Question about Juwel Aquarium HeliaLux Spectrum

I have the Rio 350 and two HeliaLux 1200. The beam angle is really bad so that with one luminaire the upper foreground and background remain dark. The lumens per litre should be less than 25 for the 450 and one luminaire. That is too little for light-hungry plants. For cichlids it is optimal.

1 It's enough if you have the AQ with the straight glass. You can then replace the old centre piece with the Helialux👍🏻.
