Samsung is a Korean electronics company that also makes LEDs. Their main LED for flashlights is the 3535 which is very similar to the Cree XP-G. The "3535" name refers to the size of the LED which is 3.5mm x 3.5mm, but the model name seems to have changed to LH351A, along with some of the binning codes. The information below pertains to what they called the 3535 originally, based on a June 2011 datasheet. The LH351A datasheet is here.

Samsung uses ANSI White chromaticity quadrangles for its tint bins. The 2700K quadrangle is called W0 and is broken down into 4x4 grid of smaller quadrangles W1 to WG, numbered left to right and bottom to top. The 3000K quad is called V0 and is also broken down into 16 subquads called V1 to VG. The 5000K quad is called R0 and is broken into 4 subquads R1 to R4 with R5 and R6 below the subquad and R7 and R8 above it, outside the ANSI quadrant.

The 2700K and 3000K LEDs have a minimum CRI of 80, while the 5000K LED has a minimum CRI of 70. Forward voltage bins are E3 for 2.7-3.0V and H3 for 3.0-3.3V. The maximum flux bins available are K1 for 2700K and 3000K and N1 for 5000K.
