Incandescent bulbs actually put out a very yellow light compared to natural (sun) light. For the most part our eyes adjust to it and we don't notice it much. Look at a photo taken indoors, at night, with no flash and you'll see just how yellow it is.
White LEDs produce a more white light, probably a lot closer to natural light than an incandescent. They aren't perfect, for sure, as many do have a bluish tint to them.
Finally, are you looking for a recommendation for a raw LED or an LED flashlight?
