Review summary

Rechargeable RGB LED armband (~6 lm) with steady/flash modes — low-profile wearable visibility for dusk road miles without a full illuminated vest. Here's a practical take on the Nathan LightBender RX Armband Light — what it's for, who it suits, and when to pick something else. I'd shortlist it if you want comfortable armband form factor with long flash runtime, rGB modes help customize visibility against clothing colors or iPX4 and USB recharge for wet winter training. Skip it if can chafe on bare arms — better over sleeves or marker light only — not a trail headlamp substitute is most of your week. Nathan LightBender RX Armband Light is a visibility / safety gear.
