A 22-watt T9 circline fluorescent tube that produces 1,100 lumens of cool white light. Its ring shape spreads light in a broad circle, which suits ceiling fixtures in garages, basements and utility rooms better than a narrow linear tube. It is a straightforward replacement for existing circline fixtures, not an upgrade to LED. Expect the usual fluorescent trade-offs: a warm-up period, lower cold-weather output and a ballast that must match the tube.
