I read that there are only 6 E12 bulbs, and when I looked up E12 bulbs, I read that "the wattage ratings for incandescent E12 bulbs are typically 40W or less. Rather than a focus on providing raw brightness, E12 bulbs are typically used where accent or decorative lighting effects are desired. Wall sconces, lanterns and outdoor fixtures are all common places where E12 lampholders are used." Is it enough light for one room on its own?
