Overview
Trail runs, ski tours and alpine starts in the dark are where Petzl aims the Swift RL, a rechargeable headlamp with a light sensor that changes brightness and beam shape on its own. A split strap spreads the hold across the head, and red light covers close work.
Reactive Lighting earns its place: the sensor dims the beam when you look at a map and opens it up on the trail, which stretches the charge without button presses. On the downside, the listing gives two runtime figures without naming the modes, and its title and specs disagree on peak output.
Who it's for
Runners, skiers and climbers who change pace and terrain quickly get a beam that reacts for them and a strap that stays put. Campers who mostly read in a tent need far less output and may never use the sensor.
Pros and cons
- Light sensor adjusts brightness automatically
- Red light protects night vision
- Strobe mode for emergency signaling
- Charges over USB-C
- Runtime figures not tied to specific modes
- Title and specs disagree on peak lumens
- Rated only as water resistant
Performance notes
Output on the trail is governed by the light sensor, which reads ambient light and scales brightness and beam pattern to match. Sensor mode stretches burn time because the lamp only runs bright when the scene calls for it. Manual high output drains the battery much faster than reactive mode.

Frequently asked questions
Does the Petzl Swift RL use AAA batteries?
The bullets describe a 2350 mAh lithium-ion battery, included, that charges via USB-C. One spec line mentions AAA batteries, but the included component is the SWIFT RL battery, so treat it as a rechargeable lamp.
Is the Petzl Swift RL waterproof?
It is listed as water resistant. No submersion rating is given, so do not treat it as waterproof.
What does Reactive Lighting do on the Petzl Swift RL?
A light sensor adjusts brightness and beam pattern to the ambient light, which extends burn time and reduces manual adjustments.
Does the Petzl Swift RL have a lock?
Yes, a lock function is listed among its features.
