First, sometimes compact fluorescent bulbs are defective long before reaching the 10.000 hours promised. Second, after half of their lifespan, this type of bulb starts to provide a little less light. Then people sometime change them before they have reached 10.000 hours. Thirdly, the incandescent bulbs provide heat which, in winter, heats the room. This heat is not as negligible as it seems. Indeed, the replacement of the bulbs will require a little more heating. If one compensates by electrical heating, the real economy provided by the replacement of 10 bulbs becomes as little as 2.50 dollars per year! Outch! The initial replacement of 10 bulbs will cost you 40 $ immediately!!
That hurts your wallet! In addition, compact fluorescent bulbs contain a considerable amount of toxic products and dangerous. At such point, which it is recommended to leave the room and to ventilate it before cleaning the mess... It is thus important to educate children to warn us in the event of an accident. And despite everything, I am not ready to put compact fluorescent bulbs in my son's gaming room before having to replace the suspended luminaire that does not protect the bulb. |
