5 W, 7 W, 11 W / 12 V energy-saving lights
The electronics of these 12 V DC energy-saving compact flu-
orescent lamps (CFLs) was developed by Steca and continuo-
usly improved.
Preheating, a high electronic efficiency and low thermal losses
increase the service life of these CFLs to about 100,000 switch
cycles. The Steca energy-saving lights feature a much higher
efficiency (Im/W) than LEDs or incandescent bulbs.
Product features
Brightness of 11 W CFL is comparable with a 60 W
incandescent bulb
Saves up to 80% of energy compared to an incandescent
bulb
Greatest switch cycle stability
Best reliability
Easy to install by a E27 or bayonet socket
Compact and robust product design
Electronic protection functions
Reverse polarity protection
Certificates
Approved by the World Bank for China and Sri Lanka
Compliant with European Standards (CE)
Developed in Germany
Manufactured according to ISO 9001 and ISO 14001
[5 W ... 11 W]
Steca PF 166
Solar refrigerator/freezer
The Steca PF 166 is the most efficient DC energy-saving re-
frigerator ever to be developed. It can be used as either a
refrigerator or a freezer.
The Steca PF 166 is fully programmable. The inside tempera-
ture and each of the other configuration values can be set by
the user. It is therefore perfectly suited for all DC applications
including even the refrigeration of medicines in hospitals.
Thanks to the latest A
++
energy efficiency class, together with
optimal electronic control and an RPM control of the com-
pressor, it is possible to ensure that the energy is used extre-
mely efficiently. This leads to significant cost reductions.
This product stands out for its user-friendliness, thanks to a
large digital display with setting options, the highest stan-
dards of quality and reliability and a long service life. The re-
frigerator or freezer is easy to clean as it has a sealing plug on
the bottom for draining water. This maintenance-free appli-
ance can work with an input voltage of either 12 V or 24 V.
