“This light is ideal if you have an aquarium with a hood .i have had rimless tanks befor and lost fish that have jumped ,i know you can get screen mesh tops but i find these ugly and prefer rimmed tanks.
these led tubes are ideal for tanks 60cm wide and above ,i would go with 1 x cool white and 2 x sea blue if you like that blue spectrum for your tank, there are no fixings with this light but i used 18mm plumbing pipe clips superglued to the underside of my hood , overall great lights for the price.”
