Lumina RGB adds lighting to Mushkin's Redline DDR5 kits without changing the underlying speed grade — both capacities in this family run identical timings, so the RGB top plate is the distinguishing feature rather than anything electrical.
This one is 2×16GB, 32GB total, at 6000 MT/s CL30. With one speed bin across the family, the decision between the two listings is simply how much DDR5 the build calls for, since 6000 MT/s and CL30 don't vary between them.
This is UDIMM for desktop boards with RGB header or software support; the motherboard controls how the lighting is addressed, and 6000 MT/s still depends on enabling the XMP or EXPO profile in BIOS rather than the module's default clock.
