Incandescents have the single advantage of being ultra simple. You plug in an incandescent, the 120V or 230V or 240V goes straight across the tungsten wire and the lamp lights up. But, incandescents are a thing of the past, and should be, if you believe in using energy more efficiently AND SAVING MONEY on your electric bill.
LEDs are quite white, ultra long lasting when appropriately constructed, and use less energy per lumen than the fluorescents, and as far as I know do not have mercury, as do some of the fluorescents. You can buy LED screw-in lamps at Costco now, both the dimmable and non-dimmable kind.
And make sure you don't use non-dimmable in a dimmable circuit. Life is cheaper, but more complicated with LEDs and fluorescents.
