Rectangle nodes waterproof?

[diceman3807]

I ordered several sets of the rectangle nodes (You are not allowed to view links. Register or Login) from Ray, and the first set I got back were inconsistently sealed. He agreed to send me replacements for the items, and these also seem to be inconsistently sealed. I was expecting the clear covering to completely encapsulate the LED's and components on the rectangles. Is anyone else experiencing the same, or am I expecting too much and this is not going to cause issues?

just go to harbor freight, and pick up a can of clear spray on electrical tape. make sure it's clear!   then coat your nodes. I'm doing that with my plastic rectangles just to be safe.

It is Plasti dip made by Performix.

Use the spray version. I bought a can at ACE and it did 50 stars with 3 rectangles each with some left over.

I tested it in the shower and it rained during my July 4th show and there were no failures from water.

Due to time constraints I am not taking this additional step so I am the official tester I guess.  All of my modules seem sealed with the exception of the chip as in your pics.  Might throw a set into bucket of water and find out.

My square modules (metal shell, four 5050 chips) also have some IC chips without full coverage. The leads are covered but the plastic is not quite covered.

I'll probably visit Home Depot and get some sealant just to be sure. They're going on the roof in full sun and rain.

As long as the conductive parts are covered I would think it would be sufficient.

Thanks for all the information guys...

Submerged a good tested set into a bucket of water for 12 hours and just tested again and not a single problem.  My nodes look identical to the diceman's: all but surface of IC covered.  Will report back again in 12 more hours but I am going with mine as is.

That's helpful Sam. I was going to coat them as I just got some from Ray. I will leave as is.

Submerged for 24 hours and no issues.  I am going with mine as is.  If it ain't broke don't fix it...
