The hlg-240-20 has a voltage range of 10-20V. These strips can pull up to 22.6V, depending on their temperature. You won't realize full power and may experience other weird things with a 20V limit. The HLG-240h-24b is likely a better choice, as it runs 12-24V, covering the entire range of the strips...
