LINEAR LIGHTING – COST EFFICIENT, LONG LASTING, SIMPLE TO INSTALL

example OT FIT 50/220…240/250 D L), a homoge- neous light source is achieved with a rated luminous flux of 5 500 lm. “HO operation on the 350 mA LED driver is not possible because the rated power would be exceeded,” he adds. “The modules are designed in such a way that the 860 mm and the 560 mm modules can be connected to each other by simply using a straight cable bridge.”

Combining design and performance … perfectly “The PrevaLED Linear FIT D system simplifies the fitting of the luminaire thanks to the mod- ule lengths of 1 120 mm (1 200 mm fitting) and 860 mm + 560 mm (1 500 mm fitting) and the adapted current rates,” he says, adding that the “design-in of the OT FIT D drivers is very simple”. The 1 200 mm (4 ft) fitting can be equipped with a single module (nominal lumen package 4 400 lm), which only needs to be connected to the selected Optotronic ballast (for example: OT FIT 50/220…240/250 D L). Additional cabling for connecting shorter LED modules with each other is no longer required. “This has a positive effect on the bill of materials and also reduces T he PrevaLED Linear FIT D from OSRAM is a first-level segment for linear lighting appli- cations, providing an efficiency of up to 157 lm/W and a service life of up to 50 000 hours. OSRAM’s Eric Hall says the LED module can be combined with non-insulated Optotronic drivers and operated as a non-insulated system. “The PrevaLED Linear FIT D modules are perfectly at- tuned to the Optotronic FIT D LED drivers and is available in lengths of 560 mm (2 ft), 860 mm (3 ft), and 1 120 mm (4 ft),” he explains, adding that the fixing hole distances comply with Zhaga Book 7 L56W2.

the time required for fitting construction,” says Hall. The 1 500 mm (5 ft) fitting can be equipped with two modules, that is, one module each in the lengths 860 mm and 560 mm. By connecting the two mod- ules and then connecting an Optotronic ballast (for
