smart bulbs?

LOL- some genius asked:

Using in porch lights. Do I need to leave the light switch in on position or off?

or this:

Does this work on 220 volts?

Finally someone asked your question:

Question: will these work for a 3 bulb lamppost? Only 2 at a time light up

Answer: Yes, it can work for a lamppost, but the dusk to dawn lights will influence each other if you place them too close. And at a distance of 1 meter is the best between two bulbs.

Oh, I was trying to turn it into an oscillator... which didn't work. But certainly it seems that a few lights near each other could leave one off.. close enough only one could dominate.

I expect they will. I've even seen a light sensing light confuse itself when too much of its own emitted light is reflected back to its sensor.

$5 each is a bit pricey...

Would three bulbs turn chaotic?

void _-void-_ in the obvious place

Now you've done it. I'm almost tempted to buy three to find out.

If it does, you can be sure it will turn up in an "art installation" very soon...

There, John. Does that answer your question?

I was guessing that the light sensor works when the LEDs are off. If at the AC zero crossing, they might not interfere.

Seems absurdly cheap to me.

You can get a motion-detector bulb for a similar price.

We got a bunch of battery-powered motion-detector+ambient light sensor LED pucks to stick in dark closets, for a few dollars each. That's amazing.
