Our turnkey lighting retrofit process is simple and stress free.
Our process includes everything from providing your project cost and payback, to providing fixture recommendations, installation during off shifts with our experienced lighting installers. We will dispose of your old fixtures and lamps.

We won’t shut off the lights and we’ll install around your production schedule.
Our lighting installation team specializes in lighting retrofit projects for warehouses and manufacturing environments. We work around your schedule, sometimes installing second or third shifts (at no extra cost) to get our work done without interrupting your production. If we need to install over the weekend we understand, because that’s our business.
You may be eligible for a utility rebate.
Some energy companies offer rebates to encourage industrial facilities to do lighting energy retrofit projects.
Contact us and we will let you know what’s available in your area.
If you work multiple shifts, you’ll be surprised at how fast your payback is, even without a rebate.
