LINEAR LIGHTING –
COST EFFICIENT, LONG LASTING, SIMPLE TO INSTALL
Combining
design
and
performance …
perfectly
Energy-efficient and suitable for prestigious area
street lighting of Group A and B roads, the Yoa
from BEKA Schréder offers flexible combinations
of LED modules, driving currents and dimming
options to provide the most cost-effective lighting
solution whilst improving the well-being and safety
of residents. Round, slim and decorative, Yoa intro-
duces a subtle and refined presence in the urban
space. The luminaire offers an outstanding finish,
particularly noticeable due to its elaborated crown
and its patterned glass protector associated with
an embellishment plate for a detailed aesthetic
finish. The photometric engine offers a high-per-
formance photometry optimised for each specific
application with minimum energy consumption.
The Yoa offers an optional downward facing day-
light switch, pre-set stand-alone dimming profile or
Owlet remote management module.

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 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
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
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.”
