Among Fenix’s headlamp lineup, there are currently two lithium battery-powered models: the HP30, a dual 18650 lithium battery separated headlamp, and the newly launched HL55, a single 18650 lithium battery integrated headlamp.
The Fenix HL55 is a high-performance single 18650 battery-powered integrated headlamp. It features a full metal body and weighs just 115 grams; with an ultra-bright mode of 900 lumens and four brightness levels, all easily controlled via a side switch, it perfectly balances different brightness needs and battery life requirements. In addition, it offers constant brightness, IPX-8 waterproofing, and compatibility with cold-resistant CR123A batteries, making the HL55 an excellent choice for outdoor activities such as caving and high-altitude climbing.
The HL55 is equipped with a Cree XM-L2 T6 neutral white LED, offering excellent color rendering and strong penetration. Its highest constant brightness level is 420 lumens, with a runtime of nearly 4 hours on this setting—a very practical option. The 900-lumen turbo mode can be activated by holding the side switch for one second in any state, and after 30 seconds of maximum brightness, it automatically returns to the previous brightness level.
The exceptional brightness-to-size ratio is another highlight of the HL55. It measures 84 mm in length, 46 mm in width, and 48 mm in height, and weighs only 115 grams (excluding battery), so even during trail running, the head load feels relatively light. Compared to AA batteries, the use of 18650 lithium batteries offers clear advantages. The HL55 can run on either a single 18650 lithium battery or two cold-resistant CR123A batteries.
In short, the single 18650 lithium battery-powered HL55 combines advantages in weight, size, brightness, and battery life. Whether for high-altitude climbing, trail running, hiking, trekking, or camping, the HL55 proves its worth.
