I got these 6 inch sample strips in 3200K and 5600K from Waveform some time ago, just forgot to post about them.
The short sample strips used to be free but now they include a 12V AC-DC adapter with it and the bundle costs $14. A 5 meter / 16ft strip is $109. The strips come with an easy to attach clip for the power supply cables.

-Available in 12V and 24V configuration, 15cm/6” samples only in 12V
–1500 lumens per meter
–95+ CRI and R9 >80 (R9 > 90 for tungsten)
I tested the strips with a bench power supply and measured the forward voltage vs. current. The output is very close to the specs if linearly scaled from 15cm to 1 meter. Remember that the output will diminish with longer strips due to voltage drop unless you feed in the power to the strip in several places.
-For the 3200K strip I got 1360 lumens per meter at 11.73V and 200mA for 15cm
-For the 5600K strip I got 1420 lumens per meter at 12.15V and 200mA for 15cm
For 1 meter the current would be ~1330mA.
Color rendering and tint is great on both. I measured these integrated at 200mA at slightly below 12V.

Tint doesn’t change much below rated voltage and low currents.
