Kitletics Review · 8.4 Good
NITECORE NU43 is a run light / headlamp (1400 lumens class). 1400-lumen lightweight 18650-class integrated lamp (~116 g) with soft TrueVision flood — mid/high output when you want serious brightness without Distance 1500 mass or Petzl reactive cost. I'd shortlist it for 1400 lm at 116 g punches above most mid-weight running lamps. The trade-off is no rear light or reactive system — peers win for road visibility / auto-dim — Petzl Swift RL is the cleaner compare when that is most of your week. It fits buyers who actually need a run light / headlamp (1400 lumens class), not a one-product rotation.
