I prefer the battery-powered lights. One of the most remarkable inventions is the Crush Light Chroma by Goal Zero. It is powered with solar or USB. You can attach them to nearly everything and everywhere. Awesome product.
We bought some rechargeable mini lanterns that are also bug zappers from Costco. Did not expect much out of them, but surprisingly the seem to put out a decent light pattern, last quite a while and do actually kill a few mosquitoes. We hang the three of them off the awning. We have also been using the Goal Zero Crush Light Chroma, its a great tent light, and love that dims.
