When I wrote the article on installing a dusk to dawn photo cell to control exterior lighting, I had no idea that is would be such a popular project.  Not only from the feedback that I have received from all of you, but from knowing that such a simple install can have long term payback both in energy savings and in convenience factor.   I installed my dusk to dawn sensor in April of 2008, and I have not had to touch the switch or change a bulb in the past 9 months.  Better yet, the simple photocell gently turns on the bulb at dusk, and off at dawn. 

I have however, received several requests for an alternative source to the Home Depot photocell that I referenced in the original article, “Installing Dusk to Dawn Photocell in Exterior Lighting to Save Power.“  Whether for availability reasons at your local home center, the sporadic reports that this photocell was prone to failure, or the desire to control larger amp loads, I have done some looking and would like to offer up a couple more options to order photocells that can be wired into existing lighting. I’m going to order some up and install them in my detached garage lights and I keep you posted on their performance.  The two Lumatrol options are Amazon affiliates.  Proceeds to support the site.  The Intermatic options are from a storefront that I’ve never used.   Do your own due diligence before you order and take all the normal online ordering precautions.
