hi

this has been advertised as a it can driver 3x 3W LED's, however most LED's need 700mA so can this work as its 600mA? if it works can 3 LED's be set up in series or will it need additional resistance? thanks

DRIVER
* Input voltage: AC/DC 12V
* Output voltage: DC 3V-12V
* Output power: 3W-9W
* Output current: about 600mA±5%
* Soft start
* Over-voltage protection (OVP)
* Short Circuit Protection (SCP)
* Overload power protection (OPP)
* Overload current protection (OCP)
* RED wire: Output Positive
* White wire: Output Negative
* Can support 1-3 pieces 3W diodes

LED (x3 in series)

Forward Voltage: 2.4-2.8V
Forward Current: 700mA

A 700mA LED can always be used at 600mA, but not vice versa. 4 of your LEDs in series add up to 7.2V...8.4V. This driver is a good match for this setup. No resistor will be required as the driver is a current source that adjusts the voltage such that the current is regulated to 600mA.
