The packaging:

The Nitecore HA23 is sold in the classic Nitecore cardboard package with yellow / black coloring. The box shows the main features of the torch including the 5-year warranty and the product serial number.

Inside the package we find the NITECORE HA23 headlamp, the headband, 2x 1.5V Alkaline AA batteries, user manual and warranty certificate.

-------------------------------------------------------------------------------

The Nitecore HA23 is a lightweight headlamp ideal for outdoor activities. Made of durable and lightweight polycarbonate, it produces up to 250 lumens of light with the possibility of reaching 60 meters of beam,
ideal for trekking and camping thanks to its lighting that covers an angle of 150 degrees. It is then powered by 2 AA batteries, primary or rechargeable, commonly used and easily available that allow up to 130
hours of autonomy.
The Nitecore HA23 is IP67 certified with 1 meter impact resistance.

The Headband supplied with the Nitecore HA23 is light and can be worn well even for long periods without problems. It is also equipped with an upper band for a better grip.
The HA23 has 4 angle settings covering an angle of 70 °.

Let's see the inscriptions on the HA23.

-------------------------------------------------------------------------------

The Nitecore HA23 uses a CREE XP-G2 S3 LED capable of delivering a maximum power of 250 lumens and a maximum intensity of 800cd peak through a TIR optic and lens with honeycomb weaving.

For all operations we will only use a mechanical switch on the right side of the Headlamp. The rubber button has a noisy click and is operated with the right pressure.

The battery compartment is characterized by a snap closure, once inserted the two AA batteries just press to close the contact confirmed by a noisy click. To open, simply press the clip located near the door.
Around the door we then have the rubber gasket for protection against water and dust. The Nitecore HA23 is protected against polarity reversal; if we look closely, we notice the two vines that act as a thickness, thus preventing the flat contact of the battery negative.
For the contacts we have, on both sides, on the positive side a button and on the negative side a spring.

Operating Instructions:

The Nitecore HA23 is equipped with 3 brightness levels and 1 special mode:

HIGH: 250 lumens (3h.30min.)
MID: 65 lumens (17h.)
LOW: 2 lumens (130h.)
Beacon

On/Off
On: When the light is off, press the switch until a click sound is heard to turn on the light.
Off: When the light is on, press the switch until a click sound is heard to turn off the light.

Brightness Levels
The HA23 has 3 brightness levels and BEACON Mode.
When the light is on, half press the switch to cycle through the following brightness levels: LOW – MID – HIGH – BEACON. When shut down and reactivated in over 5 seconds, it will automatically access LOW
Level.

Timing Protection Function
The HA23 will regulate its output to avoid overheating and prolong the lifespan of the batteries when accessing the HIGH Level for over 10 minutes.
Cautions:
1. Please use high-quality batteries. When the product is left unused for prolonged time, please remove all batteries to prevent battery leakage due to possible poor quality of the batteries.
2. DO NOT direct the beam towards naked eyes.
3. DO NOT disassemble, modify or reconstruct the product, otherwise the warranty will be nullified, and the product might be damaged.

Changing Batteries
The batteries should be replaced when the output appears to be dim or the headlamp becomes unresponsive due to low power.

Beam and Runtime:

The Nitecore beam is well made, proven in the evening it has a lighting that covers a large angle starting from the feet.
Good beam color and quality.

The runtime was performed internally with the two alkaline batteries supplied with the torch and subsequently with two AA Ni-ME LADDA 2450 mAh batteries. Good durability, as can be seen from the graph, there is a slight decrease in luminous intensity after 10 minutes from ignition.

The two curves side by side.

CONCLUSIONS:

With the HA23 Nitecore proposes, at a price accessible to all, a compact product and immediately ready to be used. The package comes complete with headband and AA alkaline batteries, which are however easily available. Despite the only 250 lumens I would recommend the Nitecore HA23 for those who do trekking, running and camping and given its small size and weight it is easy to put it in a backpack and then use it in times of need. Good runtime if we also consider the possibility of using the best performing Ni-MH batteries.

Thank you for reading the review.

I have been looking for a nice 2 cell double A headlamp for sometime. Just noticed your review a few days ago. Purchased a Nitecore HA23 from Amazon. Delivered today. So far I love it. I did not want to spend close to $50.00 for the Fenix version of the headlamp. Most of the generic plastic triple A headlamps are not worth the money. My HA23 has a nice tint also. Nice review Roma58. Great photos and graphs.
