Outdoor Wi-Fi light bulb setup Answered
With the social distancing going on right now, I wanted to take a crack at a project that has been rolling around in my head for a while.
Short story is I would like to build a solar charged, battery operated, power supply to run a color changing Wi-Fi light bulb in a lantern housing that would then hang outside on a lamp post.
I will freely admit I have pretty much no idea what I am doing.
I know I need to make sure that the Amp-hour are at least 50% more than what I need. I know there could be a way to use an inverter to get the voltage from DC from the batteries to AC for the light bulb base. And I know there are a lot of numbers and equations that I am unsure of how to use.
And yes, I am aware that there are many different kinds of solar powered garden lamps out there. But none of them are as powerful, nor have the color options, I am interested in .
So here is my idea.
1 - 7-10 watt WiFi color light bulb that screws into a standard E26 socket and runs at 110 volts.
So far I think I have figured out that this bulb would run at 0.0909 amps, or 100 mA.
If I did the math right, that brings me to needing a 6 Ah battery to run it for 24 hour.
My stumbling block is I do not know how to size an inverter to correctly go from the DC of a battery to the AC needed by the bulb. Nor what size of battery I would need to run a 7-10 watt bulb at 110 volts for 24 hours including the additional energy to compensate for the inverter.
I cannot imagine I would need a battery as large as a car battery, but I also have no idea.
Any assistance you could provide would be greatly appreciated.
