It features a standard GoPro-style mount on the bottom to easily fit GoPro mounts. The [qudos] delivers 400 lumens of continuous light from Cree LEDs. The three LED bulbs can be used all at once or an a several combinations.
The individual LEDs each have different lenses in front of them for different applications, offering a wide beam, a narrow beam or ultra-wide angle beam. They can also be selected in high or low power levels. Just cycle through the lighting modes by pressing the single button on top of the unit. It is a very simple and intuitive way to operate the unit – no overthinking the UI here.
It is powered by a removable 1000mAh lithium-polymer rechargeable battery, which can be charged over a micro USB cable. The specs quote up to 4.3 hours of use per charge. Spare batteries are available as well.
In addition to the GoPro mounting options, the [qudos] is also geared toward camera-top use on DSLRs thanks to an included adapter. The [qudos] provides light at about 5000k color temperature, so it’s much closer to daylight-balanced than the typical indoor kelvin light at 3200k. If you’re shooting indoors though, it should be easy enough to slap a CTO gel on the front even though Knog doesn’t yet offer a filter mounting system.
The housing of the light is a tough, marine grade aluminum, which serves double duty as a heat sink for the battery. An optical grade thermoplastic rear door is sealed with a gasket and the unit is waterproof down to 40m (131′). The clear door allows you to easily see the indicator lights to confirm which lighting mode the [qudos] is in.
The [qudos] ships with both the cold shoe (referenced above) and the dual GoPro/[qudos] mount for mounting the camera and light side-by-side. There’s also a tacky spacer in the box that helps keep the light and camera level with each other and pointing in the same direction during extreme use.
The Knog [qudos] retails for $119.95. Check it out here at B&H Photo.
