I have a request for an led internally lit 16" x 16" 2 sided cabinet with a max of 4" depth. This cabinet will hang from a ceiling. The request was satin stainless. I have not been able to source one in stainless. I have in the past wrapped some sign comp cabs in stainless which worked well. I can also fabricate my own out of stainless if necessary but I am not sure how the UL certification would hinder it. I was under the impression we did not need UL listing on the led cabs since they were a low voltage source. Am I wrong? Please forgive my ignorance on this topic.. I would be grateful if someone had a source they could point me to for a supplier. Thank you all!
