Do these need sunlight to work or does light from light bulbs work?

Any source of heat is fine.. I have it in my car so sunlight is good enough

The dancing flowers work well in a sunny window. I have not tried them in artificial light.

It doesn't work by "heat"; it works from "light" - one is much different than the other. Any BRIGHT source of light and you will be fine. The movement amount is directly related to the amount of LIGHT that is impinging on the solar cell (look up how solar cells work on the net). Fact of the matter is, "heat" is the LAST thing one wants or needs in the operation of any semiconductor.

Yes, they use regular light bulbs. I used the power efficiency. Hummingbird's love the yellow ones.

I see your point. You think the solar panel on the light should be sufficient to make these work without batteries, but that's not how it works. These lights have a small solar panel that is attached to the batteries and which charge the batteries to make them work. As opposed to regular batteries which will die within a few days, the solar panel charges and recharges these batteries to make them last a year or two.

Yes, you can control the Iight from an indoor switch, and the fixture has a sensor that yurns the light off when it is in the daylight. It does not need the sun to work, though.

The batteries are already in the light. Just place the light where it will get direct sunlight for 3 - 4 days, after which you can turn on the light in the proper mode that suits you. These lights need at least 10 hrs of sunlight a day.

Thank you so much! It really help me! Just one more thing, are daylight lights?

My experience is that these bulbs only detect movement not light . They do come on during the day if the garage is dark.

The ones I bought are 110v and work great. They are being used in outdoor lighting fixtures that are controlled by a timer. Turns out they do attract bugs, so different bulbs with a different color spectrum of light might be better for outdoors. Otherwise, no complaints and my electricity consumption has been cut from 240 watts for 4 hours a night to 24 watts for four hours a night, sweet. Good luck.

Sunlight is needed but if your porch receives sunlight for some part of the day, it should work well. You may need to move it to a new location if your porch is too dark.

I put them in the dark for three days then put in light. don't need direct sunlight. Have had good luck growing them.

No need it uses light. Just put it near light. Thats all. even in daylight near a window is ok, then you dont need a lamp.

In full sun they will stay lit all night. They are not terribly bright- maybe a 3-4 ft circle of light. The equivalent of a 25 watt bulb?

You need several hours of sunlight, probably a continuous cycle of sunlight during several days. It will burn weakly but goes out after a few hours if the sun has not recharged them totally. Other than that I like the lights, the light produced when fully charged and being able to place where I want light.

THe lights are OK. I tend to set up near my big window, so I like to use the indirect sunlight instead of the lights.

I would use 100W light bulbs at the least if no other light source is available. Also, the light you use must NOT be of the flourescent type. You only really need the required light around the Chrony ;^)

Also luminosity is still pretty weak with solar energy. The alternative is to use LED lights. I am pretty satisfied with a 3 heads lamp post I purchased a while ago at Costco. It is very bright and consumes very little electricity. However, the drawback is that you have to run electrical wires.

Yes, it works very well without direct sunlight. You will find that even on an overcast day, the indirect light is picked up by the solar panel and it activates the fan.
