Will it still be safe in the rain?
The product that Waterwell installs is designed for the job. It is waterproof, safe, high quality and robust. Unfortunately though, the downside of quality is cost; good quality components cost more money but they will last for years.
When you're getting quotes you'll probably find some companies will offer to install a very inexpensive systems but be warned, it is a false economy. Like most things in life, you get what you pay for and cheap lighting systems will fail and practice, we regularly get asked to upgrade systems, often no more than a year old, that have failed due to the use of inferior components.
