Good Christmas lighting controller,
By Handyman (Columbus, Ohio) - See all my reviews
This review is from: First Alert Outdoor Digital Dusk-Dawn Countdown Timer with Photocell, 3 Prong Grounded Plug Model # ET321
I bought this a year ago from Walgreen to control my outdoor Christmas lighting. Initially, I was confused with this little thing that has only one push button to set. Finally I figured out by studying the manual carefully and experimented a little with each of settings. Once you know how to set it, it is very easy to use as compare to those that has many buttons.Here is how it works. The push button repeats itself in following sequence (must plug in). F 1 2 3 4 5 6 7 8 9 A d 1. 2. 3. 4. 5. 6. 7. 8. 9. F: timer is off. 1 2 3 4 5 6 7 8 9: from dusk to dawn count down number of hours repeated every day. That's most useful to control outdoor lightings. A: from dusk to dawn count down number of hours which is randomly selected by this timer. Which is usually for indoor use to turn lights on and off for number of hours. The randomly selected hours is a security feature so that lights on (on from dust, but off randomly) time shows no pattern to outsiders. d: just on from dusk and off at dawn. It is also used to control outside lights but just a little wasteful in my opinion. 1. 2. 3. 4. 5. 6. 7. 8. 9.: meaning count down number of hours starts from the time when the button is pushed so that you can have a countdown timer at any time. This unit works very reliably for last Christmas. Now I am taking it out ready for this holiday. One extra note: since the timer has a photocell in it. Make sure you place the timer at a location (especially when used indoor) that can sense the day and night. It does not work in a heavily curtained room!

High Quality and Reliable,

This review is from: First Alert Outdoor Digital Dusk-Dawn Countdown Timer with Photocell, 3 Prong Grounded Plug Model # ET321
I bought this to control my outdoor Christmas lightings. It seems to be made of high quality material and the electrical cord is a great length to fit in my outdoor plugs without having an excess of cord leftover. I am using the unit to turn on at dusk and stay on for 8 hours and then turn off. If is working very reliably. You need to read the instructions to understand how to program the unit.
