Create a detailed 3D model of a modern, sleek desk lamp with a minimalist design. The lamp should have a curved, slender metallic arm extending from a small circular base. The lamp head is adjustable and round, with a smooth, glossy surface. Incorporate a soft, subtle light source at the top, casting a warm, inviting glow. The materials should appear realistic, with reflective metal textures for the arm and matte surfaces for the base.
