Constant Voltage (CV) is designed to maintain a fixed voltage level during operation regardless of "current" conditions. Similar to how a battery or generator works. LED Strip Light , MR16 and G4 Lamps are examples of a Constant Voltage load. If your lamp has a fixed voltage input e.g. 12V then it is likely to be compatible with a CV driver.
Constant Current (CC) is an operation mode that maintains a fixed current flow through an LED array, the supply voltage will change depending on operating conditions. A domestic style LED Down Light, Commercial LED High Bay and Panel Lights are common examples that use CC drivers.
