The Detail
Small in size. Big on lumens

248g —battery included— for a full 800 lumens. Charging via USB-C. Whether it is for a quick run in the city or camping in the backcountry, this headlamp will never leave you!

IP67 and weather resistant

The Bright As Day 800 is weather sealed against splashes, heavy rain and extremely moist conditions. It can deal with extreme cold weather down -20ºC.

'Aluminium blade' passive cooling

The aluminium blades allow for the electronics to function constantly at their full potential and avoid overheating. It will never decrease lumens to cool itself.

GoPro QuickClip compatible

A Moonlight signature, all of our headlamps feature the GoPro QuickClip compatibility to ease the switch from one setup to another!



The go-to lamp for everyday training and racing! The light is still really strong with a nice even spread but it is still super lightweight. Most lamps this weight and size have half the lumens.

Jon Albon, World Champion (Skyrunning, Spartan, OCR & Trail)

Compact and extremely powerful, the BAD 800 gives you the freedom to decide if you wanna go longer because you will always carry one of these when out adventuring! Whether it's Winter or Summer!

Martina Valmassoi, Skimo racer and Skyrunner

Excellent craftsmanship, with focus on the small details and supported with their extensive testing. Staff’s engagement in personal support direct to customer is honorable and sincere.

Martina Valmassoi, Skimo racer and Skyrunner

The removable battery, extension cable, interchangeability and the GoPro mount flexibility make them an excellent choice. Although not cheap, you get what you pay for and one thing is for sure, they will last.
