I’ve used 110 volt lights to decorate my sailboat top of mast for years and the 110 volts I was lucky for them to last 3 months . I switched to 12 volt and they last almost a year before breaking down .
You have to realize the lights are operated 50 feet in the air exposed to sunn, wind and salt air .
Since climbing the mast is not an easy job it stands to reason I’d want to purchase lights that last as long as possible, fewer trips up the mast .
I’ve constructed a 7’ diameter peace sign that is illuminated every day . So far these lights are so much more durable and i recommend these lights for your indoor or outdoor use . Good product!
