DIY light dimmer

I have a 36" finnex stingray on my tank. The thing is, it may be too right because all my EBJD does is hide in his cave. It was suggested to me before to hack my own dimmer into a finnex stingray light that I wanted to use on a planted tank to lower the par. My question here is, can any show me how to do this? Is it fairly easy or should it not be attempted?

It's easy but of course you will void any warranty.. unless you do it "right".

start w/ one of these:

Put it between the power supply and the light

Warranties are voided if..."you alter the fixture or any part thereof".
So put your dimmer in an extension cord which you use between the fixture cord and the wall socket.

The shortest distance between any two points is a straight line...in the opposite direction...

Easiest way is to cut the cord between the power supply and the light.
Strip the wires, attach to the dimmer.. following "in" is from the ps, "out" is to the light..

OH AND keep the polarity correct..

Use a volt/ohm meter to determine power supply positive and negative.
Light will be the same as the wires from the ps. Usually they will be obviously a different color or pattern,

The harder way is to find plugs that match and that way you don't need to cut anything of the Finnex..
for plugs you need to know the outside diameter and the inside pin size..

I think your overthinking it. It is quite simple really..

Easy methods, minimal cost, no warranty issues; raise the light or filter it through a piece of window screen.

Does the stingray have a discrete dc converter? The pictures I've seen seem to suggest wall power enters the fixture.

Most implications just have it hard wired but still w/ an external brick:

Yeah, my 24/7 (4 months old) came with that waterproof screw-on connector at the power supply, but neither my Planted+ (13 months old) nor my Stingray (5 months old) have connectors. The power supply is just hard-wired to the light in older models.
The clip on ones are probably the exception though. I know the old style is built in to the base..
