driver selection

hey guys im working on a new project that's going to be quite expensive :( but i need a good driver for it that will not over heat in 2 seconds

im going two put 4 EZ900 XR-E R2 in a host powered by 3 or 4 26650 or 18650 what ever is best run time ect..........

im wanting to drive them at 1.5A ish any idea on what driver i should use ? nothing to expensive i know they can get up there in price any help would be great thanks

Are you doing the LEDs in series, I assume?

I don't know of anything that would put out 1.5 amp unless you get into the more expensive drivers that are adjustable.

These two, but I do not know a thing about them. Hopefully someone will come in and suggest something.

yes i think ill run them in series if its more than one driver, as for price range id like to spend no more than 10 to 20 bucks just something dependable
