I bought this sensor for a home spotlight to be installed under the eaves of the house. The sensor must be installed with the wires up. The instructions say in bold not to do this. On the sales page, he didn't mention this tidbit. I will call the company on Monday to see what options are available. Customer service claims if you install it with the wires up, condensation will form, drip onto the wires, and burn. From the block. I will definitely try it and see how long it lasts. Only 2 stars because they don't post the wire alignment information on the website or on the packaging.
