RGB LED Bathroom shower light project problem. ? Answered
I finished two bathroom reno's with the exception of the shower ceiling light.
I started off by cutting 3 1/4: square 304 stainless steel plates and drilled out 4 holes in each for the rgb. Then assembled the rgb's into the housings and sealed them with hot glue. Then figured out the resistors based on 12 V which if memory serves me right they were 470 ohms and soldered them in parallel. Then I soldered the connectors and hot glued them so they wouldn't come in contact with each other.
After installing the ceiling tiles I drilled 2 1/4" wide X 2½" deep holes through the kerdi membrane and sealed a plastic cover with foam insulation in the attic. Then I roughed in rgb cable from one hole to the other, with a home run to the controller.
I tried doing a rough in trial run and it worked until one of the rgbï¿½s burned out since they came in contact wth each other. I could actually hear it fizzle.
Anyone have any suggestions on how I can make this work or are there retrofit rgb units that will fit the opening without breaking the bank? Each bathroom has 6 rough openings. That would make it 6 x 2 = 12.
I'd like them to be rgb leds and be controlled via 12V adaptor and controller. If I need to start over again I have a budget of $150.00 if a another unit would work better.
