Lighting is the fastest way to change how a room feels, and the easiest thing to get wrong. APEX Electric plans and installs residential lighting across St. Charles County — recessed cans laid out to the room rather than a grid, under-cabinet task lighting, landscape and security lighting, and fixture swaps that land level the first time.
Evenly spaced cans in a grid light a floor, not a room. We lay out recessed lighting around what you actually use — the counter, the reading chair, the artwork — and keep the fixtures off the ceiling's centerline where that reads better.
Colour temperature matters as much as placement. We standardise on a consistent Kelvin value across a floor so one room does not read blue next to another, and we specify high-CRI lamps in kitchens and bathrooms where colour rendering shows.
Most complaints about LED dimming come from a mismatch between the driver and the dimmer, not from the LEDs themselves. Buzzing, a dead zone at the bottom of the range, and flicker are all avoidable with a compatible pairing.
We specify the dimmer against the fixture's driver, and we test the full range before we leave.
A ceiling fan needs a listed fan-rated box — a standard lighting box is not designed to carry a moving load, and this is one of the most common defects we find in homes where a previous owner did the work themselves.
Heavy chandeliers, sloped ceilings, two-storey foyers and outdoor-rated locations each have their own requirements. We handle the access and the support, not just the wiring.
Available across O'Fallon, St. Charles, St. Peters, Wentzville and the rest of St. Charles County.

It depends on ceiling height, room size and what the room is for, but layout matters more than count. We plan around the tasks and features in the room rather than applying a fixed spacing rule.
In most cases, yes. Canless retrofit LEDs install through a small hole and are designed for exactly this. Where joists, ductwork or insulation get in the way we will tell you before we start.
Almost always an incompatible dimmer. Older leading-edge dimmers were built for incandescent loads. Swapping to an LED-compatible dimmer matched to the fixture's driver resolves it.
Yes. Most smart switch families support three- and four-way configurations with a companion switch. We confirm you have a neutral at the box, since some models require one.
