Underwriters Laboratories (UL) recently announced that it has been named an authorized testing laboratory for three new Zhaga Books — Zhaga Interface Specification Book 4: high-intensity LED light engines; Zhaga Interface Specification Book 7: indoor light engines with separate electronic control gear; and Zhaga Interface Specification Book 8: socketable LED light engine with integrated control gear (85 mm base).
Zhaga is an industry-wide cooperation aimed at enabling the interchangeability of LED light sources made by different manufacturers, as well as developing standard specifications for these sources. Zhaga standards cover the physical dimensions, as well as the photometric, electrical and thermal behavior, of LED light engines. Standardization is expected to prevent market fragmentation into incompatible products.
These three new book accreditations come in addition to the two books UL is already authorized to test for — Zhaga Interface Specification Book 2: socketable LED light engine with integrated control gear (65-mm base) and Zhaga Interface Specification Book 3: disc-shaped LED module with 9-23 mm light-emitting surface.
