It does seem like some sort of controller issue. However, I put in a new controller when I first started messing with the lights. The four that I was working with are the lights right under the control panel that have new sockets and new bulbs. I tried different bulbs and still got the same results. I tried the 4 again today and I can get 3 blue then when I start going thru the colors some go on and off and then go into a strobe like flicker and you have to unplug the controller to get back to blue. The last thing to replace is the power supply. It is putting out 5vdc but could be weak under load. I looked up the company that made that setup. Rising dragon tech is the company. They still make a 2 wire bus setup but don't have the front access bulbs listed. Now they make them with a front access lens that has a single POL bulb that goes in from the back. I have been digging thru spa building supply sites looking for some kind of single or double light setup that I can use. I found one made for swim spas but It just had the two puck lights and no lenses. Since the sites sell mostly to spa builders there is not much info listed for the kits. We have been using some floating lights from Academy too. They look cool but not as cool as having 32 underwater lights at the touch of a button.

Today I was able to bypass the tub and run fresh water thru the circ pump into the heater and out into the grass. With the inside of the tub dry I was able to get in and work on the lights. I cut the red and black wire at the first corner to isolate the first 6 lights in the run. I unhooked all of them and started plugging them in one by one. I can get three to work together and cycle thru all colors. As I hooked up more lights they got wacky and out of sync and would randomly shut off. I was always told this was just a moisture problem. The tub has been empty for a week and the bulbs are good and dry so I know there is no moisture and I cant even get 6 to operate together. My next plan is to run a new piece of wire and stab the connectors on a fresh wire and see if it makes a difference. After that, I am out of ideas! Yall don't be shy post up some ideas or feedback!

Let me know how it goes. There is not much info out there so its good to talk to someone with the same problem. I am waiting on 6 new bulb and socket sets to come in. I have a few sockets that look a little corroded so I will replace them too, they should be pretty easy to get to. It would be a lot easier if you could work on them with no water in the tub. I thought about bypassing the circ pump and heater to pull fresh water from a bucket (with a water hose keeping it full) and then just discharge in the yard. This could keep the controls working and keep the pump and heater from burning up so I add one bulb at a time. The other thing I think about is longevity. IF I do get them working, how long will they stay working? As prone to problems as these things are will they just stop working again soon. I agree they are parallel but what makes the colors change? Christmas lights are just power on, light comes on. Power off, light goes off. What does the controller manipulate to get the smooth color changes?

The biggest issue in getting to the sockets and the wiring is the foam. The side and back compartments are completely foam filled. I drained my tub today and found 4 bulbs that were questionable and two that were broken. I'm going to do a good socket inspection with a flashlight before I replace the bulbs and fill it back up. You might check your power supply output for 5vdc. I have read If there is moisture in the bulbs for too long it can burn up the power supply.

I am about to do a water change in the next few weeks and I will mess with it again. I'm not sure it is even worth it anymore. Two of the bulbs that I have replaced with brand new ones have already broken. The lenses have broken off and ended up in the bottom of the tub and the price of the bulbs just went up to $10.37 ea. I didn't buy my tub new and I got a good deal on it because of the fact that the lights didn't work so I cant be too upset. However, I consider myself pretty handy and it is very frustrating that I can not get them fixed. If the dealers don't want to mess with them they should at least release some diagrams or diagnostic info.

I like your plan of putting the tub in summer mode and pulling all of the lights. On my next water chance I will defiantly have to give it a shot. I can't get to all of the snap in connectors since they are all inside of the foam with the exception of the ones that connect inside the front panel. Currently when I turn on my lights I get the 4 corner lights and the waterfall light in blue. Sometimes I get 8 or 9 random lights inside of the tub that will light up blue but pretty dim. Sometimes I can get in to the menu to change the colors but as soon as it hits the color red the menu will become unresponsive and you can not even turn the lights off at the control panel. I have to shut off the main breaker and restart the tub to get them to turn off. I bought my tub used with the knowledge that the lights did not work but it is still frustrating that there is no easy fix and no diagnostic info out there. Keep me posted on your progress and thanks for the reply!

I have the same problem. However I am only getting 110v into the power supply. I have replaced all the bulbs and the controller. I get the 4 speaker cap lights and waterfall in blue but that is it. Light menu does not even show up on the control panel. If anyone has any information I would appreciate it!

Update: I replaced the controller and now the topside corner rings, waterfall light and 8 of the tub lights work but I can only sometimes access the light menu from the control panel and it will lock up after the second or third color option.

I bought a used 2008 Limelight Pulse knowing it had a issue with the LED Lighting. The previous owner had a spa tech replace some of the led's and sockets already. I have read on some previous post that it is best to just go ahead and replace them all so I replaced the rest of the "points of light" that were not already done. While pulling the old lights I noticed that a few had condensation inside and behind the bulb. I blew all the sockets out with an air hose before putting the new light in. I have 5.5 VDC coming out of the power supply so the next thing to replace is the controller. Any other things I can try?
