light, compact and elegant design. Light does not flicker, it is stable and... WHITE. Cheap (at least cheap looking) filters are provided that can be inserted into a special slot in front of the light. These filters alter the light color (light "warmth") to mimic indoors or "golden hour" light.
I bought two of these. Two at full power can illuminate a dark 3x3 area which is apprx 1-1.5m away from them enough to take a handheld picture. Do not expect them to turn night into day. They can be used effectively as constant spot lights to enhance shadows, combined with a flash.... or without a flash at lower shutter speeds or higher iso settings for more shadowy portaits..... ah... I just nailed the topic... portraits... I don't see these lights being used for group photos or landscape photos (obviously). These lights (from a photographer's point of view - not a videographer's) are useful for facial or even full body portraits when the desire is not to fully illuminate the subject but to create nice shadows> Being constant lights, with adjustable outpout, very small and cool , easily placed on tripods or even on the ground, makes them great for this application. You place them where you want around your subject and you can immediately inspect the shadows and the intensity of the shadows these will create. Naturally, they can be combined with other lights or with an on camera flash
