Rather difficult to find in most brands, the PAR16 bulbs are the smallest of the PAR collection. Due the their smaller size, they make perfect lights for track lighting and decorative display lighting. Do you require a particular beam size for the space? Our JQ Green America PAR16 bulbs come with a beam size of 18 degrees to as large as 60 degrees! Commonly used in jewelry stores, museums, and art galleries, they are small enough to also be used in under-cabinet lighting and antique cabinets.
