When you are selecting an LED for color, somewhere around 2700 degrees is the color temperature of an incandescent. The higher the color temperature, the more "blue' it will appear.
If you are changing out incandescents for LEDs, using the same socket, hang on to the old bulbs. Should you have a lightning strike or even a near strike, you are likely to lose the LEDs. This goes for lights inside the cabin as well as any attached to your mast.
