5. Conclusion

5. Conclusions
5.1 Key findings

In conclusion, we have found out that LED bulbs have the lowest UV emissions and are the least harmful to human skin.
5.2Explanation of key findings

The value that we got in the cupboard, a control variable was 3.00. The closest value was that of the LED bulb with a value of 0.0229. This means that LED bulbs are the better bulbs to use as they are close to having nothing. The second highest was that of the tungsten bulb. It had a value of 0.0217 and the fluorescent being the lowest with a value of 0.00107.

5.3 Evaluation of Hypothesis

In our hypothesis, we thought that LED bulbs had the lowest UV emissions, the results from the experiment had shown us to be wrong as the LED bulbs were the most dangerous bulbs to use. Thus we have predicted a wrong hypothesis. Our hypothesis was actually based on the fact that we use them in our daily household everyday with not too many ill effects and the fact that it is able to direct light and seemingly improve light intensity with the same average amount of UV, which was in fact wrong.

5.4 Practical Applications


With the data that we get, we can inform the public whether the bulb they are using is efficient or  whether it is safe. This was our aim for the experiment. Overall our experiment can help consumers in their choices for the healthier bulb. This is to make sure that the consumers are safe from the harm of UV radiation even in the comforts of their home and are having financial safety while buying bulbs. UV radiation is emitted from the light bulbs, the very same thing which sunlight consists of, except that the UV is more concentrated.


5.5 Areas for further study

One area of further study would be the study of the effect of bulbs with higher UV radiation on live human tissue. The effects on human skin may be different with that of the effects on human muscle tissue, organs or even animals. Should zoo’s use artificial bulbs or the natural sunlight for the animals. The fur on animals can also have an effect. These questions are some areas for further study that our group can work on given more resources such as time
