Nothing, as far as I am concerned. That is what all the LED light bulbs on the market are currently doing. The price has come down substantially in the last 2 years. I am replacing all my bulbs as they build out with LEDs.
Yup, prices have become quite palatable: still high, but between longevity (1 LED ~= 10 incandescent) and eliminating replacement hassle (obviate 9 climb-on-something replacements), and that the color issue is resolved to my satisfaction, they're preferable.
Only issue now is consistency in group replacements. While I'm replacing independent bulbs as they burn out, things like a vanity with 12 bulbs means dropping some $150 at once to replace all the bulbs so they will all be exactly the same model. Styling & performance is still changing rapidly enough that occasional replacement of a burnout in a group will result in inconsistent bulbs, looking sloppy.
Your vanity is probably specked for something similar to 30 or 40 watt bulbs. You could replace with half as many bulbs (leaving old dead bulbs in place or using some other socket filler) that produce equivalent light to reduce the costs.
