Yes, you can use the light bulb to shine up a flag pole.
You would need to check your pool light and its manufacturer to see if this or any LED bulb would be sufficient.
A light bulb that produces light perceived as yellowish white will have a color temperature of around 2700K. As the color temperature increases to 3000K - 3500K, the color of the light appears less yellow and more white. When the color temperature is 5000K or higher the light produced appears bluish white.
I believe these are designed for 110 volt use only
