Questions about purchasing a Robo-Tank DIY Aquarium Controller Kit

[Rob F]

Don't quite understand why they would do it this way, I guess to sell a controller. Its probably a few dollars in parts for the dimming circuit that should be in the light. All their talk of an external controller is nonsense if you need their controller to use it and without theirs the warranty is void... But yeah it can be done just need a LDD driver and bigger power supply like the one you linked.
