Best Way to Automatically Turn Off a Lightbulb After 30 Minutes?

Asked by CuriousNomad84
I've got a walk-in closet with a door-jamb switch that works great for turning the lights on and off. However, I have a cat that likes to nudge the door open, which means the lights sometimes stay on all night. Since there's no regular light switch, I'm looking for a lightbulb or bulb base that can start a timer when turned on and automatically shut off after about 30 minutes. I've done some research but didn't find an easy solution. The space around the door jamb switch is pretty tight, so something like a Shelly relay wouldn't fit. Plus, the light fixture doesn't have constant power, which complicates the idea of a smart relay or bulb. Any suggestions that would keep both my cat and me happy?

Consider getting a Lutron Maestro Countdown Timer Switch. You just turn it on, and it will turn itself off after a set number of minutes. It's perfect for situations like yours where you can't reach the switch easily.

There are smart bulbs that connect to your WiFi. You can control them using an app like Alexa or the bulb maker's app, where you can set routines to turn the light off automatically at certain times. Super convenient and works well in closets!

You might want to try a motion-activated bulb! They typically stay on for a set duration after detecting movement, which could work well for your closet situation. It’ll automatically turn off after a while, saving you from those late-night light dramas.
