Just what I was looking for.i always decorate my Christmas tree with c7 size lights but the heat was to much for the tree .I went with the led bulbs which stay cool all the time and look great I also added the led twinkle string to the tree looks great.
I finally broke down and got some outside Christmas light. I saw these and have had excellent history with Monoprice and bought (3) 50- strands. I installed them this last weekend. They look great. I only installed two since I ran out of space. They look great and are pretty bright.
As you well know the proof is in the pudding. I have had these lights a couple of weeks and so far not a hitch. I am looking forward to many years of performance. I have them on my back deck partially exposed to the elements in Alabama and as I said so far so good.
Nothing special as far as I can tell. Not sure what makes them "commercial". They work fine, look good. Average brightness. There are lots on my street that are brighter. I don't think they were much cheaper than local big box stores, but hey, they are up and that project is "done".
