Depends on scenario. I prefer to have replaceable batteries and often use rechargeable ones. Walking in the woods with scouts and it's dying I can swap new ones from my backpack and keep going. I can recharge when we get back. I can stop at a store if I need more.Whatever you get, make sure it's rechargeable and doesn't use disposable batteries.
This is absolutely true! Since I have a lift I try avoid being on my back whenever possible but that's not possible for everyone.This 700 lumen Braun model is rechargeable and contains the batteries in the light module. The headlights with the battery pack attached to the back of the headband are cumbersome when lying on the ground working under a vehicle. Also, select a headlight with a band across the top of the head; otherwise, the light will tend to slide down over time. This unit has the adjustable focal lens (i.e., spotlight to wide beam), tilt adjustment and adapter hooks for use on a hardhat.

I can’t believe I didn’t think of them when I started searching. I’ve got one of their “mounted” options and it’s been great. Thanks for this.try a Princeton head lamp, it's all I ever used at work,,by far the best one ever , a bit pricey though they are true professional grade.
