i am running 8 x 54w giesemann globes over my tank, each with their own reflectors, tank is 1200x800 and 500mm deep, the unit sits approx 15cm above the water line, pic below on new tank, how far can one have it? obviously the higher the less light, is there an optimal hight? might be a stupid Q but something i have been wanting to know
