Mostly. The Petzl NAO LT headlamp weighs 88 g and provides up to 600 lumens, which iRunFar reviewers found bright enough for trail running and comfortable to wear. However, its battery lasts only a couple of hours at maximum output, so it is better suited to shorter runs than full-night ultras.

Mostly. The Nitecore UT27 MCT Pro is a strong ultrarunning option for runners who value a 75 g lamp, three white colour temperatures and swappable rechargeable or AAA power. Its 800-lumen peak suits technical terrain, but medium mode may not last a full night, so plan to change batteries or use lower output.

Mostly. The UltrAspire Lumen 600 5.0 Waist Light looks suitable for ultrarunning if you prioritise a bright, adjustable beam and battery flexibility over low weight. Its 600-lumen output, 4-10-hour runtime and swappable, USB-C-rechargeable battery support longer outings, but its heavy, bulky fit may bother runners seeking minimal kit.
