Petzl ACTIK CORE’s Output Changes With Its Power Source

RESEARCH-BASED PRODUCT FEATURE
Based on published manufacturer specifications. Gunfire Magazine has not physically tested this product for this article.

Petzl’s current ACTIK CORE headlamp accepts either the supplied CORE rechargeable battery or three AAA/LR03 cells. That flexibility is a defining feature, but the published lighting table shows why the power source should stay attached to an output claim.

625 lumens is a specific configuration

The current page lists a 625-lumen maximum with the CORE battery and 450 lumens with three AAA cells. Petzl gives the lamp a weight of 88 grams and an IPX4 weather-resistance rating. Its rechargeable battery uses USB-C; the charging cable is not included.

The page also gives different performance figures for other lighting levels. The largest lumen number is not a description of every mode or every battery arrangement.

A familiar name can span generations

Earlier ACTIK CORE listings can show different maximum outputs. Our assessment is that the actual reference and generation should be identified before a specification is attached to an image or review. An older photograph alone cannot prove that it depicts the current 625-lumen version.

Gunfire has not independently measured output, beam distance or runtime. The figures here are Petzl’s published data, checked November 2, 2026, rather than a field-test verdict.

Look beyond the headline brightness

A useful evaluation would consider beam shape, comfort, controls and power availability during the intended outing. It would also state the battery and lighting level used for every endurance claim.
