I think the most common one is Intermatic. It took about 10 minutes to set mine up. You just have to put another event turning your lights "on" at the end of the week or it won't reset.

The other one I have had really good luck with is the X10 automation system. It requires a computer, but also works.

Check my IC webpage in my signature for more info.

Just buy a Cycle timer. Set any on time and any off time. That way your not tied to weird numbers like 6:40 just so it will repete on the 7th day.

Wow, CBB dropped by.

:respect:

The National Garden Wholesale doesn't suggest Intermatics for anything over 600w though. I don't know why, but I would trust what they say.
