Adam, as with many houseplants, Epipremnum ('pothos'...not really actually a pothos at all) will tolerate a lot more light than you think. Its normal growth habit in the wild really is not to drape and hang and grow downward, its to climb and reach as much available light as possible. Many plants that are used commonly as houseplants today were selected for that purpose (growing indoors) because they come mainly from the understory layer of the rainforest, where the light is dim (this layer gets only about 5-8% sunlight). The vining ones climb because they are trying to reach the canopy layer, at a level of about 100 feet, where there is a lot more sunlight, and as they climb, their leaves get bigger and bigger to capture more of that available sunlight. Before deforestation, there was almost no light that penetrated to the forest floor. So most of the plants that evolved there developed larger leaves and taller stature to grow up and be able to capture available light in the understory. Plants like heliconias, the natural species of Musa (banana), small trees and saplings, small shrubby plants, palms. The understory layer contains most of the houseplants like ferns, philodendrons and other aroids, maranta and calathea, passiflora, vining philodendrons, palm trees, and the broadleaf tropicals with brightly colored flowers to attract pollinators (heliconias, gingers) that start on th floor.
The canopy layer (which starts at about 100 ft up in the air) gets about 80% of the sun an this is where all vines are trying to go. Many plants in the canopy never start on the floor but are brought to the canopy as seeds by animals who drop them in leaf litter on trees, where they grow as epiphytes in the higher light. (orchids, bromeliads, moss,epiphytic jungle cacti,,epiphytic aroids like bird nest anthurium, and even some Monsteras and other vining philodendrons)
