Book 16:
Planar circular LLEs

Book 16 defines a family of planar, circular LED light engines (LLEs) with an integrated driver. Such LLEs are especially suited for use in flat, circular, low-luminance applications.

 

Book 16 has five LLE categories, defined by their maximum diameter. Two more sub-categories allow easy mounting in existing luminaires.
