Put up 15meters of addressable 12v RGB lighting on the front of my house, which accounts for an approx 18amp load and it works great. This supply even has a small voltage adjust dial on it in case the voltage is a bit lower/higher than needed. One tip though, be VERY careful adjusting as even a 1/4 turn increased my voltage up to 14.2v. Overall, I'm very impressed with the quality of the unit and have no complaints at all. My only other comments that has also been mentioned by other users, the fan isn't exactly quiet on this unit. So keep that in mind for your usage.
