Hello Ukaps I have a general question regarding recommended light amounts. Left, right and center i see people recommending lights like Twinstar but at the same time I see some of the bigger YouTubers using, ADAs Solar RGB, ONF, Kessil. These have insane wattages and lumen. Par rating is often not discussed, but they are all for planted aquariums obviously. Twinstar 600EA is 31W 2400 lm, Twinstar 600SA is 45W 3200 lm ONF 60 cm is 70W 4400 lm Solar RGB is 130W 3000-3500lm What, how, why? (lm/w fluctuates and do you really need 4400 lm on a 60 cm tank) I am sorry for the vague question. Personally, I have a 50L Scaper's Tank with a Chichiro A-series Plus 400. It is on the second lowest setting. (On full whack, I think i could signal London from Copenhagen). Optional part: If possible I would like to change my Chichiro at some point. It is an Aquarium in an occupied room (dinning/living room). So the light is a bit cold and the finish of the lamp itself is not perfect. A Twinstar 450 E looks more polished and less Kelvin. Will it not be enough or too much. I have no idea at this point. I have a heavily planted tank (or it will be soon) of Easy-Medium plants.
