Comparison of Light Bulbs

All of us are aware of the fact that when we switch on a light bulb some heat is produced which is enough to burn skin or paper. However, the heat produced by bulbs varies according to the type of bulb and there’s a huge variety of bulbs available in the market. Comparison of bulbs can be taken as a Science Project as it’s easy to perform as well as doesn’t involve any high costs. ¬†Generally, there are two basic types of light bulbs, the incandescent and fluorescent and both of them are easily available in the market easily.

Your experiment can possibly make incandescent bulbs users to go for the fluorescent light bulbs when demonstrated in terms of energy saving. Make sure you have the following before conducting the experiment.

Things Required:
-Two Bulbs: One incandescent and one fluorescent bulb producing same lumens
– Lamp
– Thermometer

Instructions

  • 1

    Getting Started with Fluorescent Bulb

    Place a fluorescent bulb in the lamp and then switch on. Now observe the light carefully produced by this bulb which should include the color as well as the heat.

    Note Down the Temperature

    Bring a thermometer and hold it about 6 inches away from the lamp for about one minute or so. Take the temperature and note it down on a writing pad.

    The Incandescent Bulb

    After that turn off the lamp and allow the bulb to cool. Now replace the fluorescent bulb with an incandescent bulb in the lamp and switch it on.

    Light and heat produced

    Observe the light and heat produced and measure the temperature by holding thermometer about 6 inches away from the lamp. Have the temperature noted as before.

    Making Comparison

    As you compare the two readings, you will notice that the temperature of incandescent bulb was higher than that of the fluorescent bulb. Hence, the bulb that produces a lesser amount of heat is good to use.
