The color rendering of this Lupo lamp is excellent and the intensity remains unchanged when the variable color temperature is adjusted from 3200K to 5600K. The build quality also surprised me. I've had plastic LED lights before (on the stands and on the camera) but this one looks much sturdier. Durability is closer to that of a metal case (no added weight). There is a 1/4" 20 screw on the top and bottom for attachment to an articulating arm, light stand, or camera mount. The diffusion softens the light enough to remove micro shadows, but I like the directional narrow beam angle. Usually I shoot videos but this light saved me on a recent photo shoot where I needed extra lighting from behind and around the edges.An excellent light source to use in any situation (direct, diffused or reflected).
