I have put 2 Colorlogic lights in my pool. One lasted 3 months and the other lasted one summer. I will not put another one in. What is the BEST light I can put in my pool? I really don't care about all the colors that the Colorlogic had, but I do like a blue light. I had another pool 30 years ago and the light just had a simple plastic lens you snapped over the light. Can you buy a light that has a bulb so if it goes out you can just change the bulb? I just want a good light that will last for years?
