Incandescent and halogen light bulbs use more energy than compact fluorescent lights and LED lights.
Fluorescent lamps with magnetic ballasts use more energy than fluorescent lamps with electronic ballasts.
A light bulb uses electrical energy, and produces light, as well as heat.
No. The incandescent bulb uses electrical energy and the light stick uses chemical energy.
No.it uses energy sources (electrical energy to light up
It makes thermal energy (the heat), radiant energy (what we see), which is in essence more or less the same manifestation.

When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
A light bulb uses electrical energy, and produces light, as well as heat.
No. The incandescent bulb uses electrical energy and the light stick uses chemical energy.
The job of a light bulb is to convert electrical energy into visible light energy. (Not ALL of the electrical energy a bulb uses is converted to light energy. Their efficiency is quite low. An incandescent light bulb is more efficient as a heater than as a source of visible light. Fortunately, our eyes are very sensitive.)
Uses more energy and power.
Uses more energy and power.
A light bulb uses energy. It uses electricity.
More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
The power rating for a light bulb (like "40 W") tells how much electrical power the light bulb uses. All of the power used by the bulb is either converted into light or heat. In an incandescent bulb, most of the energy becomes heat. In a fluorescent bulb, more of it becomes light.
It uses less energy to produce the same amount of illumination as a standard light bulb
