Overall winner: Sunlite 4-pin FML27/65K quad tube compact fluorescent lamp
Key Differences
Sunlite A produces much higher lumen output at low wattage and uses a GX10q4 quad-tube compact design in daylight 6500K, making it suited for bright task lighting and fixtures that accept GX10q4. Circle B is sold as a 6-pack of 24-inch T8 tubes in warm white 3000K, better for multiple standard T8 fixtures and situations preferring warmer light; Circle offers a better per-unit price tier while Sunlite scores higher on brightness and has many more reviews
