Jay and his crew are extremely talented and install LED lights with extreme precision. Our jewelry store has over 30 showcases and shelf units that are custom made and expensive. Jay took the upmost care while installing his LED lighting. Jay only installs the best grade LED lighting and does not cut corners with inferior materials. Once the job was finished the difference was night and day compared to the old lighting. I highly recommend using Jay Seo and his crew to upgrade to LED lighting. You will not regret it!
