We have been using they Hayward LACUS 11030 160 Colorlogic spa lights for a couple of years now. They keep failing under the same circumstances, were they will stop working after 7 - 12 months. The reason we keep using them is because they are the same size and we do not want to enlarge the hole were it is installed in our concrete spa and risk cracking something. 

Is there a better quality spa light (color changing) which is the same size, that you guys would suggest? Maybe even a couple of options? 

We would really appreciate your advice. 

Looking forward to your response.
