This is a Philips 85-watt T12 fluorescent tube, 72 inches long, with a recessed double contact (R17d) base. It runs at 6500K daylight and is a high-output lamp, so it puts out more light than a standard-output tube of the same length. It is built for large commercial and industrial fixtures, such as high-bay and strip lights in shops, warehouses and garages. The ALTO designation means it is a low-mercury lamp. Few rivals match this combination of length, output and daylight color, and the 4.9 rating from 36 buyers suggests owners get what they expect.
