“These controls take all the hard work out of lighting the aquarium. Set the 4 periods of adjustment , play with the differing percentige levels to set the levels you the individual require. Throw away the old timer . Give the fish and plants a proper days lighting . Even individual days can be set so some are brighter than others.. Set and forget”
“Fits the vision 180 perfectly . Gives me perfect lighting over the whole day . Very happy with this product . Much sturdier unit than the standard led unit supplied with tank.”
