Need Battery operated LED light advice

Hello everyone

I am new to lighting completely, but I have been researching a lot.

It’s still all a lot of Mumbo jumbo to me right now regarding watts and colors...

I am looking for a supplemental grow light for winter that would work for vegetative and flowering growth. I want to run experiments on growing 1-2 plants outdoors during off peak season using supplemental lighting. I have a little greenhouse and I want to find a battery operated light that I can turn on when the sun goes down.

Or even a plugged light, preferably a battery operated light if there is one that works for growing plants.

Can anyone recommend a light?

I appreciate any advice on this matter

Thanks
Tessa

i wanna see how this works out...

Any battery operated light should work as long as its at least about ten watts per m. If you can, add a bit of 660 nm meter to the mix, this is the actual wavelength that wakes plants up and keeps them away. im interested in how you work out the battery part; with the right leds you should be able to just use the battery almost straight into the led, or with some small current regulating driver. But i wouldnt quite know how. Maybe LDDs??

lights is going to be very underpowered for flower unless you have a very pro and expensive battery setup.

I build portable lithium banks and they aren't really cheap, $150 for every 250w/hr in batteries alone, that's $2000 for 250w over 8 hours and you still need an inverter, charger and battery monitoring system, Which is another $350+ easy.

Id run an extension cord or generator if you can get away with it.

Yes I think the extension cord is going to be the best route.

What about a light just a light can someone recommend a light that I can put outside in my greenhouse?

High pressure sodium or an led panel.

Thanks
