Default Overdriving/underdriving LEDs
What happens if I run too many LEDs on a constant current driver? Or too few?

I have lots of 5 watt LEDs, and drivers that are rated to run 7 pairs (7 parallel branches of two diodes wired in series). Voltage output of the driver is 27-36 vDC, current is 2100 mA. Each diode is rated for 15-17.5 v, 300 mA.

I need to set up two light fixtures at opposite ends of a room, and 7 pairs doesn't split nicely between them. What would happen if I put 8 pairs on this driver? Or if I set up two drivers, each with less than 7 pairs?
