There is a tendency to replace all previous bulbs (including halogen bulbs) with LEDs. This is acclaimed as a major contribution to energy saving. However, one should consider:
Lighting is only a minor source of electricity consumption in a household – washing machines – electric stoves etc. are much more energy-consuming
Colors are distorted by LEDs. All museums and art galleries have halogen bulbs, for this reason
LED lamps are much less efficient for reading, if you have eye problems
There are various concerns about LED bulbs
