Driver question?

I’m looking for a LD driver that has mode fuctions. Strobe and high is what I’m interested in. But any/all LD drivers that had the mode fuctions I’d be interested in. If those are not to be had. Was wondering if anybody might know of any LED drivers that might not be to hard on the diode(s). I’m interested in 3-5 amp driver(s) planning on use the n465 in a build. Thanks for your time.
