LEDs give projects a colorful aesthetics, but it also requires much power if you want a series of LEDs to be powered up. This LED driver would give you sufficient power supply for your LED. What's good in this is you can even have them paralleled in a double-decker fashion to have more as well as power(watts).

This LED driver can output up to 350mA, and 1Watt, enough to power up 10 LEDs. It can also have a wide input range of 5V 

to 35V, to be stepped down into 5V to power up LEDs. It triggers the LEDs off when the signal is HIGH and turns it on when the signal is LOW.

This LED driver also has PWM inputs to control and dim the lights. With this small module, it is sturdy enough to be driving up to 10 LEDs, with constant current output, with low ripple. It also has overload, short circuit, overcurrent protection that makes it more compelling in any power supply within its voltage range.

The connection from your power supply to the LED is as follows: VIN+ and  VIN- is for the input power supply; LED+ and LED-

is for the LED output. It also has 2 pins for the control, PWM and GND. This module doesn't need an external power supply to operate.

It could be used in controlling 2-pin LEDs like the typical ones, as well as LED strips that are controllable only by 

ON or OFF.
