First products certified according to Books 4, 7 and 8

The Zhaga Consortium has certified the first products for three different LED light engine specifications. Products have been certified according to Zhaga Interface Specification Book 4, Book 7 and Book 8.
Certification allows products to carry the Zhaga logo, and ensures that all the requirements of the particular Zhaga interface specification have been met. Zhaga certified products are listed on the Zhaga website at: www.zhagastandard.org/products/certified-products.html.
Zhaga Interface Specification Book 8 defines an LED light engine with integrated electronic control gear (ECG) and a round drum shape. The light engine is likely to be used primarily in down-lighting applications.
BJB GmbH has received certification for LED holders designed according to Zhaga Book 8.
Book 8 is similar to Book 2, but the LED light engine has a larger base. The photo at right shows LED holders from BJB and corresponding LED light engines from Philips, with Book 2 products at the top and Book 8 products below.
Book 7 defines the interfaces of rectangular and linear LED light engines with separate control gear. These are used in luminaires for indoor lighting applications, for example office lighting. One indoor luminaire may contain several Book-7 modules combined with one ECG.
Several Book 7 variants are possible that have different overall dimensions, as follows: L6W6 (length 60 mm x width 60 mm), L28W2, L28W4, L28W6 and L56W4. The photo at left shows a range of different Book 7 modules with associated ECG.
Book 4 specifies high-intensity LED modules, which are mainly used in street lighting and high-bay applications. The modules have separate ECGs and a choice of size for the rectangular light-emitting surface, namely 30 x 7.5 mm, 42 x 10.5 mm, and 60 x 15 mm.
Philips Lighting has achieved Zhaga certification according to Book 7 for a range of Fortimo LED Line modules (see News from Members page), as well as several Fortimo LED HBMt modules that are compliant with Book 4.
