With a constant current source, even as the voltage changes with temperature the driver keeps the current steady while not over driving the LED and preventing thermal runaway.
The most common LED strips are designed with a group of LEDs in series with a current-limiting resistor in line with them. The manufacturers make sure the resistors are of the right value and in the right position so that the LEDs on the strips will be less prone to the variation of the voltage source as we talked of with the XP-G2.
Since their current is already being regulated, all they need is a constant voltage to power the LED s. You use a constant voltage LED driver only when using an LED or array that has been specified to take a certain voltage.

Constant Voltage LED Drivers Constant current and Constant voltage drivers are both viable options for a power supply for LED light sources, what differs is the way in which they deliver the power.
