I bet you would be OK with either of those fixtures for shrooms and ricordea.
But if you were going to have some more demanding corals later you might want to think about stronger lighting for a 100.
I am not an expert and now that I am building my third system I am also trying to answer the lighting question all over again. Every time I look for lights I have to start the whole research proses over again.
Hopefully someone smarter than I will chime in.
But its true that you can never go wrong with saving money a little longer and really get what you want. So you do not end up with a grave yard of things that don't do what you need like me
