Lighting The cost of residential lighting
ranges between 10% to 20%
Solid-sate Lighting of the monthly electric bill.
+ Sensors In Germany today, a typical
expenditure on electricity for
lighting might be 20 euros per
month. In France, because of
lower rates, a typical expenditure
might be 10 euros per month.
By changing all lighting sources
to LED a resident might realize a
savings on electricity of 1-2 euros
per month, or the equivalent
of one extra cup of coffee per
month. This potential savings
is small compared to the cost
of changeover. In addition, the
residential user can rarely benefit
in concrete terms from the
additional functionality offered by
Smart Lighting.

Figure 3: Smart Lighting is a combination of SSL, IT and Human factors On the other hand, Smart Lighting
