I have purchased and given away hundreds of flashlights (being 70 years old, I have had lots of time). My favorite single AAA is, without question, is the Surefire Titan Plus. I use it every day, and it is rock solid. The only problem that any of my family have had using 7 is losing it. there are lots of AAAs that are lighter, (we have and use many) but the Titan Plus is bomb proof.
