So I am about to make the jump and buy a strip or two, but first i have a few questions what does the optics do? Also do you think 2 strips will be good on each side of my fixture it's a 36l 16w 18D (Believe thats my 50g breed dimentions) They would be hung roughly 5-8inches above whater and are they dimmable?
Lastly what is the coverage with these?
