a wide range of general lighting applications including offices, utility rooms, garages, workshops, storage areas, and light commercial spaces. It is sold individually and packaged in a case quantity of 12 units, making it practical for stocking on service trucks or in supply rooms. Both residential maintenance and commercial facility teams will find this lamp suitable for routine lamp replacements in existing T12 fixture installations.

Installation Notes

Lamp replacement should be performed by a qualified electrician or trained maintenance technician. Always de-energize the fixture at the circuit breaker before handling lamps or accessing ballast components. Verify that the existing ballast is rated for a 20-watt T12 lamp before installation. Handle the tube carefully to avoid breakage, as fluorescent lamps contain mercury and must be disposed of in accordance with local environmental regulations.
