Energy Efficient Lighting Upgrades Reduces Facility Costs

Upgrading your lighting system is a fast and simple way to reduce electric consumption, improve facility appearance & aesthetics and in providing a productive working environment.

Advances in lighting technologies make it economically feasible to retrofit older technologies realizing a payback period between 12 to 36 months often without out-of-pocket expense beyond what is currently paid to utilities. Many local electric utility companies offer commercial lighting rebates to help fund material and installation costs. Database of State Utilities Rebates http://www.dsireusa.org/

 

 

 

Commercial lighting retrofits are a high-return low-risk investment that reduces electric consumption and extends lighting maintenance periods that help to reduce facility maintenance costs. Thanks to new technologies there are energy-efficient alternatives to older lighting systems without sacrificing light levels or quality of light. Below is an expample of a common retrofit option found in many 12 to 15 year old office warehouse facilities.
