A few things to consider:
White LED bulbs come in various colors ranging from reddish golden to a bright white resembling sunlight. It's called color temperature. The higher the number, the closer to sunlight (around 5500° K)
Also, some LEDs are prone to strobing, especially the cheaper ones. This is largely due to voltage being dropped to the 5 to 12 volts the LED needs and also the cycling of AC power. The strobing is usually not visible to the naked eye as your visual center compensates, but it will give you eye strain.
