This particular LED has 50K hours of burn time (5.7 years of constant use)..

“Remember: LED lights are directional (like a spotlight). This EcoLED light has a beam angle of 100 degrees, which is equivalent to a wide spotlight. It is not appropriate for use in lamps with lamp shades or other lighting applications where light needs to be emitted in all directions at once. (However, it can be aimed at a wall or ceiling to produce radiant ambient light that radiates through the entire room.) Also note that this EcoLED product produces clean, bright “white” light, not the typical yellowish light produced by incandescent bulbs. Most people agree that our white lights offer far better visibility and clarity than common yellowish light bulbs.”
People like yellowish light for a reason. It's not perceived to be as "harsh". That said, LED lights annoying effects can be partially mitigated by being mixed with other lights.
Don't LEDs still flicker with the cycle too?
Couldn't this be remedied with some kind of reflective surface?

Couldn't the light be covered with a yellow filter, for those people who want warm light?
