There are so many people having difficulty changing the bulbs. The fact is, there are some reasons that make it hard for those people to do it such as a vague fear of it, your physical conditions, and or its knottiness. So, now I would like to introduce this new fluorescent light that features its foldable structure. It solves not only those problems above but those caused by from carring and or keeping to disposing of it.
