Lutron Maestro Countdown Timer Switch for Fans and Lights - Energy

Our review of the Lutron Maestro Countdown Timer finds it best suited for homeowners who want a simple, reliable way to prevent lights or exhaust fans from being left on in low-traffic spaces. The single biggest reason to buy is the straightforward countdown control that combines a large tap switch with a rocker to choose from preset timeouts, so the device saves energy without complex programming. Installation is not elaborate if a neutral wire is present, and the unit works with modern LED lighting and high-efficiency fans, making it a practical upgrade for bathrooms, closets, basements, and garages.

Key Features

• Countdown control: The large tap switch starts the timer instantly and a one-minute warning LED alerts users before turn-off so lights or fans are not cut off unexpectedly.
• Adjustable timeout: The side rocker lets you select fixed time options from 5 to 60 minutes, giving predictable control without programming.
• Compatibility with LEDs: Rated to handle up to 150 watts of LED lighting and a variety of bulb types, the switch works with most modern low-watt fixtures.
• Fan support: Designed to control 3A high-efficiency exhaust fans, making it suitable for bathroom ventilation to reduce run time and energy use.
• Multi-location option: Can be used in multi-location setups when paired with a Maestro accessory switch, allowing flexible control of the same circuit.

Who It's For

Homeowners with low-traffic rooms who want a simple hardwired way to limit run time on lights and fans will appreciate this switch. It is especially useful in bathrooms where exhaust fans can be left on and in closets, attics, basements, and garages where people forget to turn lights off. Installers and DIYers who are comfortable working with household wiring will find the swap straightforward and quick.

Buyers who do not have a neutral wire available at the switch location should look elsewhere or plan for additional wiring, since the unit requires a neutral. Also, those seeking smart-home integration or remote app control will need a different product, because this is a manual countdown timer rather than a networked device.
