Petzl – NAO 575 Lumens

Petzl – NAO 575 Lumens

Powerful, compact and reliable. These are words to describe the Petzl Nao 575, the direct predecessor of the Nao+. This headlamp has been around for two years, and there is a reason it is still a top-selling device. The quality and build of this device are surpassed only by its performance. A must-have for any serious hiker, camper or runner the Nao 575 delivers quality and performance together in the same package. The 2600 mAh Battery is rechargeable through  USB connection and can be replaced with AAA batteries if the need arises. And thanks to the pure white light from the headlamp, all colors are seen at night will be true to life. With a maximum setting of 575 Lumens, this lamp is super bright.  And with the Nao 575, you customize your headlamp even further with OS by Petzl software.

A sleek light design coupled with REACTIVE LIGHTING gives any runner or climber maximal brightness and a longer burn time. With REACTIVE LIGHTING, the sensor senses ambient light and adjusts to each task. It will dim while glancing down at a map and immediately return to its original setting as you look back up. This will lead to more visual comfort and less strain on the eyes. This type of lighting will give you optimal energy and burn time while giving the user a better hands-free experience.

A stable white light is a MUST when using a headlamp. The athlete needs that light to burn at the same strength all the time. The CONSTANT LIGHTING mode guarantees that your light will not fade during the chosen burn time. The two LEDs provide a flood or a spot or a combination light that meshes together to create a perfect blend of spot and flood that looks like one full light rather than two unique lights.

DISADVANTAGES

Once again PETZL has designed a lamp that is well built and powerful. I can only find two real flaws with the device. While the rechargeable battery can be replaced with Alkaline AAA batteries in an emergency, it is at a reduced performance level and the batteries will drain very fast. The best thing to do in this case is to buy a spare rechargeable battery from PETZL to swap out when needed. Which brings us to the next disadvantage, the burn time in CONSTANT LIGHTING at the max lumens. With a burn time of only 90 minutes at this setting, it seems a little short for a high-end device to have.

Since the PETZL NAO 575 has been around for a few years, there are approximately 100 reviews on Amazon with a strong four out of five-star rating.  Overall most users have been extremely satisfied with this device, specifically with the power of the light. One buyer stated that “Having the NAO 575 on my head is like having car headlamps on your head!” The even weight distribution and the REACTIVE LIGHT are mentioned in most reviews with most genuinely content with both.

The most critical review by a customer examined the learning curve of cycling through the control levels as the switch takes a turn than a pause. He proposed spending the time to understand how to cycle the levels at home before going it out in the field. This would allow you to make certain you know how to get the level of light that you need quickly.

VERDICT

The PETZL Nao 575 was voted as one of the top devices in 2016 and still is a fantastic device for ultra-runners and night owls who love to hike and climb in the dark. The REACTIVE LIGHTING will last for hours giving you the perfect amount of light when and where you need it. It will burn at the same strength, and can shine brighter than a car headlamp at 135 meters!  PETZL has proven that a sleek compact light can shine through the dark giving you that edge on a dark night to finish that climb or race. And at a reasonable price point, this lamp is an investment that you need to make.
