My rh% with one dehumidifier running is about 55/56% on a good day but 59/62% is nearer the average, with a 2nd dehumidifier running outside the tent I can get 50/53% but they costs almost the same as the lights to run so don't like running the two.
Dehumidifiers create a bit of heat which is a bonus to me as the extra heat cycles the fan more helping keep down humidity without sacrificing heat.
At night a dehumidifier is more useful than a heater (in my situation) as it gives of heat while keeping down humidity, the equivalent wattage heater keeps my tent at the same temperature +/- 0.1c but at 75/80% rh
It's humid as where I live.
