Product Overview

The Philips 533372 is a MasterClass four-foot T8 LED tube intended for use in compatible commercial fluorescent fixtures. The lamp is classified as Type A / Type C, meaning it may operate either on an approved existing fluorescent ballast or with an approved dedicated LED driver.

The tube produces 2,400 lumens from 15.5 watts, providing nominal efficacy of approximately 155 lumens per watt. Its 3500K color temperature delivers a neutral-white appearance suitable for compatible commercial, institutional, retail, office, and industrial lighting systems.

Philips identifies more than 15,000 InstantFit lamp-and-ballast combinations across its InstantFit portfolio; however, compatibility must still be verified for this exact lamp and the specific ballast or LED driver installed in the fixture.
