Nitecore NU27 600
Ranked #4 in Best Rechargeable Headlamps
Nitecore NU27 600
3 sources2 derived$44.95as of Aug 1

The Nitecore NU27 headlamp lets you dial color temperature between warm, neutral, and cool white, which covers a range of outdoor activities. Reviewers noted the light 1.98 oz body and USB-C charging that finishes in about 1.25 hours. Brightness modes are plentiful and performance holds steady across the color settings. Criticism landed on the removable headlamp body, which reviewers saw as having no practical benefit, and on a charging indicator that gives little clear visual feedback. Hikers and campers who want a light, multi-function lamp will like it; anyone who needs a sturdier attachment system should look at other models.

Strengths
  • — Adjustable color temperature with warm white, neutral white, and cool white emitters
  • — USB-C charging with 1.25-hour charging time
  • — Lightweight design at 1.98 oz
Watch-outs
  • — Headlamp body can be easily removed from headband without practical benefit
  • — Charging indicator uses only blue LEDs without clear visual feedback of charge level

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

BioLite Range 500

The BioLite Range 500 offers faster charging than the Knog Bandicoot 250, which charges in 30 minutes versus 2.1 oz's 2.5 hours, and provides more consistent runtime at 200 hours on low. However, it's not as bright as the Fenix HM50R v2, which delivers 700 lumens, and lacks the IP68 waterproofing of the Fenix.

Nitecore NU27 600

The Nitecore NU27 600 stands out from the Petzl SWIFT LT with its adjustable color temperature feature, which the Petzl lacks. However, it's less durable than the Fenix HM50R v2, which has an IP68 rating and more robust aluminum construction, and it doesn't offer the reactive lighting technology of the Petzl SWIFT LT.
