The era of incandescent light bulbs starts to be over. During the last years people have come more cautious of the energy efficiency (in Finnish, energiatehokkuus) of every product, especially light bulbs, which have caused other forms of light bulbs to become more popular than traditional incandescent light bulbs.
It has been estimated that incandescent light bulbs will vanish from stores by the end of 2013. Their place will be taken by energy saving light bulbs, which can produce 80 percent more light from the energy they use than incandescent light bulbs.
The development of energy saving light bulbs has been quick. In beginning, they were criticized heavily of their outlook: nowadays the look is not a problem. The old image of an ugly looking energy saving bulb can be easily demolished by visiting the nearest shop selling bulbs: today, they can be done in any shape, from the shape of good old incandescent light bulbs to big balls – just to mention a few.
Some criticism has been put to the fact that the lights come on slowly when energy saving bulbs are used. That is related to the different technology that energy saving lamps bulbs are based on. The quicksilver inside the lamp is used to make ultraviolet light, which is then turned to visible light. As soon as the lamp lights up the light is on, but some energy saving light bulbs reach their full capacity only after a few minutes. That issue is under continuous development, and some newer models use already technology, which speeds up this lightning process.
There have been critical comments of energy light bulbs getting easily broken.
Energy Saving bulbs’ development has the aims of make the average life span of energy saving light bulbs longer, made them faster to light up, and improve their outdoor features. In the future, energy saving bulbs are likely to have the same features than incandescent light bulbs today – and even more.
