Lighting options 150

[Fishnben]

Hi. I'm currently looking into the best option for a 5x2x2 tank that will run CO2 and moderate difficult plants.
My budget allows for either 1x chihiros wrgb 2 120cm or 2x chihiros wrgb 2 60cm.

The lights will be suspended.

Which of these 2 options will be best in terms of best light coverage and what height should they be suspended.

2 sets 60cm are better than 1 set 120cm considering the lumens.
Recommend 15-30cm from light to water surface.
But for a 5x2x2 inch tank with CO2 and moderate difficult plants, WRGB II model is not ideal, WRGB II Pro model is suitable.
