I purchased afew Lake Lites about a year ago, more of an experiment to see if they were going to work for my application. They have exceeded my expectations even on the longest, coldest, darkest winter days and nights in north central Iowa (-30°F) the lights are as bright at dawn as they are at sunset when they first come on. I’ve had them over a year and I am ordering a few more to complete my project. The people were very helpful and treated me right. The product and company as of now are Definitely five stars in my book.
