Hi

Im not electronics expert so can someone please assist?

Would these be ok for your garden variety 3W leds? Im looking at some of the amperage and its higher than what a typical LED would need (~900MA). Does it have to be exactly the same amperage for the LED and the driver?

Waterproof 12V Power Supply - IP67 rated LED driver for LED Lights 15/30/60/100/150 Watt

or this meanwell one:

LPC-35-700 Meanwell LED Driver 9-42V at 1.4A IP67 - SwitchMode PowerSupply - Electronic Components - Rabtron Electronics

As long as the voltage is in range and you have amps equal or more than is required it should be fine.

If you connect a 12 V 100 mA device to a 12 V 1 amp power supply, the device will draw 100 mA.

cunsumption requird is current consumed
 
Ok so does it mean if i have a 700mA led and a 5000mA driver, it should work? The LED will only draw what is required?
 
My 2c,

LEDS can handle higher voltages, BUT to much current and they will burn.

I tried this experiment and popped 20 LEDS
