>>2781487Just get some chinesium lights and put the good cells in.
The thing is most 18650 lights are rechargeable. And they take awhile to run through good cells, so you can always recharge them after some use while they’re still in the light. It’s not like “I have a 5 year supply of AAs, what lights use those?”
I like the tacticool zooming lights that were sold under some as seen on TV Bell & Howell Taclite brand but are all over Amazon like 2 for $10. They come with 3x AAAs inside, but the 2pk I got came with little plastic sleeves for 18650s. Leave em all over the place with quality Samsung or LG 18650s, they’re brighter with the lithium cells than the 3x AAA holder, and they’re great to loan out to people and grab whenever you need the nearest light.
