Timer with DC input & DC output

lumen aeternum

I can't decipher the contradictory Chinglish on Amazon.
Seems like everything I find has DC input to switch an AC line on & off.

I need to put pre-dawn lighting into the chicken coop to give them 14 hours a day of light.
Plenty of solar cell + battery + light sets to buy, but they don't advertise what voltage they use & have a photocell, which is useless. Maybe something for Recreational Vehicle lighting would be suitable...

I want to use a small tractor battery or high capacity Nimh or Li-ion batteries, charged by a solar panel. Dunno how to get the right output voltage for whatever the LED lights would use.

Suggestions for the entire package welcomed.
