National Efficiency Supply

Don't have the in-house expertise to properly design your lighting retrofit?  NES will provide you with utility-approved savings calculation, photometric layouts, and a bill of materials.

NES knows that the flow of materials can make or break a job.  We can receive materials at our warehouse and job-pack skids for delivery on-demand to your work site.

After your project is done, we'll still be here.  We will make sure that you have realized all utility incentives, and will manage any warranty issues that arise.

​​NES offers full lighting audit services, which can be utilized by ESCOs and end-users.  A  survey of a facility's existing system ensures the right LED fixtures and lamps are specified.
