Your cart is empty.J.LUMI YCA1030 Through-hole mount dusk-to-dawn photo control ideal for residential outside post light control and able to be mounted into standard outlet box, post lamp pole and wall pack fixtures. Thermal sensor eliminates the load temporarily switching off due to car headlights, lightning or another temporary light source. Locking nut and washer gasket help keep moisture from penetrating photo control device. Requires a minimum 5/8 In. through-hole for proper mounting and wires should mount down when properly installed.

I needed a replacement switch for some outside lights. The old one had become so clouded that the lights stayed on 24 hours. After turning off the power at the circuit box the only challenge was opening the electrical box on the side of the house. Reading the instructions and looking carefully at the existing wires in the box are important. This isn't as simple as a single-pole switch but it's really simple when you know what to expect. Hooked up the photocell, turned on the power, and the lights came on and then switched off in about two minutes as it sensed the daylight. It's been a couple of months and it is working fine. I bought the two-pack so I'd have a spare but I don't know if or when I might need it.

Most photocells, Amazon, retail, and otherwise, use Cadmium-Sulfide based LDRs (light dependent resistor) which have been around for decades. These are easily identifiable but the brown/red squiggly object inside the lens. Unfortunately over time these are prone to drift, meaning their light sensitivity weakens to the point where the light stays on longer than it should and eventually fails altogether.I specifically purchased these because they use phototransistor/photodiode technology which is not only more precise, but is not subject to the drifting issues like CdS sensors. Internally these use modern electronics and relays which are more reliable to control the load as opposed to a thermal bimetal switch which is the older way of switching loads on and off.This was installed in the pole light in my front yard. The old one was a CdS and bimetal switch variant which came on way too early, so it was due for replacement. This was identical physically and wiring wise. Upon first power up, there is about a 10-11s delay with the light switched on. After this, the sensor has about a 3s delay after “dark†to turn on, and about a 5-6s delay after “light†to turn off. Long enough to prevent false triggering, and short enough to not be waiting forever.It is also UL listed so this is safe to use. Not all off brand products carry this, so I was happy to see it.

Ease of installation depends upon if one is simply replacing a sensor that is essentially identical or installing the sensor in an enclosure that was not originally a photo sensor controlled fixture. The sensor eye is a threaded 5/8" plastic extension from the sensor body; this exceeds the 1/2" usually contained in most drill sets. Therefore, one must drill a 1/2" hole in the fixture and either enlarge it with a circular file or buy either a 5/8" drill or a step drill. In addition, the location of the sensor is important. If it is located where it is exposed to the fixture's light itself, it will cycle on and off every few seconds after dusk; this is normal function of the sensor. The solution is to mask the sensor from the fixture's bulbs leaving enough exposure of the sensor to an area where daylight would turn off the sensor. This can be done by constructions a small metal enclosure from thin sheet metal or by some other means. For those who have not faced this problem, a short note in the package would prevent one from concluding that the product was defective if it cycled on & off after dusk

I had a little problem installing because the wires were not stripped quite as far as I needed. Of course that was easily remedied. The instructions were essential, and when I followed them, they were great. Good price too.

I needed a light to help illuminate part of a pathway in front of my well house, and I didn't want to have to turn it on and off. Lowe's and Home Depot had sensors for...well, more for one than I paid for the two here. The sensor was a little too awkward to fit in the round electrical mount box for the light, but I picked up a cheap plastic box to add to the top and tah-dah!On the first day I assembled as much as I could inside while it was raining out.On the second day, I went out and mounted and wired everything and said, "let there be light"... and there was none. The directions in the box were a little confusing to figure out (the ones on the product page photos are perfect and what should've been in the packaging), but after a more detailed look, I got it wired correctly. I held my hand over the sensor, and again I said, "let there be light," and so there was. When dusk rolled around, it came on just like it should.Then, on the third day, I rested.

I installed this sensor eight months ago in our lamp post. It was fine for that time, until today. Now the light doesn't turn off, which seems to be the fail mode for this type of unit. It was installed correctly, with the wires (penetrations) pointed down.Reliable units for this type of sensor don't seem to exist anymore. Our original unit lasted for decades. Anything I install now fails in a matter of months. For now, I'm going to use the screw in type of light sensor that just mounts to the light socket. That type of sensor has been reliable and when it fails, it's easy to replace.

Works great with my garage LED bulbs. Not one issue. Great product.

The sensor I replaced was 15 years old, this is an exact match so I hope to get another 15 years out of it. Easy to install and worked immediately.
