Luminoso 13W, 4000K Downlight Light is an amazing combination of price and performance. It provides advanced dimming parameters with capabilities reaching to as low as 10% and works with most widely available traditional dimmers. It is designed to easily install into existing IC or non-IC 6 inch housings. The DL Series provides higher efficacy and longer life than a compact fluorescent lamp, with the same beautiful light quality that you would expect from an incandescent lamp. All of the above mentioned features make this product ideal for new construction or retrofit applications.
