Here is an excerpt from CSE:
“Good lighting enhances building design, conserves energy and increases productivity, safety, security, personal comfort, sales, attendance and profit. According to several government sources, up to 40% of the total energy used in commercial buildings is used for artificial lighting.
In lighting, one size/type does not fit all. LEDs in particular have gained prominence in lighting design for their energy efficiency, holistic lighting options and operational savings. LED retrofits can save 40% or more energy when compared with traditional light sources such as incandescent, halogen and high-intensity discharge.”
