For reference I originally had 18 of these lights in my garage/workshop. I had them running 2 sets of 8 on 2 separate switches, and a set of 2 on 1 switch. The switches are plugged into an outlet in the garage.I have been using them for around 6 weeks at this point. I use them daily for several hours.The first thing to know is that the lights themselves exceeded my expectations for the brightness and functionality. For what I purchased the lights to do, my opinion is that expectations are beyond what I was hoping.Installation: I installed the lights running front to back in 4 lines of 4 each. I also installed 2 above one of my workbenches and attached them to the underside of the shelf on the workbench. I used the included hardware other than changing the mounting screws out for longer screws so they would be more secure. I was able to mount all the lights into the cross beams running in the ceiling of the garage so that I would not have to worry about anchor issues. If I were going to use anchors, I would not have used the supplied anchors. I would recommend upgrading to self-drilling drywall anchors. There are a plethora to choose from on Amazon but just for reference, this is what I am referencing:https://www.amazon.com/gp/product/B07F2WMCP2/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1Here are some little hints for installation made easier if you are installing the lights end to end as I did using the included 1 inch union.• I lined up one end to the other using a simple nail and string to help me keep the line straight. (a nail at each end and the string from end to end.) However, I highly recommend you install your first light then attach and hold the second light in place, mark the location, and install the second light and so on until you are finished with that row. On my first string of 4 I originally marked the brackets off along the string and installed both brackets for all 4 lights. Big mistake as the slightest amount off caused aggravation. Note that if you are using the included longer union cord, then this will not be an issue.The only reason I did not give these lights 5 stars. ***The switches. The switches are cheap. I mean really cheap.*** Note the included pictures of failed switches where the rocker melted. One switch is melted to where it would not move. The other switch is melted up and will no longer touch the contact, thus it is just loose. You are basically rolling the dice on the end result of the malfunction. After I installed the lights, within a week, I noticed that one of the switches was making a crackling noise and was hot to touch. I watched them all closely after this and never left the lights on without being in the garage. A day later the switch failed. I had extra so replaced it and just wrote it off to 1 bad switch in the batch. Less than a week later, same thing. Ugh…..So I wrote to Barrina via email and explained. No response so I went through amazon messaging and finally got a response. They agreed to replace the 2 switches. I got those switches in the mail. However, by the time I received them a third switch had failed. However, the replacement switches are EXACTLY the same as the originals.The only string of lights I trust at this point to not cause these switches to fail are the ones with just 2 lights on the string. I have not had them fail on that string. You may have better luck having 4 lights on the switch, but I do not desire to have 5 separate switches for the garage lighting varying in length from 15 to 30 ft depending on where I choose to plug them in. My solution was to purchase higher quality switches and just replace the cheap, and in my opinion, useless, switches with the higher quality switches. This gives me the ability to now link 16 lights on one switch and also have the peace of mind that the switch will not burn up and cause a fire if I am not in the garage when the lights are on. Here is a link to the switches I purchased from Amazon. They are installed and functioning like a champ. I love that I now have all the lights on one switch!!!! They were only about 13.00 for 10 switches so not that big of a deal. But still adds to the cost if you are comparing based on price.https://www.amazon.com/gp/product/B07XPN8PL8/ref=ppx_yo_dt_b_asin_title_o02_s02?ie=UTF8&psc=1To summarize:• The lights are amazing. I highly recommend them, even with the given switch problem.• They function exactly as described, if not better.• Installation is simple. Just remember what I mentioned in my tip to keep them aligned in a long string.• Switches are cheap and I would not put more then 2 lights on them at a time. Thus, you may want to include the cost of purchasing higher quality switches into your budget, if that is an issue. Click on the included link above for the switches I purchased.
