Buying Guide: Key Considerations
- Timer type: Mechanical vs digital. Mechanical is simple and durable; digital offers more scheduling options and remote control.
- Outlets: Consider how many devices you’ll run. Two outlets allow simultaneous control of lights and pumps or decor.
- Weatherproofing: Look for splash-safe housings and vertical mounting recommendations to minimize water exposure.
- Power rating: Ensure the timer supports the total load (amps and horsepower) of your outdoor lighting setup.
- Sensor vs. manual: Dusk-to-dawn sensors simplify daily use, while simple on/off timers give precise control without sensors.
- Remote control: Some models offer RF remotes for indoor operation; check range if you’ll control from indoors.
