Two LED indoor power boxes are juxtaposed on the surface of dark gray suede material, forming an oblique 45-degree angle. The front box is a black body with red terminals on the side; the rear box is a silver gray body with blue terminals. Snowflake-shaped hollow heat dissipation holes are distributed on the surface, and the words "LED INDOOR POWER SUPPLY 400W-24V-E" and parameter identification are clearly printed on the front. Soft side light brightens the box body from the top left, the metal shell is cool and shiny, the connection terminals are bright and contrasted, and the dark part of the background creates a low-key industrial style, highlighting the precision structure and industrial design sense of the power box.
