This is a 32-watt circular fluorescent tube on a G10q 4-pin base, made to drop into ceiling fixtures and magnifier lamps that take a circline bulb. It puts out about 1,800 lumens of cool white light at 4100K and is rated for roughly 12,000 hours. The low CRI of 62 is the weak spot: colors look flat and skin tones dull next to a modern LED retrofit. It suits anyone keeping an older circline fixture alive, not someone shopping for light quality.

Owners of circline fixtures generally report these tubes fit and light as expected, and most are replacing a failed tube rather than choosing one fresh. Complaints center on color quality and on tubes that fail well short of the rated life.
Same performance characteristics. All fluorescent lamps need a small amount of mercury to operate efficiently and Philips has been working hard to reduce the mercury levels. We have always believed that a product can be good for the environment and provide the same or superior performance. This belief led to one of the industry's most innovative technologies. In 1995, Philips transformed the market by launching a line of linear fluorescent lamps featuring ALTO Lamp Technology.
