Our take on the Philips T12 48" 39W 4100K Fluorescent Tube

This is a 48-inch T12 fluorescent tube rated 39 watts with a single-pin Fa8 base and a 4,100K cool white color. It is a slimline lamp, meaning it runs without an internal starter and needs a matching ballast or fixture. Philips' ALTO line is known for lower mercury content than standard tubes. It suits owners replacing a burned-out tube in a slimline fixture, not shoppers switching to LED.
