Underwriters Laboratories and ETL Intertek are 3rd-party testing and certification companies. A product that carries a UL or ETL Listed Mark has undergone testing that confirms it meets national standards for safety.
All of our sconces, including marble, ceramic and brass versions are either ETL or UL Listed.
Because our pendant fixtures are custom fabricated to order with different cord colors, we are not able to certify them across the board. Instead, we allow our customers to choose whether or not certification is a requirement for their homes and offer UL Listing as an 'add-on' service.
Note that our certified and non-certified lamps are made with the exact same fixture and components. The only difference is that the certified fixture is sent to a testing service and then stickered with a UL Listed mark.
Generally speaking, all commercial and hospitality projects will require UL or ETL listed fixtures.
Occasionally, your local electrical code may require certified fixtures for residential buildings if there will be a DOB inspection at the end of the renovation process. We suggest that you confirm with your electrical contractor what the local requirements are.
If you are simply swapping out an old lamp in your home for one of PERN BAAN's lamps, then you probably don't need certification, but again, you should consult with your electrician.
Some customers who don't technically need the certification will still purchase it. Think of the UL or ETL sticker similarly to how you'd view 'Non-GMO' or 'USDA' certified labels. If it gives you peace of mind, then it might be the right fit for you.
