The old-style incandescent light bulbs are being phased out. Many countries today already banned the use of those type of light bulbs, in particular those high wattage types. The reason for the ban of incandescent light bulbs is that that they are very ineffective. In relation to their rather high energy costs they produce not much light and a lot of the energy used for those lights is actually being converted into heat rather than light.
Today, people in many countries are switching to more efficient types of lightning fixtures such as halogen lightning or LED lights. Those types of lights are a lot more energy-efficient which means that they can significantly help to cut down on energy costs when it comes to the illumination of homes or commercial structures.
LED lights have come a long ways now which means that they are a lot brighter and actually usable as replacements for conventional lights. Today, those modern and cost-saving lights are offered was everywhere.
One issue for many consumers that intend to buy energy-efficient lightning fixes may still be the higher price as compared to the old style light bulbs.
However, since modern LED lights or halogen lights will usually have a much longer life span, in addition to the cost savings, those lights will ultimately pay for themselves after several months. This should always be considered even when the initial purchase price those lights at first seems to be high.
