Is a light bulb brighter than the sun?

No, a light bulb is not brighter than the sun. The sun's surface temperature is around 5,500 degrees Celsius (9,932 degrees Fahrenheit) and emits an enormous amount of light and energy, roughly 100,000 times brighter than an average light bulb. While a light bulb can provide illumination in a confined space, its brightness is negligible compared to the vast intensity of sunlight.
