How water resistant are non-waterproof LED strips (Electronic Question)

Transisto said:

I am considering using LED strips (3528) on the fire extinguisher pipes in a room that accommodate a lots of people about once a week. My concern is about moisture condensing and dripping onto them.

I was thinking on removing any salts and impurity by cleaning thoroughly the pipes or repainting them before applying the LEDs.

I currently test with a strip with the last two feet in a water bucket and it seems not to affect them, (2hrs now).

What I think would happen is the LEDs may get brighter due to lower resistance of the "151" resistor. This and the power supply protection may tip if it's sipping to much power.

Your thoughts ?

Condensed water by its very nature is distilled and pretty much non conductive. It gets its conductivity by picking up residue on the board.

You may end up with some corrosion.

Are they on all the time? If you are concerned, buy a small jar of silicone conformal coat and coat the board.

Update : They started blinking, The problem happened at the junction used to solder them 3 by 3. Some blue matter appeared at that location.
