Our take on the Philips 40w 6500k T12-6U FB40DX6/12 Daylight U-Tube T12 Fluorescent Light Bulb

The Philips FB40DX6/12 is a 40W T12 U-tube fluorescent lamp with 6-inch leg spacing, made for 2x2 troffers and other fixtures that take bent bi-pin tubes. It produces 2,250 lumens at 6500K daylight with a CRI of 90, so colors look close to natural and the light reads cool and bright. Rated life is 18,000 hours, and it is low-mercury and TCLP compliant. Against generic U-bend tubes, its edge is the high CRI and the full 6-inch leg spacing that fits standard 2x2 commercial fixtures; it is a straight replacement, not an upgrade in efficiency.
