LED Lightechs Power Supplies IP66 are for use indoor and outdoor and are available from 30 watts to 350watts in different voltages 12VDC or 24VDC. If used for an RGB light the controller CT308RF along with a power supply must be used or the CTR RGB BOX with built in driver depending on the wattage and amps of the lights.
To get the amps of a light divide the wattage of unit by the voltage for example:
36watts divided by 220volts =.16amps
36watts divided by 24volt    =1.5amps
36 watts divided by 12volts  =3amps
