That depends on if you need 400 lumens. Unless it has a 20 lumen mode, it's useless around a campsite, it'll blind everyone when you flip it on. There are very few situations in real life where 400 lumens is appropriate. Search and rescue people would be one. Bicycle flashlight would be another.

Also, I have a 400 lumen flashlight that actually cost me $18, and is now down to $12. It's sold as an 800 lumen, but actual output is in the 400 lumen range. $25 would include a pair of 18650s and a charger. I've had it 2 years and it's been totally reliable. I only ever use the high mode when I'm using it as a backup headlight when I forget to charge my MagicShine battery.
