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 EK4036S fix mount 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. Products are tested to full on/off lifecycles under tungsten, magnetic and electronic ballast/left driver loads. Testing is done per NEMA 410 to ensure compatibility with today's array of electronic ballasts and LED drivers. The Intermatic brand assures you of peace of mind and trouble-free implementation. It has enhanced surge protection with 255J and 510J move components. It meets or exceeds ANSI C136.10/C136.24 and UL/CSA requirements. 105-305 VAC, 1000W tungsten, 1800 VA ballast, 6 AMP electronic ballast, instant on - 2-5 second delay off, light level: 1.2-3 fc on; 2-5 fc off.

First ordered an EK4021C based on Amazon write up. It didn't work. Called Intermatic support, they said I needed EK4036S since my lights were LED. OK. It's more expensive, but I want my lights to turn off during the day. Hooked the new EK4036S up per diagram: white to neutral, black to line, and red to load (the lights). I have a volt meter, so I know the line from the load. Lights never turn off. 300 lumen flashlight directly shining on the photocell for 15 minutes, ambient room light, indirect sunlight ... nothing opens the switch. Maybe it works on the sunny side of the planet Mercury. If the seller sends a replacement, I will try again, but I'm done after more than $40 for two non-working Intermatic photocells.

Replaced a dusk to dawn light assembly for our church marquee. Coupled the control with a 30 in. LED light which replaced a burned out fluorescent fixture. THAT burned out because someone thought the old photocontrol eye should be painted along with the rest of the sign. The new system is very quick and should last well past my funeral there. (As long as nobody elects to paint over the eye.)

Works as it should. Went thru several cheaper versions that did not last. Just make sure the wires are pointing down or water will find its way in

I have a Well Water purification system that used an ALR AA-105 sensor (similar to this model) to detect if the UV light was on or not, and if not fire a buzzer. Its 20 years old and I guess the portal is a little dirty inside and the AA-105 would not fire - so the buzzer was on all the time and I had to disconnect it.Voilá - the EK4036S works like a charm - alarm now functional again! In addition, the AA-105 even when working can take 2 minutes to switch off, meaning at best I'd have several minutes of buzzing on any power cycle. This unit switches off (detects the light) in just a few seconds. Fantastic!

Finally, a photocell that doesn't turn lights on too early/off too late. This sensor uses an electronic sensor/board.Traditional photocells are "photothermal" using a photo in series with a small internal heater. A bimetal strip makes/breaks the load.This photocell is WAY more sensitive than tradional designs. It doesn't switch on until daylight is under 5w per square meter. Traditional photocells we're turning on the lights at 200 watts per square meter. On some cloudy days the traditional photocells never turned the light off.Awesome product, highly recommend.

New construction installed in soffits to control accent lighting. Lots of chattering at dawn/dusk. I might have to switch to timers since this is the second brand I have tried.

The Intermatic EK4036S was used to replace a Tork 2001 photocell (after modifying the existing outdoor box/cover installation). While the Tork was reliable and installed only 2 years ago, it would always activate earlier than necessary at dusk and stay on later than required at dawn, meaning almost one hour of wasted energy at each sunset and sunrise. Although the Intermatic is somewhat pricey, it does not have this drawback and operates as expected thereby saving energy. Instead of purchasing a cheap photocell, do yourself a favor and purchase this Intermatic EK4036S (or any of their other EK Series Select Grade Electronic Photo Controls) that will pay for itself in a short period of time. Highly recommended.

I set out to build my own dust collection drum level sensor since commercially manufacturer devices can be pricey. I used this sensor, a DPDT relay and a contactor to do the job. As for this component, it has no delay when darkness is detected and 5 seconds of delay when light returns to the surface of the sensor. This amount of hysteresis seems to work great for my target application. I used a fairly tall LED candelabra-style bulb so that when it gets covered with dust the photo control will immediately cause a chain reaction that ultimately disconnects the power to my blower motor - the circuitry also lights a red light to indicate a full bin. I'm sure this sensor would work great to turn on and off lights automatically as well. I've only had it in service for a handful of days. I drilled a hole in the lid of my drum, inserted the sensor and screwed on the retaining ring. The gasket does a good job preventing any air leaks through the hole.
