LED and fluorescent diagnostics
"Fixed our kitchen under-cabinet lights that were dimming every time the microwave ran. Proper circuit diagnosis and solution."
"Commercial LED retrofit for our office. Professional, on-time, and significant energy savings as promised."
"Installed outdoor landscape lighting that has survived Cos Cob rains perfectly. Excellent work."
Yes. We confirm they're rated for the location and circuit before installing. If something's off — wrong wattage or missing certification — we'll let you know before opening the box.
Most older dimmers were built for incandescent loads. LEDs draw differently. The dimmer needs to be replaced with an LED-compatible one, which is usually a 20-minute fix in Cos Cob.
Yes. We're set up for both single-fixture commercial repairs and full retrofits across Cos Cob, including out-of-hours scheduling.
For commercial spaces in Cos Cob, yes. We map current consumption, project savings from LED conversion, and provide a written report.
Often, yes — but only after we've verified the joist spacing and insulation type. Some older homes in Cos Cob need different cans than the standard residential models.
Lighting decisions are easier when someone has done the load math first. Speak with a licensed Grant's electrician today.
