Using the appropriate led controller it is possible to adjust the brightness of the led without any flickering effect. Not all led controllers are capable for led dimming; proper dimming for led lighting (avoiding led colour shift) can only be done by pulse width modulation based controllers. LT-SYSTEM-3600RC is a full colour multifunctional rgb led controller based on PWM technology and designed to control colour changing combinations of LED strip lighting with 4-pin 3-loop cables (common anode). It can be adjusted through manual buttons or matching remote control device. Also this unit can run as a standalone controller or linked with an rgb amplifier which can unlimitedly expand its capabilities.
