from Good, could be great.This is a decent kit that with a little refining could be really great. It does not include a power supply, only the current driver and comes with NO DIRECTIONS. Furthermore there was thermal grease included tho I was told it was. With an LED circuit simulator I was able to determine that 12 VDC would drive this array without the need for a high power resistor however the data sheet for the driver gives a vague 9-36 volts which is the capacity of the driver not necessarily the emitters included in the kit. I also have a 24V power supply that I may try, but I think its going to be too much for only 3 emitters (watch for the flash and blue smoke)... Another minor annoyance is the lack of mounting consideration for the current driver. The heatsink is only drilled out for the LED stars and with the terminal blocks soldered to the board the driver would short out unless it was insulated from the heatsink with standoffs.With a power supply, a simple schematic, and mounting consideration for the driver this would be a GREAT kit. The price is nice, and it is simple to put together (if you know how the circuit goes). I built the whole thing in 10 minutes or so. Some optics or a reflector would also make a really nice addition!
