Lighting is usually the largest controllable electrical load in a commercial building and the easiest one to cut. APEX Electric designs and installs LED retrofits for offices, warehouses, retail and parking areas — improving light levels while reducing consumption, and handling the utility rebate paperwork that pays for part of it.
A one-for-one lamp swap frequently over- or under-lights the space, and in a warehouse the difference shows up as a safety complaint. We work from the actual footcandle targets for the task — warehouse aisles, office desks, a parking lot's perimeter — and lay the fixtures out to hit them.
The result is usually fewer fixtures than the space had before, at better and more even light levels.
LEDs cut the wattage; controls cut the hours. Occupancy sensing in low-traffic areas, daylight harvesting near glazing, and scheduling on exterior lighting routinely add a further meaningful reduction on top of the fixture change.
Many current commercial energy codes require these controls on a lighting alteration anyway, so it is worth designing them in from the start rather than adding them after an inspection.
Ameren Missouri offers prescriptive and custom incentives for commercial lighting upgrades, but the applications have to be filed before the work is complete and require specific fixture documentation.
We handle that filing as part of the project and give you a payback analysis based on your actual rate and operating hours — not a generic marketing figure.

It depends on your operating hours, your rate and the fixtures being replaced. High-hour spaces like warehouses and parking lots pay back fastest. We model it against your actual usage before you commit.
Yes. We prepare and file the Ameren Missouri paperwork and supply the fixture documentation the program requires. Applications generally have to be submitted before the work is finished.
Almost always. We phase the work area by area, and where a space cannot be disrupted at all we work after hours.
Yes. We test, repair and document emergency and exit lighting to the schedule your fire marshal and insurer expect.
