LED Depreciation in Communities

Costs and amortization for the installation of LED lighting in a community of neighbors

Let us look at the case of a standard community from about 4 floors in height, portal, stairs, halls of counters, a medium garage and access. The parking will be a normal use of 24 hours a day, 365 days a year.

The most of the expenditure in light of the community, is in the consumption that generate them tubes LED from the garage and their accesses. We have calculated about 136 units of fluorescent tubes 36w each. Tubes led from the garage normally do not present a good overall appearance, tend to be impaired by the passage of time and the absence of maintenance. The rest of the lighting of the community is distributed between the portal, plants and accesses. In this example we will use the classic incandescent light bulbs E27 36w installed 3 ceiling 3.

The installation is very simple and quick. All the bulbs spread by the Community (flats, quarters of counters, etc) is replaced by new bulbs LED of new generation. For the replacement of tubes led would have to eliminate ballast and starters (saving their consumption) excelentes values of energy efficiency and una average brightness most bright and uniform. Led tubes are also immediate ignition, flicker.
