Did you recently purchase a Bestway brand inflatable bubble spa hot tub? Were you wanting to put LED lights in your tub to be able to use it at night but couldn't find one made for your spa? I might have a solution for you.
The LED light
The LED light we are going to use for this is one made by Intex for their PureSpa line of inflatable hot tubs and bubble spas. I have seen these listed under 2 different models, SL503 and B01NBYH7O8. This is a multi color LED light that illuminates White, green, teal, blue, and purple and can be set to one solid color, or to a color change setting that will cycle through all of the colors. The LED light creates the perfect ambience for your hot tub/spa experience. This LED light can be purchased from Amazon by clicking here. More information about this light can be found on the intex website by clicking here.
Making it fit the Bestway spas
I did a bit of research into LED lights for the Bestway spas and found that nobody makes an LED that fits them. In my research though I found a comment on the Amazon product page for this light where someone stated that they just pushed this hard onto the water outlet on the spa and twisted a bit and was able to get it connected. I figured there had to be a better way. The model of spa that I had to test this with was a Bestway SaluSpa Miami. The Miami spa has a piece that looks like this, which is used to put chlorine tablets in to keep the water clean. This same piece is found on other Bestway spa models such as the SaluSpa Paris, SaluSpa Hawaii Which are models sold in the US. Other models that use this adapter include some of the Lay-Z-Spa models which are models sold in the UK, such as the St Moritz and possibly others.
The piece described above fits on to a piece like the one on the left which attaches to the water output port of the heater/pump. It fits on to this piece by twist locking into the channel marked in red. Looking at that and the threads on the Intex LED light, I figured I could design an adapter that would thread into the LED light on one end and provide the twist lock tabs for the Bestway spa on the other. The picture on the left is the adapter that I designed. The picture to the right shows that adapter screwed in to the LED light and sitting next to the original piece that I removed to attach it. If you have one of these spa models and would like to purchase one of these adapters, you can purchase it from my online store by clicking on this link.
In some later conversations with some people that were interested, but didn't think the adapter would fit their model, a picture I was sent from one person showed that the output port on their spa didn't have the notches needed to use this adapter. This gave me the idea to create another version of the adapter that would fit in place of the gray output port shown in the picture on the left.
I modeled the adapter off of the smaller threads of the piece from my spa, and this is what I came up with. This adapter should fit most of the other Bestway spa models that have a 26.25mm (1.03in) threaded port, though it has not been test fitted on these other models. If you are interested in trying one of these adapters, these too can be purchased from my online store by clicking on this link.
Since writing this article, I have designed yet another adapter to fit the Mspa brand of inflatable bubble spas. My understanding is that it fits most, if not all of the Mspa brand bubble spas. The small threaded end of the adapter is 36mm (1.42in), which is a larger diameter than that of the Bestway/Coleman adapter that I sell. If you are interested in this adapter, you can purchase it from my web store by clicking here.
I have adapted this LED light to fit on most if not all Bestway model bubble spas. If you have any other spa or pool model that you would like to adapt this to, feel free to contact me with some information and let me know what your needs are.

Happy relaxing in your newly converted bubble spa.
