The Satco S6500 is a 22-watt T9 circline fluorescent tube with a 4-pin G10Q base, an 8-inch ring, 4100K cool white light and roughly 1,100–1,200 lumens. It is a direct replacement lamp for fixtures built around 8-inch circline tubes, such as magnifier lamps, ceiling rings and task lights. Its 62 CRI is low even for fluorescent, so colors look flat compared with tri-phosphor circlines, and its 11,000–12,000 hour rating is ordinary for the category. Buyers choose it for the specific base and size, not for light quality.
