Indoor • Outdoor • LED • Recessed • Landscape • Smart Lighting
It usually starts the same way. Someone replaces a fixture themselves, the new one flickers, the old one's already in the trash, and now the dining room has been dim for three weekends in a row. Or the recessed lights in the hallway never quite worked right since the renovation, and the contractor stopped returning calls.
That's the moment most Cupertino homeowners find Union Electrical Service. Not for the dramatic stuff — for the lighting that should just work and doesn't.
We install, repair, replace, and upgrade interior and exterior lighting throughout Cupertino, CA. Single fixtures, full-room overhauls, smart lighting, landscape, commercial, emergency. The job ends when the room actually looks the way you wanted it to.
Chandeliers, pendants, sconces and more. We verify wiring, box ratings, and dimmer compatibility for safe, professional installs.
Driveway, pathway, uplighting, and soffit lighting with weatherproof installations and proper controls.
Professional recessed lighting with proper layout, IC-rated housings, and clean installation in finished ceilings.
LED retrofits, full fixture replacements, and compatible dimmer upgrades for maximum efficiency and performance.
A lighting visit goes faster when the electrician doesn't have to leave for parts mid-job. Our trucks carry common residential dimmers across major brands and protocols, LED retrofits in standard sizes and color temperatures, wire nuts and various junction boxes including fan-rated and fixture-rated, fish tape, voltage testers, circuit analyzers, and thermal cameras, outdoor-rated connectors, conduit, and weatherproof covers, and common bulb types — though we always confirm what you have first.
This isn't an exhaustive list. It's the practical reason most lighting jobs we book in Cupertino get done in a single visit.
We avoid pretending lighting work has fixed pricing — it doesn't, and any company that quotes flat rates over the phone is either undercharging until they see the job or building padding into the quote to protect themselves.
That said, here's a realistic frame for Cupertino, CA homeowners:
We give you the number before we start. If something changes during the job, we stop and tell you. No mid-project surprises.
Cupertino has a wide range of housing — older homes with plaster ceilings that don't tolerate aggressive cutting, mid-century properties with original aluminum or knob-and-tube remnants behind drywall, and newer builds where lighting was installed by the lowest bidder.
That mix means a "simple" lighting job sometimes isn't. We've seen recessed light installs reveal undersized circuits in finished basements. We've seen chandeliers replaced into boxes never rated for the weight. We don't pretend these issues are rare; we just plan for them and tell you when we find one.
Walk into almost any home where someone has retrofitted LED bulbs into older fixtures, and you'll see the same problem: flickering. Or buzzing...
The cause is almost never the bulb. It's the dimmer.
The fix is straightforward: replace the dimmer with one rated for LED loads...
If your lighting is misbehaving and you've already changed the bulbs twice, the problem is upstream. The dimmer is the place to start.
Yes, in almost all cases. We confirm the fixture meets safety standards, that the box and wiring can support it, and that any included controls are compatible with your existing system.
Most often, the dimmer is incompatible with LED loads. Replacing the dimmer with an LED-compatible model fixes the issue ninety percent of the time.
We install the wiring and physical fixtures for smart lighting. For platform setup — Lutron, Hue, Z-Wave — we handle the basics.
Less than most people expect. We make precise cuts, work from the ceiling side without opening walls, and clean up before leaving.
Yes. Workmanship is guaranteed. Manufacturer warranties on fixtures and bulbs are passed through to you.
You don't need to know exactly what you want. Most of our best lighting jobs in Cupertino, CA start with a homeowner who has a vague sense of "this room feels wrong".
