This is a 20-watt T12 fluorescent tube, 24 inches long, in a 4100K cool white color. It puts out about 1,200 initial lumens and is rated for 9,000 hours. The ALTO line is Philips' low-mercury version, so it meets disposal rules in many states. Its color rendering index of 62 is low, so colors look duller than under a tube with a CRI in the 80s. It suits under-cabinet and utility fixtures that take a 24-inch T12 tube, not kitchens or anywhere color accuracy matters.
