Nebo included a proprietary ICR 18650 lithium-ion battery, with a total capacity of 2200mAh. This is actually quite small for a battery nowadays. I don’t know why they couldn’t choose a 3000mAh or just use a 3500mAh battery. Since the light shouldn’t be pulling many Amps, a 3500 mAh battery would have been fine. To use the Nebo flashlight, press the power button on the side of the flashlight to turn it on. The LED indicator light will turn green when the flashlight is on. To clean this area, take a cotton swab or facial tissue and dip it into rubbing alcohol (it’s okay if you don’t have to rub alcohol; water will do in a pinch). Then wipe down both ends of the battery compartment to remove residue from old batteries. The last thing that could cause your light not to work is a loose wire or broken connection. To fix this, you will need to take your flashlight apart. If your flashlight is waterproof, don’t open it underwater or allow the electronics to get wet.

The measurements in the highest output mode weren’t too far off, but the lowest mode wasn’t close in terms of candelas. But when you just focus on the distance: 125 meters vs 107 meters, that doesn’t seem to be a big difference. Measurements were taken indoors at 5 meters with a Hagner E4-X Lux Meter. Measurements were recorded after 30 seconds, as per ANSI FL1 standards. ModeI also measured it between 20-30% from the outer ring of the beam, and it dropped to 7000K. The yellowish ring on the outside of the beam is about 4500K. If you’re traveling and need to charge your Nebo flashlight, you can use a car adapter to plug it into your vehicle’s cigarette lighter.

Conclusion The Highest output doesn’t drop as fast as you’d think. It takes almost 15 minutes to drop from about 2000 lumens down to 295 lumens. Yes, that’s low. At 2h14min it reaches 180 lumens (which is considered the end of the runtime as per ANSI 1FL standards). But the light continues to drop output and finally turns off after 3h14min. Battery was down to 2.7V.

Press and hold: ramping brightness up and down. It will blink at the highest and lowest output, but if you keep pressing the switch, it just continues ramping up and down
