### 1/5 — Bluetooth is broken

*2025-10-14, version 3.57.160*

Telling me that Bluetooth isn’t on when it is. Bricked the device because this app is horrible…

### 1/5 — No update

*2025-10-05, version 3.57.160*

No update for this app, and the new version won’t link with my spotlight. Total waste of money.

### 1/5 — I regret ever buying these lights and getting this app..

*2025-09-21, version 3.57.160*

This app is garbage,.. just more absolute trash from chynah that works ONCE,.. then it’s all over, and good luck getting any support, there isn’t any,.. they got what they wanted, our American dollars,.. but never again.. if it isn’t made in the USA, I’ll never buy it.. cheap chinese garbage made by slave peasants being paid in rice and bok chow..

### 1/5 — i bought 2 flood lamps

*2025-09-12, version 3.57.160*

one flood lamp changed to flash mode on it’s own. if i had epilepsy i could sue. the app is newly updated and says “the APP is too old, please install the latest version!” … now i can’t change the settings for the light. terrible app and product.

### 1/5 — Horrible

*2025-09-07, version 3.57.160*

Junk app. Doesn’t work at all.

### 1/5 — Dead App

*2025-08-12, version 3.57.155*

I’ve used this app since 2022, when I bought some landscape lights it was used to control. It could be temperamental, but worked well enough that last year I bought another batch of lights. This weekend, the app suddenly renamed itself on my phone with Japanese characters and claimed my Bluetooth was disabled, which it was not. I deleted and reinstalled. Now it won’t find my lights. The support link does not load a page—site times out. If you have purchased a product that uses this app, return that product immediately.

### 1/5 — Does not connect

*2026-01-10, version 3.57.160*

*2025-11-29, version 3.57.160*

### 5/5 — Smart apple

*2021-06-09, version 3.19.7*

Great app, easy to control, very smart

### 3/5 — Please update app to fix brightness while in pulsating mode!

*2022-12-15, version 3.19.15*

Hello, 

Just got the landscape spotlights.  I downloaded the app and setup the lights on it. Please please please update/fix the App to have the brightness adjusted while in pulsating mode.   It automatically reverts to full brightness when put in pulsating mode.  Then when you go to the brightness tab, it stops pulsating mode.  Then back into pulsating tab and it goes straight back to full brightness.  This is so irritating,  it’s far to bright for my little palm tree.    Please fix this issue.   Thank you.

### 3/5 — Can’t control two lights?

*2021-10-17, version 3.19.10*

Like another reviewer, I bought two floodlights. I turned on one (plugged it in), set its nickname, and unplugged it. I moved the first, and then repeated with the second. 

I took both outside to plug in, and…voila, they worked. I went to change the color of A and both changed. I went to change B, and they both changed.

I simply want two lights with two separate colors.

### 3/5 — i bought 2 flood lamps

*2021-10-05, version 3.19.10*

i bought 2 smart led flood lights and was wondering if there’s a way to have them project 2 different colors?? 3 stars bcuz there are limited color ways.

### 2/5 — Does work!

*2025-04-05, version 3.19.15*

They don’t tell you how to do it so I will. Open the app and it will have a few pre downloaded fans. Click one leave it open and turn on and off your light switch three times quickly. Light will flash and it will connect. Good luck.

### 2/5 — Yard flood light

*2024-08-22, version 3.19.15*

I got a set of 4 lights for the yard. 
I was able to set up 2 of them. The third one is not setting up. And I can’t find any instructions on how to set up all of them together.
