(for the picture only, I have no idea about the site)
I got these for my mother, and put them all over the place (nightstand, side table, patio, bathroom) just in case there is a blackout. :roll: The ones I bought used 4 AA batteries each. HD/Lowes/Walmart/Target - all will probably have them in stock.
