I was first looking at these last year when the original non-pro version was available. However, they were impossible to get and I didn't really like the white color. I'm glad I waited because not only does the pro version come in black, but they have dedicated white LEDs and each kit comes with 3 extensions (one 12 ft., two 4 ft.) and some very nice weatherproof splices if you need to cut/extend the lights.
We don't have a solid surface under the eaves , so I had to create something. I got some 2" furring strips and painted them and screwed them in under the eaves. That gave a nice straight surface for mounting the lights. We have sort of a complex roof line in the front, so the installation took about 5 days or so for everything (About ~200 ft. worth of lights) including painting/mounting the furring strips.
One important thing I will say about install is make sure you mount these about 2-3 inches from the wall! A lot of the people on Youtube that have videos installing/reviewing these lights install them way too far from the wall, closer to the gutter. This causes you to lose that curved glow that shines down the wall.
The 3M adhesive on each light is ok, but it needs reinforcement IMO. The lights come with some nice screw in clips, but they only come with about 30 of them per lighting kit. This is enough for 1 clip approximately every other light. Not a huge deal, but it would be nice if Govee included enough clips to have one on each side of each light to really secure them. I ended up using zip ties on the side of each light which actually worked even better in my scenario. I also mounted the power supplies/controllers in the garage and ran the cables up and out one of the soffits in the back.
Overall, I'm fairly impressed with everything and the Govee app has a lot of options if you really want to get creative and put time into it.
So I was able to get the outdoor pro line and after some trepidation of going all in and installing it myself As soon as I had a Nice day and a latter and begged the Wife to hold the latter we were up and going and after 3 hrs we had the job done, my neighbors have come by raving how great the lights look, and then they said to bad you have to take them down in the winter and when I tell and show them there permanent lights the surprise is on there faces and now they want the lights too!!
I just love my new Govee Permanent Outdoor Lights Pro. I bought two sets of them to cover nearly the entire perimeter of my house. I just love the flexibility they give me to light certain segments of them for different purposes. They look stunning, and are so well designed! And, I sincerely mean that! Great (no GREAT) product!
