Explain the narrator's desire for light in his hiding place in the basement

The narrator takes his revenge on society in silent, unsuspecting ways, such as stealing electricity from a power company by wiring his room full of light bulbs. He resolves to cover even the floor of his underground hole with bulbs, out of spite and a desire to hold and control as much light as possible. Light is truth and vice versa, he claims. In this way, his hibernation will be warm and well lit and he will continue to be alive.
