Standard incandescent Lightbulb replaced by LED Lightbulbs
Standard incandescent Lightbulb should be replaced by LED Lightbulbs due to higher efficiencies of the LED light bulbs.
You should get the warm white type LEDs with 2700 to 3000 Kelvin light temperature , cause they are much better for your eyes.
The current best light output that resembles the Halogen light the most comes from company OSRAM with their IVIOS LED brand.
There look very much like the very warm and sunshine simular light temperature as from Halogen light bulbs but only consume a fraction of power, what the halogen light bulbs consume.
