Ok so I recently aquired 16 RB Cree XPG LEDs and 8 Cree XRE LEDs, along with some 500ma buckpuck drivers. (thanks Stephen) So i would really like to have the ability to dim my LEDs to transition smoother than 0% to 100% power. I was looking on some imput as to what kind of driver to get and why. As far as I know mainly people use the Mean Well ELN-60-48D dimmable driver or the Buckpuck dimmable drivers. First question is with the buckpucks what is the diffrence between 500ma and 1000ma? Is it that the 1000ma will burn 2x as bright as the 100ma? Next question is to my understanding the Mean Well drivers require a controller of some sort such as a Reef Keeper Lite (correct?) but do the buckpucks?
