The Bilby 400 has been designed from the ground-up for serious outdoor adventure. It’s powerfully bright, tough, intuitive and sets a new standard for multi-purpose headlamps.

The innovative design consists of a waterproof, dust-proof, USB rechargeable light pod, paired with a supremely comfortable and durable medical-grade silicone strap - together weighing just 3.2 oz.

The Bilby produces a serious output of up to 400-lumens from 5 optimally placed LEDs and offers an impressive 5-hour runtime on full power, and over 105-hours on the lowest setting.

The Bilby 400 is also compatible with Knog’s Modemaker app, so you can customize your light settings anytime. Simplify or amplify, the choice is yours.

The 5 LEDs on the Bilby are optimally placed for their individual purposes. A Spot beam for distance, two elliptical beams for Mid and Wider angles, a Red light for night light purposes and Downlights for reading.

For maximum brightness, use Boost Mode (both Spot + Mid) to get 400 lumens for an impressive 5 hrs. For the longest runtime of 105 hours, use the Mid LED on the lowest brightness setting.

Special Features You’ll Only Get With Bilby 400


The Bilby 400 is the only headlamp in the world that you can program at home. Using Knog’s free Modemaker App, you’ll have access to a library of 26 different light modes that can be added / removed any time you like. Simply plug in and program.


For moments when you really need to light things up, a quick double tap of either button will engage Boost Mode. This fully powers both the Wide & Spot LEDs, providing up to 400 lumens for 10 minutes.


Through the use of the 2-intuitive buttons, users can electronically raise and lower the light beam over a 20-degree arc which overcomes the need for the traditional mechanical adjustment ensuring the light points right where you need it when you need it.


The outstanding feature of this design is having the USB integrated into the removable lighting pod. To recharge, simply plug the pod into a USB-A port, and you’ll have a full charge in just 4 hours. Goodbye cables & single use batteries.


The strap is moulded from medical grade silicone that’s extremely comfortable, durable and flexible. It’s one-size-fits-all and adjustable to fit head circumferences from 11.8 to 26 in using a simple toggle. Adjust on-the-go or set and forget.
