Input:
Question: Does it have a time delay to prevent false switching? (example: a flash light shines on the unit for a couple seconds and it switches the light off)
Document: Did not test on ac voltage. Using this sensor to control an outside LED light on an RV. Low price, but works just as it should! This unit could be used to 'slave' a much larger 12v relay for switching high current draw devices. There is no weather seal around the screw for the mounting bracket.
Received within a few days but it is DOA. Hooked up based on instructions found in reviews (which are consistent with an email another reviewer received from the seller). I am using a test light for the load and the test light is working as verified by a direct connect to the 12 volt source. Apparently the majority of reviewers got a working unit - I lost the lottery.
This is a well built unit, compact, and does the job perfectly. It hooks up with no problem, and has been working as good as can be expected. I recomend it to anyone trying to turn On and OFF 12vdc lights under control of the sun.
First it came with no wiring instructions. I got those from the QA posted here. But on two attempts to wire it - nothing happened. Have not had time to try again.
it came on time and was much smaller than I expected, have it mounted inside a south facing window in carport storage area, Its working like a champ.
This 12 volt photoswitch works well in a 12 volt lighting system. I have not yet attempted to include a small 12 volt pump in the circuit but will try that at some time. The only issue i had is that it is not waterproof for use outdoors. Mounting near a window inside appears to be sufficient.
Usually I want things quickly and I suppose I'm spoiled by Amazon Prime, but I don't see between a week or two, or more as being quick. Once you order, the ship estimate from these guys is ridiculously long. Pretty hard not to beat their estimate.Anyway, the item is OK but I think the waiting time has to be factored into a good review if it is &#34;outside the ordinary&#34;.
thanks-Exactly what I wanted to turn on a LED light @ night---wonderful product.thanks.
Easier to installed just use common sense nothing to adjust can add more light on it  and good to go
I use this for a 12 volt night light and it works very well. Very easy to install. Good application for stand alone solar application.
Answer: no
