Aphelandra prefer to be sat in medium light with the absence of deep shade. As you'll have to keep the soil relatively moist, the risk of soil mould and over-watering is considerably increased when maintaining too little light.
Once the autumn kicks in, be sure to include an hour or two of direct light per day to get it through the dormancy period, lasting until the following spring. Remember - acute exposure to the sunlight during the spring or summer of more than an hour will negatively affect the plant.
