I'd spray it out with a dielectric cleaner really thoroughly, then let it sit in a bag of rice for a few days.

Actually, pure water is not a good conductor, more of an insulator. The impurities are what makes it more conductive. We use water for cooling on the stator in the main generators at work, which are capable of producing 380 mega watts of electricity at 22,500 volts... Pure water =/= conductor.

Agreed. Letting it sit in front of a fan for a couple of hours after sopping up what water is visible, First, then what's stated above^
No compressed air, just a fan.

In the south we know all about putting things in rice, with our humidity and all. We even have rice in our salt shakers to keep them from turning into salt blocks.

Agreed, in your case it's insulated from ground. When not insulated, it will travel through it to ground, depent on amperage and voltage.

Even our 0 TDS RODI water will be no where near pure literally just H20 with no impurities conductively speaking. Especially since the error of the standard $20-30 TDS meters and our RO systems.

LFS dropped 2 x zetlight into the frag tank. Called me to the rescue. What i did was took the electronic boards, high pressure air blower drying, decent amount of contact cleaner spray, fine bristle brushing on every electronic components, air blowing, repeat a few times. Final contact cleaner spray, leave to air dry. If you have silicone spray for electronic board, apply and let it dry before assembling. Don't forget the LEDs needs cleaning as well. If it fires up and running, it should last till it fails.

Exactly what I would have done
Here we go.
Take the covers off if you can.
Yes rinse it with RODI if you have it, if not get some rubbing alcohol.
Yes the lower the TDI the higher the resistivity of water and the better ?dissolvibility? of the water.. it is used to clean circuit boards and such as it will leach minerals and oils off of surfaces, this is why it is a bad idea to drink RODI water.
If you cannot remove the cover to air dry, place in a sealed bag after rinsing and put rice in the bag, the rice will absorb moisture.
The place where you will have an issue is in the led pucks / or where there is plastic coverings and such where the water will be trapped.

Works perfectly if done properly. Pay special attention to mechanical components (relays, switches, snap in connectors, power input plugs) and display panel. They are more likely to fail.

This would work......but if we are talking about the average diy person like myself, who would have to buy all these supplies and hope it worked vs buying a $90 black box led. I would just buy new personally. If we are talking a $800 fixture or something more expensive I'd be asking you exactly what I would need
I'm also speculating it's a black box

Agreed. I still covers my ears and close my eyes before switching on any repaired electrical appliances LOL
I've dropped a light before. While I didn't soak it in rodi to get out the salt I did disassemble the light completed and lightly rinsed it off with rodi on the leds and housing and alcohol on the board. Then dried it out for several days and you couldn't tell anything was wrong. One thing to look at though would be the power cord. The power cord had arched a few times and I didn't trust it so I got a new one

Put it in a big bucket and use rice -which will absorb all the h20 and moisture. You'll need a lot of rice but I've seen soaked ip and all types of electronics come back from this method alone. Good luck

Drying alone without proper action to remove residual salt is 100% confirmed failure, probably sooner than later. The semiconductors and other electrical components (resistors, caps etc) will rust in a day or two, salt residue is very conductive and will short circuited semiconductors as the "legs" are tightly arranged. Salt crystals will fill the tight gaps and shorted it.
I actually just did this sorry about it
From what i know, you gotta get the saltwater off it or itll rust the parts. So dunk it in ro/di a few times. Let it dry in the sun, then put it in a zip bag full of dry rice to adsorb the humidity and any subsequent moisture that comes out of it. Good luck!
Even better would be a dehumidifier thing for food that makes jerky.
