Update: February 2022: I’ve had to replace 5 of my LED controller boxes since I installed them. Including one that was installed January of last year. I have not had a single LED light fail. It has only been the Controller Junction Box. One of these days when I have some time, I would like to open one up and see if it’s just a bad solder connection. One of the boxes was going out and coming back on as people would walk on the floor above. I did not change my star rating for this update. I still feel they are a good value. But I’m still concerned about the longevity of junction boxes, which is also the hardest part to replace ;)August 2020: I recently purchased a house and remodeled the downstairs, using these lights primarily. I also added these lights to my 1970’s style living room that did not previously have overhead lights. These are nice and bright and super simple to install.I first added the lights to the living room, which at the first time of purchase I did not originally plan on doing. So that was the first 6 lights used, this was around the end of may 2020. We are super happy with how they turned out. But this meant I was inevitably going to buy more lights for my remodel.As the remodel went along and lights were installed around July 2020; I was running out of lights so I ordered the same product from the same seller to make sure we would have a nice transition and uniformity through the unit. I was now installing the last four lights from the original box, this is when things went sideways. I had a Dead On Arrival light. After doing to testing (plugging in the led to a different box and checking and re checking wiring) I figured out it was the junction box.Side note: The junction boxes are very nice and compact, unfortunately, also very small if you are wiring more than one together.Installation: The lights are easy to assemble. You pop out one of the breakaways and install a wire holder (sold separately) then it’s just a matter of stripping the wires and connecting them together using the wire nuts provided. After this is complete, snap the box back together and then connect the light to the box. This is very convenient to have the box separate from the light, so it’s not dangling while you are wiring the box up. Then just simply test the light by Turing the power on and then off. Then use the spring snaps to secure it to the ceiling. We had some difficulty with a couple of the spring snaps coming apart, it was time consuming to get them back together, and in working order.I emailed the seller and let them know that there was a problem, they were super helpful and I couldn’t be more pleased when they sent me a new light.Here is the snag.... they now have a new style of light, so the whole second box and the replacement they sent is the new style. The voltage outputs are different and the light colors are just slightly different. It is not a lot, but the new lights have just a hint of incandescent compared the the very white white of the old style.Either way, I am happy with the customer care for sending me the replacement light.I installed all the rest of the required lights without incident (I had to buy extras due to they way they are sold). So if something does happen or I want to swap out something else in my house, these will be helpful.It is now February 2021, one of the kitchen lights pictured just went out. It was again something wrong with the internal components of the junction box. I have not contacted customer support about this light.My final thoughts on the product:-We love the lights!-looks great!-They are easy to install!-good price point!-great customer support-concerned about longevity of product
