24 hour sunrise/sunset dimmer for mains power light?
(1/4) > >>
tekdan000:
I have a cube aquarium that I need to light with a single light bulb. I found the perfect bulb and whatnot. I have a tc420 led strip controller that has 5 channels and 12v 4a per channel output. The controller is used to dim the lights with a set timer curve. So it mimics sunrise and sunset and stuff like that. I'm a noob to this stuff but I read somewhere that I need to mess around with the mosfet inside this controller to be able to use a pwm dimmer or something like that. Don't know if I'm right at all here but I'll put links to everything I am using. Please help me out as I have no clue how to make this work.

It seems like you should use the LED strip lighting that goes with your controller. The bulb you showed is completely inappropriate as it is a mains voltage LED replacement lamp, not low voltage LED strip lighting.

The strips didn't come with the controller but strips are more appropriate indeed. What I'm mostly wondering about is if I can get some kind of controller to work with 120v bulb

First, all above 12V in an aquarium is a wary bad idea! The fish can get killed or if even higher, you can get killed!!

There are a heap load of things you have to consider while working with light to an aquarium and often is it better (less fun) to just bye the right gear, to avoid cooked fish, random shortages, fires and a lot more that your insurance will not cover!!

In Australia the overwhelming majority of submersible heaters and pumps are 240V, as are non-submersible air pumps and lights.

Substitute with mains voltage of your choice, but I don't think it's different in other parts of the world.
