Nothing special about the different Vf range if you are using a constant current driver. It's just matter of picking based on your input voltage and the Vf range. What input were you looking to use?

I was looking at 6.3 to 8.4 as in 2 lipo cells. it is for a rear back light for a bike. I am thinking of non modal version so i can flash the light by interrupting the power.
