Using cheap light controller on chinese black box led

[Willbiker]

These aquarium light controllers can accept an input voltage of between 12 and 20 volts and up to 100w.


The black box leds has 2 drivers which output about 80w each and I believe their output is 12v.

Would connecting this controller between driver and leds successfully dim the leds?

Depends on the type of leds

 

[Willbiker]

Can you elaborate?

 

[sam2110]

Some LED chips are dimmable others will just flicker if you try to dim them

 

[Willbiker]

The unit already has dimmer knobs which I assume adjusts the voltage to the leds....the same as what these controllers do.

Hmmm

The only way to find out is try it, its not massively expensive

 

[Willbiker]

Anyone else got any thoughts on this?

I highly doubt your "black box" driver outputting 12v, because that would power about 3-4 LEDs.

Most drivers in these boxes are 80-100v output per channel. Then, some are dimmed via 0-10v analog, some 10v PWM, and some 5v PWM.

So long story short, this gadget is not likely to achieve the result you desire.
