Smart home and office automation is transforming how we interact with our environments, especially in tech-forward communities like Naperville, IL. Whether you’re upgrading your workspace or enhancing your home with intelligent lighting, climate control, and security systems, seamless integration is key. But what happens when your LED lights start blinking unexpectedly after installing a Lutron Caseta Original Smart Switch in a three-way configuration?
This issue is more common than you might think—and fortunately, there’s a simple fix.
The Problem: LED Light Blinking in a Three-Way Setup

During a recent office automation project in Naperville, a saw that their LED light was blinking intermittently after installing a Lutron Caseta Smart Switch. The setup involved a three-way switch configuration, which is typical in both residential and commercial environments.
This blinking is usually caused by the low wattage of LED bulbs, which can confuse the smart switch’s internal electronics. The switch may not detect enough load to remain stable, resulting in flickering or blinking lights.
The Solution: LUT-MLC Capacitor
The fix? LUT-MLC, a small capacitor designed by Lutron to stabilize the load on the circuit.
What is LUT-MLC?
The LUT-MLC (Minimum Load Capacitor) is a device that connects across the load terminals of the switch. It helps ensure the switch detects a consistent load, preventing the blinking issue with low-wattage LEDs.
Installation Tips:
- Turn off power at the breaker before installation.
- Connect the LUT-MLC across the load wires at the light fixture or switch box.
- Restore power and test the switch.
This simple addition can make a world of difference in your smart lighting setup.
