I got 10 of those boards
in 3000K but haven't done much with them yet.
The boards and drivers are made by an Italian company TCI:

The seller told me that the boards were custom built for a lighting manufacturer but the product was discontinued and he bought the surplus. He couldn't tell me what type of LEDs they use - all I can tell is that they are 5630 SMDs and that each board is configured as 16 serial sets of 6 leds in parallel to make 96 LEDs in total. There are other boards on the TCI website but nothing the same as these. TCI does have a partnership with Samsung.
The driver looks like it is a TCI superslim driver (

This is a 25W constant current driver that can be set to output 350, 400, 450 or 500ma depending on what the dip switches at one end are set to - I think the dip switch settings should be:
Code:
1 2
350ma
400ma On
450ma On
500ma On On
I am considering connecting 4 or 5 boards in serial or parallel to a larger dimmable driver instead of using the supplied drivers to see how then run at around 700ma each (with a suitable heatsink).
