Minimalist Desk Lamp Light Projection Poster

A 4:5 vertical minimalist high-end desk lamp promotional poster. In the bottom-left corner stands a minimalist metal desk lamp with a slender stem, a matte deep red semi-cylindrical shade, and a realistic power cord tracing naturally along the desk surface. The lamp head projects a defined cone of warm white light toward the upper right. Standing vertically in the center are four dark indigo matte thin boards, evenly spaced. As the light beam travels through precise stencil cutouts in these boards, it projects onto the rear warm-grey wall to spell the word "[BEAM]". The letters are created purely by cast light with authentic optical dispersion and soft edges, maintaining realistic straight-line perspective from light source to cutouts to wall. Controlled highlights accentuate the board rims. In the bottom-right corner, small clean text reads "[ARC LAMP / LIGHT SHAPED BY FORM]". Restrained color palette of dark indigo, matte crimson red, warm grey, and warm white. Quiet indoor architectural night photography aesthetic, realistic materials, clean spatial depth, no smoke, no neon, no people, no brand logos.
