Of the 38 lamp types tested for Series 20, only eight were available in more than one wattage (or lumen package). This is a notable limitation compared to conventional halogen PAR38 lamps, which are typically available in multiple wattages. As a result, the ability to mix lamps with different outputs in the same space is currently more difficult with LED PAR38 lamps, often requiring products from more than one manufacturer that may or may not match in color appearance. Introducing complete families of products with multiple lumen packages would be beneficial, and would augment existing families of products having multiple CCTs and/or beam angles.
