We had the opportunity to test the new ATI Straton thanks to Jonathan that has just bought three of them for his tank. We analyzed the PAR and created the distribution curves. Let’s see how it went.

The ATI Straton is a LED ceiling light available on the market since last year, then due to the Coronavirus and the well known slowness of ATI, is distributed with the eyedropper. Despite this, we really like this ceiling light, both because of the distibution of the LED and for other things we’ll reveal in this interview. The ceiling light is very thin and uses a passive cooldown, that’s the critical point always comes out about this ceiling light.
Technical characteristics of the ATI Straton
The ceiling light is square, of about only 14 millimeters high, has 7 LED of different colorations divided in 7 channels, so each channel sets one LED only. There aren’t any LED for moonlight that are present in other ceiling lights. The LED aren’t distributed but grouped in set of 4. Moreover, Straton has logically divided the LED in three parallel bands that can be managed individually, creating different switching, but also dimming the bands in case the temperature goes over 55 degrees, without switching them off.

Construction
The construction of the ceiling light is flawless. There aren’t any creaks and the structure is just so solid. We know that inside the aluminium works as heatsink, but we don’t know precisely how’s made because we didn’t disassembled it, even if we were extremely curious. There aren’t buttons. The ceiling light turns on when it connects to the power then is set through wifi. I would have preferred Bluetooth, but we’ll see this detail later.
The programming
The ceiling light has to be set through a webapp. This means that there isn’t a specific app, but a website for our browser. This solution is more powerful because allows any device with a web interface to interact with the ceiling lights, but it’s less easy to be used because not all the device can visualize the page well, and the access configuration is not that intuitive. The webapp, actually, is available only in English or Dutch. We used the English version.
Here above there’s the chart where we set the curve. In order to make it simpler we made a video in which we connect and set the ceiling light, so we won’t have to spend too much time on this topic. Above there’s the basic set that switches on the bands of the ceiling light.
You can create or modify the curves, or even choose one from the available preset. We always recommend this choice, unless you know perfectly what you’re doing. In fact, with a ceiling light that allows to change all the channels is extremely easy to create problems to the corals lowering too much certain channels or forcing others too much. On the lower left there’re always the temperatures in real time.
One last note about the curves: you first have to set some channels per color, then bring them to the curve. It’s not very intuitive, but once you’ve understood it’s not that difficult, even if requires more time than usual.
Channel 1: UV
Channel 2: Purple
Channel 3: Royal Blue
Channel 4: Blue
Channel 5: Cyan
Channel 6: White
Channel 7: Red
