This Small and lightweight UBEC features a High efficiency switch mode design providing better heat dissipation when compared to the linear voltage regulators. The shielded PCB design and output EMF coil makes helps provide a stable and low noise voltage output. This UBEC also features built-in reverse polarity protection.
Specs: Input: 6V-23V (2-5S Lipoly, 2-6S Li-Fe or 5-15S NiXX Battery Pack) Output: 3.3V/3A (Less than 50mV peak to peak voltage @ 2A) Dimension: 22.9mm x 20.3mm x 7.6mm (LxWxH) Weight: 5g (w/o wires) or 7.1g (wires included)

You need a Servo Cable to connect to the Conector on the Picture. Red has to be conected to the Anode, Black to the Cathode of the Diode. But it will give you 3.3 volts to connect diodes in serial. Most Led systems will work with 12 volts. Maybe bether for beginners.
