Nitecore NU20 LED Headlamp

Incredible Power

Providing ample output in a compact design, the NU20 LED Headlamp is one of Nitecore's smallest and most efficient headlamps to date. Equipped with a powerful CREE XP-G2 S3 LED, this tiny illuminator can produce up to 360 Lumens of brilliant white light that can reach over 250 feet away, providing all the illumination you'll need for up close activities or for viewing from a distance. The light also comes with 3 dimmer outputs ranging from 220 Lumens down to just 1 Lumen, as well as a pair of tactical outputs for unique situations. The headlamp uses a specialized micro-textured reflector that allows it to provide 100 degrees of evenly dispersed light, clearly illuminating anything in your line of sight. The NU20 is operated using a simple push-button switch on its body and is attached to a special hollow-carved head clip which allows it to pivot up to 52 degrees vertically, allowing for a wide variety of lighting angles to fit any situation.

Designed for the Active User

The NU20 is designed to be as convenient as it is capable. At just over two inches in length and weighing under 2 ounces, this little lamp won't weigh you down, making it ideal for camping trips, late night runs, and other active endeavors. Crafted from durable polycarbonate materials, this rugged light is both waterproof and impact resistant, allowing it to endure the wear and tear of the elements and frequent use. The lamp's easily-adjustable headband conforms to nearly any head size and is made from comfortable but tough nylon material.

Internal Power Source

Unlike most headlamps, the NU20 has no need for replacement batteries, instead it has been designed with a convenient rechargeable Lithium Ion battery pack. The potent battery pack can power the lamp on its highest output for 30 minutes and can run its 1 Lumen output for an astounding 100 hours before needing to recharge! The 600 mAh battery is recharged internally via the light's convenient micro-USB charging port and can be recharged up to 500 times before seeing any notable drop in its capacity.

I absolutely Love this Rechargeable Headlamp
October 15, 2018
I needed a headlamp that was comfortable, light, and bright so I gave the Nitecore Nu20 a try. Oh boy am I pleased. My main use is for Estate sales for basements can be dim, plus I use for electronics repairs. Works well for both applications this headlamp is perfect. I run on high and it will last all day on a single charge plus it is so easy to charge USB. This headlamp is underpriced for what it does and really performs. Thank You Battery Junction for offering this winner.

Lightweight headlamp. Runtimes could be better.

I have the NU17 headlamp and wanted something with a little more brightness. The NU20 provides that while maintaining a small size. It is lightweight and has decent spreads between modes. Low at 1 LU, Med at 40 LU, High at 220 LU and Turbo 360 LU. Im not a big fan of 1 LU though. I prefer 2 to 5 LU for a low setting instead. 220 LU and 360 LU are pretty close together as well. The strap does not have the over-the-head strap, but there is about 10 of a silicon type bead on the inside of the headband that helps in keeping the headband from sliding down your head. It would have been nice if that grippy material ran the entire length on the inside of the headband. The headband is adjustable in length and can easily fit around a cap or helmet. The included USB cable is long at about 38. The headlamp has five secure tilt adjustments.

I was confused by the specs that claim 30 MINUTES on Turbo, but further in the description, it states Turbo will step down to High after 30 SECONDS. That is a far cry from 30 mins. It did step down after 30 seconds from Turbo to High in my testing. I tried going from Turbo several more times and every time, Turbo lasted a few seconds shorter and shorter than the time prior before it would step back down to High. I ran a runtime test on High to test the listed 6 hrs on the specs with the light fully charged. I got about 1.5 hrs, before it obviously began to step down to Med. I turned it off and found I could still obtain Turbo for about 5 seconds before it stepped down to High. After about 3 hrs on a diminishing High mode, it stepped down to Med and I could only reach the lower two modes now. The battery indicator blinked twice at this point. The light did not get hot during my testing. I found the runtimes far lower than the advertised specs, but that is often the case in the flashlight world. The battery indicator did not appear very accurate either. Two blinks gave the false impression of 50 percent battery life remaining. It was more like 25 percent. This headlamp is still a very useful tool. The headlamp being rechargeable helps. Charging an almost completely dead battery took about 2.5 hrs. Just keep in mind the exaggerated runtimes.

Great product!

I recently needed to use the headlamp while working on plumbing in a dark area. The light was perfect for my needs. It was able to adjust in brightness and in the angle of throw no matter which position my head was in.. The charge lasted as long as was needed. The charging cord can be stored attached to the back of the head strap even while in use.
