- Outdoor Light Timer with Dusk to Dawn Sensor, Weatherproof Dual Grounded Outlets for Christmas Decorations, 15A 1/2HP ETL Listed(2 Pack)

After trying on my Christmas lights with no luck, i read the fine print that these do not function when connected to extension cords. I have main runs out to my yard and wanted these for some items and others to come on and off with mechanical timers. These do work when connected directly to the outlet. I hated to pull a star because it didn't meet my needs, just wish i knew the extension cord limitation.

I bought these to control halloween and christmas decorations. Technically, these are just an overglorified clock turning on/off a switch so they are not as energy efficient as one of those modern digital timers but I trust these to work and last a long time as I grew up with grandparents that would use the original version of these devices to control lamps while they would go out of town on vacation. They work well and since they have two outlets they are easy to use.

I've been through several sets of these with the overwhelming majority being defective. The units will turn the lights on, but will not shut them off regardless of which setting you use. I noticed that the only ones that work have solid clicks between settings in the dial. If the clicks are soft, the timer is guaranteed to not work. BN Link has good indoor plugs, remotes and timers, but these outdoor timers are as bad as I have seen from any manufacturer. With a failure rate of greater than 70%, I will never buy these again.

Easy to set up and works like a charm. We use these for our outdoor garden lights as well as string lights we have hung in our backyard. I love that you can literally set and forget with these. They are especially handy for when we go on vacation so that the lights still go on at dusk and off in the morning, making it not as obvious that we are gone.

I wanted to use this one to control Christmas lights at our front door. The dusk to dawn makes it easy for on/off. At first it did not turn on as expected at night. Apparently the front door light out side was enough to keep it in day time mode, ie off. I put a finger over the sensor and 10-20 secs later it turned on. So I ended up tugging the sensor behind a plant and that took the direct light and now it turns on and off as expected. I have only had it for a week and do not know how it handles the Minnesota winter.

This product helped me a lot. With the timer function, I can turn on the lights in my backyard as soon as it gets dark, and I can see my garden at night for as long as I want.

Timers work great for Christmas lights. The delay is perfect
