That would be a good light for the price, but keep in mind that it is not automatically dimmable or controllable (you have to manually turn the knob on the top to dim the Kessil light. Therefore it is either on full or off, no ramping up or down the light intensity. Where the AI Prime and the Radion's are controllable so you can ramp them up and down, but more expensive. You could also go with the kessils and add one Reef Brite LumiLite LED strip that is controllable or can be controlled with APEX. That way it could ramp up and down and be your dusk to dawn effect before the other lights come on/off. It all depends on your budget and what you want to achieve. If the dusk to dawn effect is not important to you then go with your above choice.
Here is a good video in case you have not seen it yet.
