### 3/5 — Needs improvement

*2026-08-04*

For the most part, this is a decent system however, the lighting units themselves have a tendency to drop off from the Bluetooth connection, and sometimes they randomly flicker different colors without even opening the app. I was thinking someone else might’ve bought this lighting system nearby and somehow they were connecting to my light system, but that is not the case. It seems to be tied to the connections being dropped, and when I open the software, it goes crazy trying to reconnect to the lights and just throws random commands turning the panels on and off rapidly or won’t connect at all. I bought six of these lights and they were not cheap so I’m feeling a bit disappointed.

### 1/5 — Can’t connect to device

*2026-04-15*

Doesn’t connect to device and no clear guidelines on how to

### 3/5 — consistency. Needs work. Fails to maintain settings

*2025-10-21, version 2.2.6*

Not a paid for review by Vine or anything else. This is an honest review. Warts and all
Nice color lights but no different thsn any other led light like this whether they are square or in a bar. 
The setting keeps reverting to half of the full intensity no matter how many times I set it and make it a settimg preset. 
These lights do not have a consistent timing option. The app should have the ability to turn off and on at a certain times but it does not work that way. 
There is very little instruction as to how to do this if it is even possible   
What instructions there are, are not intuitive or appropriately American  translated aka Ok if you don't speak English but translation to English is confusing or missing full directions. This is a fault of Amazon for not insisting or providing a better translator   
Amazon should deal with this issue for as much as they charge the sellers. 
at least have staff who's user-friendly and will be tasked with trying the instructions and then correct them 
Basically tje Instructions are lacking altogether. 

The app designers failed to take into account the different iPhone sizes so the on off button actually hides underneath the top of the menu bar so one cannot access it again software quality control stupidity to not have made this more  user-friendly. 
In addition one cannot access the additional settings because they're also under the top menu bar and there's no way to tap on them without just initiating Apple settings 

Basically you have to set both the lights to one color and that is it. It is not like Melpro Square wall washers where i can have a variety of options from the amount of time it stays on to the variety of cycles i can create.
I don't want a wall washer that is super complex I just want it to be able to be let's say purple and orange for Halloween. The lights are set to the same light and that is it  - there is no option to alter them to be contrasting. I was provided with one remote for two units
I don't want to get into DJ professional DMX style wall washers. Just had hoped to get something that was a little more user-friendly and would provide me some contrast or variables that have to be a software engineer in order to operate   
With that said these are fine lights if you just want to set them to one color and leave it and turn them on yourself or get a reliable timer 
So far I just turned them on at duskand turned them off in the morning because every time I set a time for let's say for 5 hours it never works

So the price is not bad and if you don't mind having to turn the lights off manually or on the color is good, the price is right.

### 2/5 — Redesign

*2025-10-15*

Please please please move the power button to the bottom of the screen! The power button in the application is right in the middle of the notch on the top of the screen for newer iPhones

### 5/5 — Good

*2025-10-07, version 2.2.6*

Good

### 5/5 — Works well after 2 yrs

*2025-10-02, version 2.2.6*

Five stars

### 2/5 — Wrong size/format on iPhone 15/16/.. with notch.

*2025-09-27, version 2.2.6*

Wrong size/format of app don’t work good on iPhone 15/16 with notch.Menu and settings not reachable.

### 4/5 — Not bad

*2025-09-01*

I use  these lights for my gig.The brightness is impressive, but the only drawback is the limited controls. I hope they provide more options for us to be more creative with the lights. Nonetheless, I still appreciate their affordability and overall performance.

### 5/5 — APP NO LONGER WORKS

*2025-09-01*

The bluetooth is not connnecting. Phone says it is, but the app is not controlling the light. The settings buttons are not lined properly on the newer model iPhones so it’s not usable.

### 1/5 — Let There Be Lights

*2025-05-25*

The app doesn’t consistently connect to the lights, which means you must turn the lights on by physically touching the power button on each light.  
I was unaware of this detail.  The lights were to be placed at different heights some unreachable without a ladder.  This doesn’t work at all for the purpose the lights were purchased.
