STARWELL is a professional manufacturer of power supply and charging equipment. Our quality 450-800mA 30W Constant Current LED Driver delivers steady, safe power supply for indoor LED panel lights, downlights and decorative ceiling lamps for residential and commercial lighting projects. Built with stable constant current control technology, it supports a maximum power output of 30W and features standard AC input of 220–240V 50/60Hz to fit European and UK mains grids, with rated input current at 0.15A. It outputs DC voltage within a window of 30–38V and boasts a power factor above 0.8, equipped with a round compact plastic housing for neat fixture embedding.

Starwell factory’s durable 20W Dali Dimming Constant Current LED Driver is specifically designed for high-end commercial and residential lighting systems. It strictly adheres to the DALI-2 standard protocol and can be seamlessly integrated with various DALI controllers and systems to achieve smooth, stepless and precise dimming (typically within the range of 0.1% to 100%). It adopts an efficient constant current output solution to ensure that the connected LED strips or modules maintain stable light output and no flicker at different brightness levels, effectively extending the lifespan of the lamps.
