• Simple dimmer for a mini aquarium (need help)

  • Antonio

I have a light fixture with three stars: Cool White XT-E, Royal Blue XT-E, and Blue XP-E on two APC-16-700 drivers, one for the white and the other for the blue. I need to reduce the brightness of the white string. Please suggest any way to do this with minimal costs. I've heard about controllers, but they are too expensive for me. The price should not exceed 450-500. Thank you for your attention.

So far, I've dug up this scheme. I don't know which components to choose to make it work with Cool White XT-E.

Brian

Have you tried googling? up to 300 ))

Gabriel

Thank you, two channels, 500 it turns out, there is a controller on the forum for 4 for 30 bucks - 700.

You said one channel needs to be connected, right?

Wesley

Thank you, yes, in communication, the truth is formed. If there are 4 channels, ideally, in a box of 700, then one should not exceed 200-250, the acceptable price!!!

Please let me know where exactly we have such a controller for $30 (give me a link here or in a private message).

I think links within the forum, within the rules, catch them.

Thank you, but unfortunately it doesn't work for me; I need per-channel brightness control by hours, and there are no hours there, only relays per day.

Joe

then you should go to airsoft, or Pastuh1234. Good luck,

I found a solution to my issue, it looks like this. Now the question arises: if I solder a variable resistor to the driver, will it work as a control substitute???!!!

You can solder anything to anything! But you are really creating some kind of chimera. Option 1 (the cheapest) - your power supplies have a divider (shunt) that measures current (700 mA). If you have a friend who is an electronics expert, he can select resistors for you for 50 and connect a potentiometer! Then you can adjust your power supplies, say from 300 to 700 mA (marine aquarium)! Option 2 is to build the controller yourself! The budget is 500 UAH (but you need to understand a bit about electronics).
