Does a light bulb use more energy when in the dark?

For most light bulbs, they consume equal amounts of energy regardless of bright or dark environments. This is because a light bulb is simply lit up by a power source, and is unable to control brightness, producing the same amount of light. That is why most people say we should not waste energy by switching on a light bulb in the day.

What will happen on lighting a bulb during day?

A normal light bulb will light up in exactly the same way, using exactly the same amount of power and giving exactly the same amount of light whenever you light it. The only difference is, if you light the bulb in a dark place, or at night, it will brighten the dark area. If you light the bulb in an already bright place, or in daylight, it won't change the ambient brightness: it'll just waste power.
