Description

NITECORE HA11 Multipurpose Ultra Lightweight AA Headlamp, 240 Lumens

The NITECORE HA11 is an ultra-lightweight multipurpose headlamp designed for hiking, trekking, running, camping, travel and emergency use. Delivering up to 240 lumens with a maximum beam distance of 90 metres, it combines efficient white illumination with a separate red-light function in a compact headlamp weighing only 38 g including the bracket and headband.

The HA11 uses a high-efficiency dual-core NiteLab UHE LED system and offers three white-light brightness levels, red constant illumination, red slow flashing, SOS and Beacon modes. Two differently shaped control buttons make the functions easier to distinguish by touch and allow convenient one-handed operation.

One of the HA11's major advantages is its flexible power system. It can operate from a widely available AA battery or from a compatible 14500 Li-ion rechargeable battery such as the NITECORE NL1411R. With a standard alkaline AA battery, maximum runtime reaches 75 hours, while the 1,100 mAh NL1411R can extend Ultralow runtime to as much as 126 hours.

A clip is supplied in addition to the headband, allowing the light to be attached to suitable cap brims, backpack straps and other equipment when conventional head-mounted use is not required.

Ultra-Lightweight Headlamp

With a stated weight of only 38 g including the mounting bracket and headband, the HA11 is designed to minimise unnecessary weight during outdoor activities.

With the supplied alkaline AA battery installed, the complete operating weight is approximately 62 g. This makes the headlamp particularly suitable for activities where low equipment weight is important, including trekking, running, backpacking and travel.

240-Lumen White Light

The HA11 produces a maximum white-light output of 240 lumens, reaching approximately 90 metres with a peak beam intensity of 2,030 cd.

A unibody optical lens system with multiple facets is used to shape and distribute the beam for practical outdoor illumination.

White-Light Brightness Levels

The HA11 provides three white-light levels:

• High: 240 lumens
• Low: 60 lumens
• Ultralow: 6 lumens

High provides maximum visibility for trail navigation and identifying objects at greater distances, while Low is suited to general movement and camp use. The 6-lumen Ultralow mode provides economical close-range illumination when long battery life is more important than maximum brightness.

During prolonged operation at High, output may automatically decrease to help prevent overheating and extend battery life.

• Stargazing
• Night photography
• Emergency preparedness
• Low-light navigation
• Situations where reduced disturbance to surrounding users is desirable

The red light offers both constant-on and slow-flashing operation.

SOS and Beacon Modes

Two white-light signalling modes are available:

• SOS – 240 lumens
• Beacon – 240 lumens

These modes provide additional signalling capability for outdoor and emergency situations.

Two-Button Operation

The HA11 uses two buttons with different shapes and tactile characteristics so that they can be distinguished more easily by touch.

• Power Button: controls switching on/off and white-light brightness.
• MODE Button: controls light-source selection and access to special modes.

Lockout Mode

The HA11 includes a useful Lockout Mode designed to prevent accidental activation during transport or storage.

To lock:

1. Switch the headlamp off.
2. Press and hold both buttons simultaneously for approximately 2 seconds.
3. The light flashes three times to confirm Lockout Mode.

When locked, normal brightness levels and special modes cannot be activated. Pressing either button causes a single flash to indicate that the lock is active.

To unlock:

1. Press and hold both buttons simultaneously for approximately 2 seconds.
2. The headlamp enters Ultralow to indicate that it has been unlocked.

Lockout Mode is particularly useful when carrying the headlamp inside a pocket, backpack or equipment pouch.

Headlamp and Clip Use

The supplied headband provides conventional hands-free headlamp use, while the supplied clip expands the possible mounting options.

Depending on the equipment and attachment point, the clip can be used to mount the HA11 to suitable:

• Cap brims
• Backpack straps
• Shoulder straps
• Webbing or similar equipment

Always ensure that the clip is securely attached before moving or beginning strenuous activity.

Durable PC Construction

The HA11 body is made from a special PC plastic selected for impact resistance and performance at low temperatures.

The lightweight polymer construction helps keep the complete headlamp weight low without requiring a conventional aluminium flashlight body.

IP66 Dust and Water Protection

The HA11 is rated IP66, providing protection against dust and powerful water jets. This makes it suitable for outdoor use in rain and wet conditions.

IP66 does not mean that the headlamp is designed for immersion or underwater use.

Ensure the battery compartment is properly closed before exposure to rain or water.

Impact Resistance

The manufacturer specifies impact resistance to 1 metre.

Impact resistance reduces the risk of damage from normal accidental drops but does not make the headlamp indestructible. Inspect the lamp and battery compartment after a significant impact before continuing use.
