When you hold the white and blue up next to each other, the white is noticably brighter. The blue has tiny little bubbles through out the epoxy coating too.
I guess I had higher expectations of what I thought the blue would look like.

One of the things I was thinking with the blue was hanging it away from my tent next time I go camping. Hopefully mozzies will be attracted away from my tent, and I will use the amber as the light in the tent to avoid attracting them.

The white does stand out from a distant and when flashing is quite noticable.
