Leviton DT130-1LW Countdown Timer Switch
The Leviton DT130-1LW is a compact, single-pole countdown timer designed for bathroom fans and household lights. It offers four preset durations: 5, 10, 15, and 30 minutes. The unit is engineered to fit shallow wallboxes, simplifying replacement of existing switches. It supports up to 600W LED/CFL loads and 1800W incandescent/halogen, with a ½ HP/9.8 Amp rating for fan motors. A green ground sleeve allows wiring with or without a neutral in the wallbox, but a ground connection is required for installation.
Leviton DT160-1LW Countdown Timer Switch
The Leviton DT160-1LW expands the DT line with 10-, 20-, and 30-minute presets and 60-minute options in some configurations, all within the same single-pole form factor. It shares the same ground-flex wiring approach for installations without a neutral conductor and remains compatible with LEDs, CFLs, and various motor loads. Like its sibling, it fits into shallow boxes and requires a grounded connection for safe operation.
ENERLITES Countdown Timer Switch (1–30 Min)
ENERLITES offers a neutral-wired option that provides six preset times from 1 to 30 minutes. This model is UL Listed and supports turning off ventilation, lighting, and heating devices after the set interval, making it suitable for bathrooms and other small spaces. It’s designed to replace standard wall switches and is compatible with LED and CFL loads, though a neutral wire is required for operation.

This two-pack from ENERLITES includes six preset options: 1, 5, 10, 15, 20, or 30 minutes, with a blue LED indicator and a manual override. It replaces standard wall switches and is ideal for bathrooms, laundry rooms, or any space where ventilation or lighting requires timed control. A neutral wire is required, and Blue LED helps you visually confirm active settings.
ENERLITES 4-Hour Countdown Timer (2 Pack)
The 4-Hour ENERLITES timer offers presets of 5, 10, 30, and 60 minutes plus 2 and 4 hours. This model is designed for wall-switch replacement and includes a neutral wire requirement. It’s positioned for durable use in bathrooms and utility areas where extended ventilation timing is beneficial, with a blue LED indicator signaling active status and a straightforward reset option.
Buying Guide: Key Purchase Considerations
When selecting a timer for a bathroom fan, several factors influence performance and compatibility. First, determine whether your circuit requires a neutral wire. Many modern timer switches operate without a neutral by using ground as a return path, but if a neutral is present, a neutral-reliant model can be more stable and compatible with LED and CFL loads.
Second, review load ratings and the type of fan or light you’re controlling. Most timers support common bathroom fans and lighting loads, but high-wattage motors or combination loads may require models with higher amperage or HP ratings. If you have a ceiling fan with a motor, confirm the timer’s motor amperage and documentation to ensure safe operation.
Third, assess the installation space. Some timers are designed for shallow wallboxes, while others may require more depth. If you’re replacing an existing switch in a multi-gang box, ensure the device fits the existing opening and plate style, especially if you use decorator plates or multi-location setups.
Fourth, consider user interface and presets. Four preset timers are common and suitable for typical bathroom routines. Some models offer additional presets or repeat modes, which can be helpful for daily routines or shared bathrooms. Push-button versus toggle styles affect ease of use and accessibility in dim or cramped spaces.
Finally, check energy-saving benefits and LED indicators. Timers with LED indicators provide quick confirmation of active timing and can help prevent leaving a room with a timer still running. For households prioritizing energy efficiency, compare models by their standby compatibility, ease of reset, and reliability across loads such as LED lighting and various fan speeds.
