Practical as in not super bright, I'd have to go with my old 4Sevens Quark Pro 2A. Goes up to about 250 lumens, but has a sub lumen .2 lumen low, a 5 lumen low, a 20+ lumen medium, an 80+ lumen high, and the 250 lumen turbo. It also takes alkaline, NiMH, and lithium AA batteries.
Practical as in covering all my bases for brightness, I'd go with the Nitecore E4K. Brightness settings are 2 lumens (700 hours, nightlight and reading light), 50 lumens (general hiking light), 320 lumens (security and route finding light), 1050 lumens (running and bike riding light), and 4400 lumens (signaling light). It's waterproof and battery is USB-C rechargeable for car and solar charging on the go. With a floodlight like this, higher brightness settings aren't as blindingly bright and are useful for lighting up a larger area for multiple people.
