Pool Builder installed a Pentair Globrite. It stopped working after about 2 years and was almost never used. Similar model on Amazon lists the price around $479. Pool builder swapped it under warranty and installed a Savi, I think it's the Melody model. They also died after about 2 years, but now the pool warranty expired so all repairs are my responsibility. The price for the Savi was about $550-700 when I looked. Replacing both would set me back almost $1,400 so I elected not to fix them. After looking around on Amazon, I found this set for about $100 each. I bought one at the end of Oct and installed it the next weekend in case I had an issue. I did the install myself as it seemed like a simple DIY. I turned off power to the 12v transformer, opened the connection box, disconnected the black, white and ground and double duct taped a 100 foot clothes line to it, then I went to the pool light, unscrewed it by using a screw driver and gently taped at the outside edge in a counter clockwise direction where there is a notched for the removal tool I didn't have and it loosened up to the point I could use my hand to unscrew it. I gently pulled it out and continued to gently pull the power cord. I had someone back at the connection point guide the line in as I pulled out. Eventually, instead of a power cord, I pulled out the clothes line. I then retied the clothes line to the connection end of the new one and my assistance pulled on the clothes line gently until the power cord appeared. The new LED screwed in easily clockwise and I used their included tool to lightly hand tighten it. I reconnected the power and turn power back on to the 12v transformer and the light came on without issue. Notes: I did drain out the spa in to the pool when I did the first one, but it turns out I didn't have to, but I'm glad I did so I didn't have to grab a mask and go underwater to figure out the removal process. For the second light in the pool, I felt confident enough to do everything underwater and by touch. I didn't take a picture of how I taped the clothes line, however it was pretty simple. Since I didn't want to risk the tape losing its grip and I didn't want to tie a knot risking it get caught on an edge in the underground plumbing, I first put the power cord and clothes line next to each other with the ends facing opposite of each other. Then I used heavy duty tape to connect them. At this point, I could have started to pull the line though, but just in case, I took the clothes line side and made a loop and over lapped like a Z pattern over the power cord and tape it again. This way, the tension when i'm pulling is on the tape holding the extra loop instead of the original tape holding the connection together. It might be over the top, but the 30 seconds it took to do this would save me alot of time if the connection broke loose. With this success, I went and bought the second light and repeated the same steps. I also used their syncing method so both led lights display the same color. I elected for the slow color change so it keeps changing between the 7 different colors. Both lights have been running every night from about 6pm to midnight. We swapped the light switch with a Kasa switch that is automated and can be controlled from Alexa and it also tracks usage. The photo attached show 143 hours for the last 30 days so its been on for roughly 300 hours since installation in early November. today is Jan 11 and they are still working great. at about $200 for both, even if they only last a year, its still cheaper than $1,400 for 2 years of use. They are not as bright as the original 2, but it lights up my pool fine as seen in the photo. Hope this helps!
