## Most critical reviews (6 lowest-rated)

### 1/5 — Awful

*2025-11-23, version 1.1.7*

App doesn’t work, can’t even enter a password for the light as the connect button is greyed out. Clearly don’t care as someone else 4 years ago has the same issue. Happy to take my money though.

### 1/5 — Not connecting

*2020-10-27, version 1.1.3*

It won’t work 😞😞😞

### 1/5 — Asks me to enter a password without allowing me to connect

*2020-05-28, version 1.1.0.11*

When connecting to the lights I am prompted to enter a password, I can put a seemingly infinite numbers in but it still will not allow me to submit any password and then connect

### 2/5 — Very poor

*2019-09-09, version 1.0.8*

Good colour spectrum but why can you not get it to hold a setting? You can set sunrise and sunset, but every morning you have to reset colours. Hopeless...nowhere near as good as AI Prime

### 3/5 — TMC REEF PHOTON

*2019-03-09, version 1.0.3*

Overall happy with spectrum of light but needs a light off in the advanced settings for those of us who like no lights on

### 4/5 — Good spectrum of light

*2019-03-14, version 1.0.3*

I do really like these light, the colour ranges are great. 

Only down side, I can’t get them to switch of at the end on a personal setting.  Lights go out, but come back on by themselves in a dull blue.
