Hello scholars :GRADE:
I am making a hand held flashlight with three 10w XML L2 LEDs. Using 18650 cells.
I dont want to put them all in serries and make a 12v circuit.
I want to run them as parallel.
I have 2.5A XML 10w drivers with 5 modes.
So I wanted to ask:-
Will it be good if I add 3 separate drivers for all 3 LEDs?
Or, what else can be done?
Thank you 
How many cells and are they series or parallel? With parallel cells you can do the LEDs in parallel and use a single fet driver. With two series cells into three parallel LEDs you need a buck driver. With 3 series cells then possible a specialized linear driver.
