LEDs may be the answer but so far I have not seen an acceptable LED replacement lamp for the standard incandescent.
Quantum-dot LEDs will be a great solution. The price is still very high because the industry is just starting and not scaled up yet. But using quantum-dots to change cheap blue LED light to white light is one of the most straight-forward applications of the QD technology and will be one of the first to go commercial.
Also look for quantum-dots to be used first for backlighting cell phone displays, and next for the entire display.
