hello
i read on 3w star led data sheet that on If-700mA the min Vf is 3.4v and the max Vf is 4.9V.is it mean that i can directly(direct drive)the led with voltage source of 3.4v and increase it till it get 4.9V without any issue?
how much does it affect the bright of the led and the current?
thank in advance
