I hope I'm not to far off posting this question on this forum. Some years ago (10) we purchased 4 or 5 simple photovoltaic light switches ( I think they were made by First Alert). We're down to two functioning now, and I cannot find these or anything near to them anywhere (that I've looked!). They were simple plug in the wall then plug your fixutre in and it cycled with day. My wife and I swear First Alert took these off the market because they worked all to well. Now all we see is digital timers etc etc. Anybody have any leads and these simple devices?
I have not seen anything like that. I have see outside style porch lights that have this feature though. Maybe they figured there's more profit to be made in selling you an entire fixture.
Does this have any desirable hysteresis? Their K4123C control cycles 1200 watts of HIDs with a 2-minute period with about 6 footcandles of daylight, esp if some of the light controlled reflects back into the sensor. I'm thinking of adding a 1K resistor in series with the white wire and 39K from there to the red wire to stop the cycling, which wears out the HIDs.
If you don't have your heart set on a photocell, you can also find an astronomic digital timer to do the job. You set the time and what part of the country you are in (there are different zones according to the amount of sunlight during the day). Then forget about it.
I have one and every few years I have to change the battery and reset the clock, in case it drifts. Other then that, no maintenance or attention is required. See the link below.
