Dimmer for TITAN 1

A friend of mine got TITAN 1 BY ULTUM NATURE Titan 1 Premium Aquarium RGB LED Light For Planted Tanks - Ultum Nature Systems that unfortunately comes with no dimmer. The sales person said something along the lines "you just need a 3 pin dimmer" which I am not sure what that would be, but I hope you guys can help.

The power supply reads Output: 36V 3.0A. The connection is 2 pin round plug (as seen on the manufacture site).

Would something like this (except for 36V not 12V) https://www.amazon.com/SMY-Controlle...xCKAQrgHEII4Ks work.

Could not find 36V on amazon, so links would be appreciated.

Would this work from evil site item #153640107950 and #183491521938?

Any suggestion or links are greatly appreciated! Ideally, if the connectors would match, but this is not a deal breaker for sure!

Well first the "weird" type of dimmer.
Apparently they PWM the AC line to the power supply.. AFAICT.

Secondly. PWM motor speed controls "should" work..
Generally their PWM frequency is just a lot higher than normal LED light dimmers but "shouldn't" be an issue.

jeffkrol, thanks for clarifying the matter! very helpful. Initially it crossed my mind that a light-switch from hardware store is what they have in mind, but they proposing this for $$$ light would be silly Apparently not! Anyway, I would avoid this road, at least for now.

Good to hear that I was going into correct direction. We will try it out with one of those dimmers, and update later with the outcome.
Thanks!

well, since we are here, jeffkrol do you happen to know or identify for me what kind of sockets are used in this light, between the power supply and the light? It would make sense to match the existing ones, rather than cutting the cables etc.

Doesn't look to be "standard" (if there is such a thing)

Sorry not much help The small one in the lower right corner looks "D" shaped.
Didn't thoroughly search that site though..

A hack isn't going to come easy for this light. Just hang it higher imo. I still need to fab a "lamp shade" on mine the spillover is insane on this thing.

Hmm, I don't know about that..
I can see the possibility of brass rod and tube to make a custom plug.
As to dimming.. do need to look a bit into it..

They are putting more constant current drivers on boards nowadays..

Only place you see non dimmable LED lighting is in the Freshwater lighting space. You never see this in a reef tank lighting they would not even think about shipping an expensive LED fixture without dimming and WiFi app control. It would not even sale.

JeffWW - do you think the ADA RGB shades would fit on a Titan 1 light? The shapes are very similar although I know it would be a leap of faith and a wild assumption to think they are exactly the same.

Jeffww, did you try to hack it with the above proposed methods and it did not work? Or maybe somebody else tried? I looked around and could not find any info on this.

update: no luck with dimming this light. Tried to run through "PWM motor speed controls" and while it dims, the color temperature changes from daylight to a very warm one. So, it will not work. Tried also a regular dimmer from hardware store, and this method does not work at all; it will not react to the dimmer till half way, then it will turn off completely.

The positive side: the light looks very nice, and it is very well build. Just bad that for $$$ light, the manufacture could not chip in a dimmer.

Well that warm to cool look would be good for a sunrise/sunset effect..
Sort of odd. normally when RGB stuff is globally dimmed it gets bluer or magenta...

Looks like the manufacturer makes a dimmer for this light

only $11

Edit - I may have been too hasty. Not sure if this model works with it Sorry
