It is relatively inexpensive. It is small and light. It is waterproof. The wiring not too thin. It comes with a connector on the dc side.
It does not deliver rated current of 680mA.
It is not uncommon for these drivers to output a little less current than what they have been rated or advertised as sourcing. This one falls well short of delivering the advertised output current. It produces only 540mA. It is not 680mA.
The DX listing for this product shows "Waterproof 680mA 3W Power Constant Current Source LED Driver ".
The label on the driver has no output current shown, only "Output 1x3w"
Came here expecting this driver to be suitable for power testing single 3w leds at 680mA. The driver only delivered 540mA into a single 3w led. It was tested with several different single leds: 2.5v red 660nm 3w leds, 3.5v blue 450nm 3w leds, and 3.7v warm white 3w leds. Multimeter showed each one receiving only 540mA.
