## Description

Are you installing light fixtures with extended life expectations? Intermatic's electronic photocontrols are designed to match the long life of new LED lighting fixtures with a 10 to 20 year service life expectancy. This allows full realization of both the cost savings and benefits of maintenance-free lighting installations. The EK4536S locking-type electronic photocontrol by Intermatic has been designed, tested and warrantied for long life. It has improved on/off switching with high quality relays and employs electronic components exclusively selected to meet extended life targets.

Review: Quality product - I have purchased this product before and now because it works like it is supposed to. My previous experience with some other photo electric units are that they fail by becoming stuck on the "on" position. Also some other units have activated when there is still a considerable amount of daylight or have a delayed morning shut-off.
Review: Works perfect - This was a great item that replaced my old unit that was staying on all day. Fast shipping and item works line it should.
