I am going to purchase a ADA 180P aquarium. Its 180cm x 60 cm x 60 cm. It will be a heavily planted freshwater tank in Amano style.
Lighting will have to hang about 16 inches above the water surface. Which of your products would be most appropriate to light that? What would the cost of the fixture(s) and how would you compare the output etc (performance) to the other option i have in mind, which is 4x Marineland LED Aquatic Plant Lighting systems which are 36 inches long each (would arrange them 2 across and 2 wide).
