Socketable, circular LLE with maximum dimensions of 95 mm diameter and 45 mm height, and a PHJ85d base.

Book 8 is essentially a larger-diameter version of Book 2.

Several Zhaga Books (Books 2,5,6 and 8) describe circular LED light engines and circular LED modules that fit into circular sockets (also known as LED holders). These products offer the possibility to design luminaires in which the LED light source can be removed and replaced without the use of tools. [Note that replaceability depends on the luminaire design and is not a feature of the Zhaga specifications.]
