BioLite Range 500 Headlamp Review: Comfort-First Light for Camp and Trail

Fast. iRunFar says an 8-minute charge from dead gives an hour at 500 lumens, and empty to 80% takes 30 minutes. The battery is a 1,634 mAh lithium-ion cell, by BioLite's spec, charged over USB-C.

And no, you can't run it while it charges. iRunFar says it doesn't offer pass-through charging. BioLite's own FAQ points people who need that to its HeadLamp 800 Pro, which has a rear power source. The battery is built in, so there's no swapping in a spare.

Cold charging has its own limit. BioLite says the lamp operates from -20°C to +60°C and has a narrower range for recharging, for battery safety, and suggests keeping the headlamp and power bank in an inside pocket if you need to charge in the cold.

IP67, which BioLite explains as dust-tight, resistant to hoses and jet sprays, and submersible to 1 meter for up to 30 minutes. iRunFar used it in driving snow and rain with no issues.

On battery life over time, iRunFar saw no degradation in eight months of use. That's a good early sign, and it's all the long-term evidence I found. One sound habit from BioLite: if the lamp gets wet, let it dry before charging, and blow any dust out of the USB-C port first.

BioLite now offers a 3-year warranty on the Range series, per its own page and iRunFar. The lamp ships in lock mode, and a press-and-hold locks it off so it doesn't drain itself in your pack. Small thing. Saves a dead lamp.

Buy it for camp chores, dog walks, car camping and ordinary night hiking, where comfort and quick charging matter most. iRunFar keeps it in the car and the pack for exactly that, and would still pick a more powerful light for overnight technical efforts.

Its one real gripe is the buttons. iRunFar found them not as easy or intuitive as it hoped, and suggests gloves may make them trickier.

Owners: Amazon shows 4.2 stars from 76 ratings as of October 16, 2026, a small crowd. The price band ran $65-70 that day, matching BioLite's list price. BioLite's own lineup is the first comparison: the Range 400 and Range 300 sit one and two steps cheaper, with 400 and 300 lumens. If you want swappable batteries, a hybrid lamp like the Petzl Actik Core is the usual alternative. If you want the lightest lamp, a minimalist Nitecore is.

BioLite sells three Range lamps, and its comparison table is the most useful thing on the page. Here's the lineup, by BioLite's figures and prices as listed on October 16, 2026. Prices move, so treat the dollar figures as that day's snapshot.

The Range 500: 500 lumens, a 100 m beam, a 1,634 mAh battery, 2.6 oz, about seventy dollars. The Range 400: 400 lumens, 90 m, the same 1,634 mAh battery, 2.6 oz, about sixty. The Range 300: 300 lumens, 75 m, an 817 mAh battery, 1.8 oz, about forty.

Now the sum I couldn't resist. Divide lumens by dollars. The 500 gives about 7.1 lumens per dollar. The 400, about 6.7. The 300, about 7.5. So the Range 300 is the best value on light alone, and the middle one is the weakest.

Why buy the 500, then? BioLite says only the 400 and 500 get the new two-button interface, and the bigger battery doubles the run time on low and in red mode. The 500 adds the white flood. Same weight as the 400. 100 more lumens. Ten dollars. I'd pay it.
