Current rated LED’s require a constant current such as 350mA or 700mA, these LED products will also require a forward voltage that is specific for the particular LED being used in the product. A current rated LED needs to be specified with these two factors taken into consideration i.e. 4 x LED’s rated at 700mA with a voltage of 3.2vDC each will require a driver that produces 700mA with a minimum voltage of 12.8v. Current LED’s also need to be wired in SERIES.
Voltage rated LED’s require a constant voltage such as 24vDC, these LED products will also consume a power (wattage) that is specific for the particular LED product being used. A voltage rated LED can be specified much the same as regular low voltage products i.e. having the required voltage (24vDC) and having a wattage output suitable to the amount of wattage consumption. Voltage rated LED’s also need to be wired in PARALLEL.
