Depreciation on LED Lights

Amortization and costs for a project of LED lighting for parking or parking

Take the case of the case of a typical car park office building, with a large number of seats on three underground floors. The approximate area of the surface is about 3,000 m2. The parking will be a normal use of 24 hours a day and 365 days a year.

Currently the lighting consists almost in its entirety of fluorescent tubes 36W, installed to 3.5 metres. The luminaires have a general appearance badly damaged by the passage of time and the absence of regular maintenance. Light levels taken on plane tool (soil) are normally about 35 LX, insufficient light according to the applicable regulations.

Once an energy audit of lighting, could be detected the following inecidencias:

  1. excessive power consumption. Potential savings of 60%
  2. the light levels, as well as the light distribution, do not conform to the normative framework applicable to the type of activity to develop.

LED lighting

With proper installation of LED tubes we can get:

  • Excellent values of energy efficiency up to 60% on the electricity bill. The removal of ballast and Starter helps to reduce consumption.
  • A better luminance mean drawing more uniform and luminous spaces (Emin/Em), eliminating dark areas, increasing the perception of security.
  • Immediate, flicker on
  • 100% free of toxic substances, such as mercury or lead, and reduction of CO2 emissions

Conclusion and results

With the introduction of a new system of LED lighting from Listofledlights more efficient and functional, you can get reductions of up to 60% power consumption, in addition to adapt installation to the current regulations. User will be valued very positively the improvement in lighting, especially with respect to their sense of security. They were issued approximately 20,000 Kg of CO2 to the atmosphere. The investment pays for itself in months.

There is the possibility of installing LED tubes with presence detector to avoid keeping the lights on when there is no presence in the parking lot, thus saving hours and hours of energy expenditure. Browse sensor radar and detection of presence.
