@Growlem can you link the datasheet for your leds?
What you need to know is this:
Led: The amps and voltage it needs (one affects the other so check the graph for accurate numbers)
driver: (constant current) amps and voltage it delivers
The amps (current) is the strength of the power and the voltage is how much it can deliver. So you can regulate the strength of the led by the amps and the voltage is how many leds you can run on a single driver.
If the leds can run on a current between 350-1000mA , you can then decide which driver to use. In this example 700mA is somewhere in the middle and should be good to go. Then you'll check how much voltage a single led draws at 700mA (looking at the graph in the datasheet). The lpc-35-700 delivers 9-48v, so if an led draws 5v @ 700mA you can fit 9 leds in that amount of volts (5v x 9 = 45v). (It is recommended to leave a couple of volts to spare).
So, in this example the values should be like this:
Led: 350-1000mA and check graph for voltage (ex. 5v @ 700mA)
driver: 700mA (constant strength) 9-48v (how much power)
at 700mA your leds need 5v each, so if the driver delivers maximum 48v it can supply power to 9 leds (5v x 9 = 45v which leaves 3 volts headroom). Forget about constant voltage drivers.
