Samsung
Samsung is a Korean electronics company that also makes LEDs. Their main LED for flashlights is the LH351 series which is very similar to the Cree XP series. 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.
LH351A
The previous "3535" 3.5mm x 3.5mm model became the LH351A, retaining 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.
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.

LH351B
The LH351B has the smallest emitter area of the three current models. This will give it the most throw in typical flashlight optics, but the least output and lowest maximum current. 90 CRI is listed in the datasheet for 5000K and below but only appears to be available for purchase in warmer tints as of August 2018. Flux bins listed are +/- 7%.

| N3 | 150 | 270 | 359 | 489 |
LH351C
The LH351C has an emitter area between the B ad D models. Flux bins ending in F cover an unusually large +/- 17% range. Sub-bins ending in B cover a smaller range, but when the emitters are listed for sale, the larger bins are the only information available as of August 2018.
CRI of 70, 80, and 90 is listed for up to 5000K. Initial reports as of August 2018 indicate these have a noticeable amount of green off-tint in 5000K, 90 CRI.
