I've been using mine for 3 years now. It's foolproof. Tricky to program, but worth the effort Iand patience). Adjusts sunrise/sunset for each day of the year automatically, can work with a transformer (and dimmer.) Versatile: you can use sunset ON, a specified time OFF, sunset ON, sunrise OFF as you wish. Adjusts for daylight saving as well.
This gadget relieved me from the chore of re-setting my walk light time several times per year...and the cost of having them go on while it's still light.. Great break-through

High Quality Product
I've been using Intermatic products for years and the ST01C does not disappoint. It is adapted for use with the new energy smart bulbs and Iinstalled all new timers when I switched to the new bulbs. Intermatic has also upgraded the features on this model. It is highly programmable with options for seasonal time changes where you don't have to do a thing but choose the DST mode. The ST01C is well built and engineered. I wouldn't hesitate to purchase this product again.

Works great! I can keep people guessing when I'm home and awake. I use this on my garage and sidewalk lights. We have had a problem with young adults running around the neighborhood at night. They certainly don't hang around my house anymore!

I need operation instructions for the wall switch timer (intermatic EJ500C). Could you email me one? Thank you David
Hi David. Here is a link to a PDF file for those instructions. http://edmullen.net/manuals/Intermatic_in-wall_timer_EJ500C.pdf KMR
What does the spec ' For single pole and three way applications up to 100 ft.' mean? I have lights about 400 feet away from where this controller will be located. Will this work?
The Intermatic digital wall timer has a distance limit of 100ft. Distances over 100ft may not work as well as it is designed to. This applies primarily to 3-way applications.
Can the Intermatic EJ500C switch or the ST01 be used with compact flourescent light bulbs
The Intermatic EJ500C will control only Incandescent Lighting, where as the ST01 will be able to control your Flourescent lighting.
