Review summary
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.

What it is
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, plus large integrated cell supports long low-mode winter nights. I'd pause when no rear light or reactive system — peers win for road visibility / auto-dim, plus integrated cell only — no hot-swap pack like Distance 1500 is most of your week — Petzl Swift RL is the cleaner starting compare. Generation NU43 is the current reference.
Key specs

Keep it when 1400 lm at 116 g punches above most mid-weight running lamps, plus large integrated cell supports long low-mode winter nights is the week; skip it when no rear light or reactive system — peers win for road visibility / auto-dim, plus integrated cell only — no hot-swap pack like Distance 1500 is the pattern.
Durability
Durability belongs in a run light / headlamp (1400 lumens class) rotation, not a forever one-product plan. no rear light or reactive system — peers win for road visibility / auto-dim, plus integrated cell only — no hot-swap pack like Distance 1500 is the ownership limit to weigh against 1400 lm at 116 g punches above most mid-weight running lamps, plus large integrated cell supports long low-mode winter nights.
