A bright light bulb typically uses around 60-100 watts of power. LED bulbs are more energy-efficient and can provide the same brightness using as little as 10-20 watts.
The remaining 92 watts of energy is dissipated as heat, which is why incandescent light bulbs are not energy efficient. This heat is emitted from the bulb and contributes to the overall room temperature.
The power of a light bulb is typically measured in watts and indicates how much energy the bulb consumes. A higher wattage bulb will produce more light but also consume more energy. LED bulbs are more energy-efficient and have lower power consumption compared to traditional incandescent bulbs.
Energy efficient light bulb saves half of energy consumed by a regular bulb, although it has a lower range light compare to the high energy consumer bulbs.
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
A 150 watt light bulb consumes 150 watts of energy per hour when it is turned on.
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.
The watts because if you put a bulb that is in to much higher wattage than the one that you are chagning then it can cause too many problems and you can have a big piwer outage in you home

40W on a light bulb indicates that the bulb consumes 40 watts of power. This measurement refers to the amount of energy the bulb consumes to produce light. In general, higher wattage bulbs produce more light but also consume more energy.
there are 100 joules in an energy efficient light bulb 75 joules go towards the light and 25 joules go towards the heat
