Unboxing and First Impressions
The Olight H05 arrived in simple packaging, nothing fancy. First impressions were positive; it's incredibly lightweight and compact – a huge plus for any outdoor enthusiast. The build quality felt surprisingly sturdy for its price point. The elastic headband is adjustable and comfortable.

It comes in a variety of colors (I have green, orange, and blue), adding a nice touch of personalization. The simplicity of the design is refreshing; no unnecessary bells and whistles.
Features and Functionality
The Olight H05 boasts a bright main beam with a surprisingly good focus, and additional red LEDs for preserving night vision. This is a fantastic feature for nighttime activities without compromising visibility.

The controls are intuitive – simple clicks to cycle through brightness modes (high, medium, low) and red light, with a double-click to toggle between white and red. Battery life is impressive, lasting for days on a single set of two AAA batteries.

Real-World Performance
I've used the Olight H05 extensively on camping trips and various outdoor activities. The lightweight design and long battery life were invaluable. Its compact size makes it perfect for stuffing into any pack or gear.

Even during multi-day excursions, battery changes weren’t needed. The brightness levels are sufficient for most tasks, from navigating trails to fixing equipment.

My friends also love their H05 headlamps; one uses it for his handyman business, another for long-distance running at night.
Specifications and Battery Life
The Olight H05 utilizes two AAA batteries instead of the usual three, keeping it remarkably lightweight. On high, you get approximately 150 lumens (dropping to 90 lumens as the battery depletes), lasting several hours.

The medium mode offers around 30 lumens for up to 7 hours. The low mode provides around 10 lumens for a considerable battery duration, suitable for minimal illumination.

This translates to 3-4 days of usage during my camping trips without needing a battery swap—a considerable advantage over most headlamps in this price range.
Conclusion
The Olight H05 headlamp punches well above its weight and price. Its lightweight design, robust build quality, long battery life, and multiple brightness settings make it an excellent choice for various applications, from outdoor adventures to everyday tasks.

While it lacks some features found in more expensive headlamps (e.g., a more ruggedized design or a rechargeable battery), these omissions are easily outweighed by its affordability and practicality. The Olight H05 is a highly recommended budget-friendly headlamp for anyone seeking a reliable and versatile lighting solution.
