Option 1 looks the strongest of the 2 (looking at the lux). But it still sounds like a low light setup depending on the volume of your tank?
It is a 20g high, I wasn't sure how to calculate if it is low or medium light setup so to be safe I just said low-medium. Also what is the lux?

Uhm, not planting any trees, but I am doing plants. Some plants I might do are Jungle Val (maybe other val) Various Anubias, Various Crypts, Java Fern, Amazon Sword, Water Sprite, Hornwort, maybe some duckweed or salvinia as a floater. Also 20g high, I think it is 24 inches long, 18 inches tall, and 12 inches wide but I forgot the dimensions lol.
With the size of your tank. The two lights above are too weak
But if you buy then I would recommend model 1
Cause you plant a tree with a different color such as : red, pink bla bla . Lights 1 will better assist in displaying the colors of the tree

Lol I don't know if your just trolling or something but I am NOT planting trees. Idk if you mean plants. Also I am doing a low light setup so the lights don't have to be too bright.

Tropica suggest 10-20 lumens per litre for low light plants. So you'd want 760 lumens minimum. But you want a decent PAR especially for a taller tank otherwise not much light gets to the bottom. Those listing have limited info from what I can see to compare them properly but I remember from my research before I think the classic one seemed stronger out of the 2. Not sure what wavelength are given off by the Sky version either. NICREW do have a plant specific one too. Lux is like the intensity. I am not an expert on all the specifics though sorry



EDIT:
I just found the one I liked for my taller tank. Not sure if it'll be abit strong for yours if you want to stick to low lighting: https://www.amazon.co.uk/dp/B08CXR8...&ref_=ox_sc_saved_image_1&smid=A1SCNCT8HBI2E6

Sorry, it's on the UK site! It was actually another member here that kindly recommended this brand to me as a cheaper alternative to the bigger brands.

Thanks! Even though you said your not an expert that's still some helpful info.
