That would depend on the type of light, the wattage, the shape of the pool and the size of the pool.
I didn't know that there were swimming metal walls.
first of all, you will have to drain the pool too put the lights in. then put them on the walls of the pool a yard or two away from each other. do realize, lights are high maintenance. be sure you know all of the pros and cons of pool lights before going to the hard ship of actually getting them.
The Home Depot would be a great place to purchase deck lights. They have all different varieties there. Amazon wouldn't be a bad place, either, but you don't really know the condition of the lights.
Focal Point I know where you got it from lol
Place third, as far as I know. That is for competitions/swim meets but I want to know what you need to do to pass this level in swimming/lifesaver training? You can also get one in surf (nippers)
The Shetland Isles, or Shetland as it is know there, is a great place to see the Northern Lights, especially on clear frosty nights. Even better might be the northern ends of Norway or Finland.
The question is incomplete....
Erm, if you have a vagina you have vaginal walls. The walls are the inside of the vagina (the walls of the tunnel, if that doesn't sound too gross).

It is not really possible to tell that Swimming caused this condition. It is not likely to be caused by swimming in salt water. Fresh Water however (not chlorinated as in a public bath) might expose you to various bacteria that ultimately might cause an ear infection or other infectuary problems. Statistics can be used in order to determine the likelihood of an infectious disease spreading from a particular place. If a doctor get many people with similar conditions after swimming in the same place/water, then this increases the likelihood of this.
